Project abstract:

This program is aimed at the development of resource-saving technology of supersonic arc metallization for strengthening and restoration of working bodies of soil tillage machines. The working bodies of agricultural machinery work in difficult conditions, such as fields with uneven relief, uneven surface and different weather conditions. The availability of reliable and durable working soil tillage machines plays a crucial role in agricultural operations, especially in preparing the soil for planting crops. One of the ways to increase the service life of working bodies of soil tillage machines is to apply wear-resistant coatings on wear surfaces. This not only increases their durability, but also ensures stable and efficient operation in the field.

Among the various thermal spraying methods, wire-arc spraying, also called arc spraying (AS), is widely used in the repair and restoration of structural parts in the engineering, mining and energy industries. Compared to other thermal spraying methods such as High Velocity Oxygen Fusion (HVOF) and Atmospheric Plasma Spraying (APS), Arc Spraying is preferred due to its relatively lower cost, ease of maintenance, higher spraying productivity and significant economic advantages for large area spraying.

Practical significance of the project is that the project results will ensure the development of supersonic arc metallization technology and its wide introduction in the agricultural industry of Kazakhstan. Wider introduction of complex technological, design and organizational measures aimed at hardening and restoration of worn parts will provide an opportunity to obtain a significant economic effect by extending the resource of products, reducing the volume of spare parts, reducing the cost of metallurgical cycle of production, reducing the cost of raw materials, energy and labor resources.

The socio-economic effect should include the fact that hardening and increasing the wear resistance of soil tillage machine parts not only increases the resource of parts and thus reduces metal consumption, but also ensures the productivity of agricultural enterprises. In addition, active participation in the implementation of this program of masters, doctoral students and young scientists will contribute to increasing the level of knowledge and experience in research work of the young generation of scientists and training of highly qualified personnel in the field of materials science.

Goal:

Development and implementation of supersonic arc metallization technology to improve the complex of mechanical, corrosion and tribological characteristics of agricultural machinery parts.
