AP08856371 “Developing a resource-saving technology of repairing long rods of hydraulic cylinders of large-sized special industrial equipment with the possibility of restoring local damage at the site of its operation”. Project manager G.S. Zhetessova
Relevance
At present, for hydraulic cylinders of large-sized special equipment for industrial use, a widespread practice is producing rods with the galvanized chromium coating (GCC), which provides wear resistance, anti-corrosion properties, decreasing the coefficient of friction, and resistance to chemical and thermal effects of the environment. The need to use protective coatings is caused by high loads and severe operating conditions of the equipment. However, when repairing the inevitable local damage to the surface of the rods, it is possible to achieve original characteristics of the product only by completely re-chrome-plating the surface, the cost of which can reach 70% of the cost of the product. The idea of this project is to develop a cheaper alternative technology for the repair of long large-sized rods over the entire surface, as well as with to eliminate local damage based on thermal spraying processes, which will allow carrying out repair work at the site of equipment operation with obtaining a wear-resistant coating that is not inferior in its properties to GCC.
The project purpose
The development of a technology for repairing damage to the chrome-plated surface of long rods of hydraulic cylinders of large-sized special equipment for industrial use based on thermal spraying methods, which will be a cheap, environmentally friendly alternative to the process of re-chrome-plating plating and will provide higher properties of the restored surface compared to other repair technologies used today, and will also give the possibility of carrying out repair work at the site.
Expected and achieved results
- The analysis of the latest scientific developments in the field of coating has been carried out, taking into account the data of the operating conditions of the rods.
- Grades of steels used for manufacturing long large-sized rods have been analyzed.
- Systematization of the data of flake susceptibility, tendency to cracking, etc. has been carried out for rod steels.
- The factors influencing formation of cracks in the studied steels under the given conditions and the development of measures for their prevention have been revealed.
- A method of coating the entire product has been developed.
- A method of local restoration of the damaged layer has been developed.
- An additional data analysis and classification of rod surface damages have been carried out. The nature and dimensions of typical damage to the surface of the rods have been determined.
- A method of preparing the substrate before the local restoration of the surface has been developed, taking into account the nature of the damage and characteristics of the spraying process. The stages of preparing and work execution techniques have been determined.
Implementation of the project is based on the use of an integrated research method including a theoretical analysis that is based on the use of static methods of analyzing the properties of steels, which must be taken into account when developing a coating technology. On its basis the experimental verification of the proposed technical and chemical solutions in laboratory conditions has been carried out. All the studies have been carried out according to a single methodology, which allows obtaining reliable results. The project also uses methods of simulation, field and time observation, methods of mathematical statistics and data processing and assessment of their reliability. In the course of solving the tasks in the project, numerical experiments have been carried out using the method of computer modeling (Figures 1, 2), the purpose of which is to assess the thermal effect of the spraying process on the workpiece and to simulate preheating of the surface, taking into account the real dimensions of long large-sized parts.
Temperature distribution (°С) in the wall of the hydraulic cylinder rod (when calculating the hydraulic cylinder 105x90x1000 mm made of 20MnV6 steel, the process duration 50 sec)
in the thermal spraying process:
a) in the model, the hydraulic cylinder rod without thermal spray coating;
b) the rod of the hydraulic cylinder with a formed protective coating based on a nickel alloy with tungsten carbides
The possibility of commercializing the project results is planned by concluding a license agreement with industrial enterprises engaged in the repair, restoration, manufacture, operation of large-sized industrial equipment. It is planned to develop a strategy, a business plan for the further commercialization of the project.

AP08855477 “Developing and implementing the technology of producing Nihard-class cast irons with improved operational properties for parts of mining and metallurgical equipment” Project manager A.Z. Issagulov A.Z.
Relevance
A number of parts for mining and metallurgical equipment are made of Nihard cast irons (grates, fittings, plates, pump parts, etc.). Despite significant advantages of using these cast irons, they also have their own disadvantages: relatively poor casting properties (low fluidity, high shrinkage), besides, cutting when manufacturing parts of castings is difficult. In this project, it is planned to ensure the required operational and technological properties of Nihard grade cast irons in relation to specific parts of equipment of mining and processing plants by selecting the state of the metal base, applying corrected alloying and modification, using improved modes of crystallization and heat treatment. The issue of making thin-walled and shaped castings will also be resolved.
The project purpose
Developing and implementing the technology of producing parts for mining and metallurgical equipment using Nihard cast iron with an optimal set of properties depending on the operating conditions of the parts, which will increase the service life by 1.5-2 times.
Expected and achieved results
Based on the information analysis and taking into account the development of foundry production in the Republic of Kazakhstan, the optimal casting method of obtaining products of Nihard cast irons was determined, tendencies for improving the structure and properties of Nihard cast irons were determined, taking into account the raw materials base of the Republic of Kazakhstan.
Based on the results of primary laboratory studies, the optimal composition of the cold-resistant mixture for cast irons of the Nihard class was determined (refractory filler quartz sand 89% (in the proportion 1K0315 65%+1K02 35%), clay 2%; resin 7 – 8%, hardener consumption 1%, glycerin 0.03%).

