Resource-saving technologies of derivatization of functional nanostructured coatings by high-speed application methods

The work objective is to study new application methods based on the resource-saving technologies for nanostructured coatings with different functionality. The main task of the work is investigating modern efficient methods to increase strength, corrosion resistance, and wearability. The subject of study is high-speed application methods for anti-corrosion and wear-resistant coatings that significantly improve the durability and reliability of products. Design, technological features, specifications, and a scope of applicability of various installation models for high-speed deposition methods, including a gas-plasma technique, are described. The analysis results of the basic physical, mechanical and performance properties of the coatings obtained with the compact high-performance process equipment are presented. As a result of this work, it is shown that coatings obtained by the high-speed methods, unlike the subsonic methods, are characterized by the high performance. The paper also presents perspectives for development of the processing methods of the multifunctional coating application, the improvement of equipment and materials. The data obtained can be used for designing processes of applying dense coatings of consistent quality on the complex products made from nearly all metals and alloys. The results obtained are applicable in the mechanical engineering, repair production, aviation, energy engineering, etc

Agricultural machine parts quality control by dynamic non-destructive methods

The problem of quality control of agricultural machinery parts by means of dynamic non-destructive methods of impact indentation of conical shape indenters is considered. Quality of the crucial parts is considered from the point of view of a set of mechanical characteristics that determine the strength, hardness, wear resistance and deformability. These characteristics must be known and be able to control on all the details promptly and accurately both in the manufacturing process and in operation. The mechanical characteristics of metals are stochastic in nature. For this purpose, an impact indentation device was developed, and the method based on probabilistic laws of dispersion of mechanical characteristics is obtained
