A SYSTEMATIC APPROACH TO THE SELECTION OF TECHNOLOGIES FOR CONTROLLING THE QUALITY PARAMETERS OF THE SURFACE LAYERS OF MACHINE PARTS WORKING IN CONDITIONS OF HYDROABRASIVE WEAR
Abstract
In the actual work, attention is paid to the fact that the wear resistance of parts is affected by their working conditions and material parameters, such as hardness and microstructure, as well as the quality parameters of their surface layers, which can be controlled thanks to the existing range of technological methods. The effective life of the equipment depends on the bearing capacity of the surface layer of the parts, which is determined by its quality. It has been proven that the works that connect the parameters of the main material of the part and the quality parameters of their surface layers with resistance to wear are relevant and timely. The purpose of the work is to increase the reliability and durability of machine parts operating under hydroabrasive wear conditions by developing a systematic approach to the selection of technologies for controlling the quality parameters of the surface layers of their parts. The methodology of targeted selection of technology for improving the quality of surface layers of products covers its entire life cycle, which includes: the material of the product and its elements, the technology of manufacturing the product and its elements, the technology of repair and restoration of operability, etc. All of them are considered through the special methods of directed selection mentioned above. At the same time, it is necessary to take into account the influence of the chosen methods on each other, which will ultimately affect the quality of the product. The very method of system analysis can be traced in this interpretation. On the basis of theoretical research, the authors improved the interdependence of the information sphere, which consists of scientific and technical preparation of production: design, technological, organizational and scientific research work, and the material sphere, which includes: production, operation, repair and disposal. A system of targeted selection of an environmentally safe technology for managing the quality parameters of the surface layers of parts of machines operating in conditions of hydroabrasive wear has also been developed. It is noted that when it is necessary to solve optimization tasks related to the choice of an environmentally safe technology for managing the quality parameters of the surface layers of machine parts operating in conditions of hydroabrasive wear, the role of the information sphere, which consists of the results of knowledge expressed in laws, theories, is significantly increasing, scientific hypotheses. Thanks to the information sphere, such forms and means as an idea, problem, hypothesis, concept, law, theory are created and acquire relative independence.