a – Nihard 2 (martensitic-bainitic matrix, carbides); b – alloy 3 (non-etched structure, nodular graphite)
Figure – Structure of alloys X 1000
A new alloy composition has been developed based on Nihard cast iron including carbon, silicon, manganese, nickel, molybdenum, chromium, copper, cerium, iron and titanium carbide with the following ratio of components, wt%: С 2.6-3, 0; Si 1.5-2.5; Mn 0.6; Ni 4.0-5.0; Cr 3.0-5.0; Mo 0.5; Ce 0.1-0.15; TiC 0.5-1.0; Cu 0.2; S≤0.05; P ≤ 0.09; Fe the rest. The main difference of this alloy in comparison with analogs is a change in the Cr:Si ratio, which leads to the appearance of a certain amount of nodular graphite in the structure after modification. The structure of the developed alloy is represented by a ledeburite matrix, carbides and nodular graphite in the amount of 4 – 6%, which leads to an increase in the resistance to abrasive wear. The introduction of titanium carbide helps to simplify the shape of the primary graphite and to intensify the process of subsequent spheroidization. The proposed alloy has increased resistance to abrasive wear by 20 – 25% higher than Nihard 2. An application for a patent of the Republic of Kazakhstan has been filed for this composition.
The proposed composition of the cold-hardening mixture including, wt%: 3-5 phosphoric acid; 2-10 highly dispersed filler (dust from gas cleaning in the production of ferrosilicon); 4-6.6 water and quartz sand. The proposed mixture is characterized by high strength and vitality. The molds obtained from the proposed mixture make it possible to obtain castings from chromium-nickel cast irons of high precision and surface cleanliness. A patent of the Republic of Kazakhstan for a utility model was obtained for this composition.
A mode of processing (modification) is proposed, which consists in introducing a complex modifier based on ferrosilicon with magnesium and a composition of rare earth metals with a dispersion of 0.5-2 mm in an amount of 0.5-1%. The treatment with this modifier in the specified amount promotes the formation of nodular graphite with an average inclusion diameter of 35-40 microns, which provides an increase in wear resistance by 20 – 25% compared to Nihard 2.

The applied aspects of competence possession have been developed reflecting the linguistic abilities of a specialist with the use of modern information technologies.
Experimental studies have been carried out to identify communicative defects in oral spontaneous speech among bachelor, master and doctoral students of Karaganda Technical University and the Peoples’ Friendship University of Russia (Moscow).
A linguo-mathematical model has been developed to identify communicative defects in oral speech based on the Shannon law of conservation of the sum of information and entropy. For the first time, on the basis of the fundamental law of conservation of the sum of information and entropy, individual emotional and motivational processes of human speech activity will be identified on the basis of computer technologies.
The developed automated information system will allow checking the language readiness of specialists to identify the indicator of speech diagnostics in various communicative situations.

Information for potential consumers
The theoretical provisions and practical results can be used in training courses on the language theory, special courses in mathematical linguistics, the information theory, and the theory of speech communication.
The theoretical and further studies and practical results obtained within the framework of the project, as well as the experience accumulated by the project participants, allow moving onto a new stage of research: the development of private models that help to reveal the mechanism of the linguistic units functioning in speech.
The results of the project will make it possible to apply qualitative and quantitative assessments of the perception of the level of speech competence.

Relevance
The results of the studies carried out show that in the conditions of machine-building enterprises in Kazakhstan, more than half of the parts undergoing machining belong to the parts of bodies of revolution or have arcuate outer surfaces that are machined by turning. It has also been found that during turning there are problems of ensuring the accuracy and quality of turning associated with chip crushing, the occurrence of an impact load on the cutter. These disadvantages also lead to reduced productivity and tool life.
Conventional cutting of high-strength steels is characterized by extremely low plastic deformation during chip formation. There is usually no build-up when machining these materials. For these reasons, tool wear is very intense and occurs primarily along the flank surface. To solve this problem, a technology is proposed for turning parts of bodies of revolution by the method of thermo-friction milling.
The project purpose
Improving the productivity, accuracy and quality of machining parts of bodies of revolution.
Expected and achieved results
Working drawings of parts (an intermediate shaft, half-couplings, a cover, a support bracket, a plate, a rubber elastic element) and assembly drawing of the milling device were developed.
Technological processes of machining parts and the technological scheme for assembling a device for milling were developed.
On the basis of the design documentation developed at the previous stage of the project and procured through grant financing of consumables and equipment, parts and assemblies of a prototype of a special device were manufactured, such as: an intermediate shaft, a base plate, a support bracket, couplings, elastic elements. For further testing the device and implementing the technology of thermo-friction milling, tools and tooling were designed and manufactured, in particular, a friction cutter.
A prototype of a special device for a lathe was assembled in the KTU laboratory.
