Abstract
Statement of the problem (relevance of the research). This paper is experimental research carried out in order to produce a composite antifriction material with increased heat resistance. For this purpose, a composite nickel-based, metal-glass material was produced. As you know, when developing powder composite antifriction materials, a special attention is paid to increasing wear resistance. However, many friction units are operated at elevated temperatures for a long period of time. When developing a material that works in such conditions, in addition to wear resistance, it is necessary to take into account the long-term resistance to elevated temperature. Methods applied. In the course of the study, we used the methods of powder metallurgy, including production of powder of broken container glass (BT-1), a two-component mixture consisting of glass powder and reduced nickel powder (PNK-UT3), molding by means of a hydraulic press and subsequent sintering in a protective reducing atmosphere of hydrogen. To determine the heat resistance, we used a gravimetric research method, involving an analytical balance. To get digital models of the dependence of heat resistance on the composition of the composite material, we applied STATISTICA 10, a mathematical analysis package. Novelty. Producing a composite material with increased heat resistance, where nickel powder was used as a matrix and container glass powder was used as a reinforcing element. Result. We studied and determined the dependence of heat resistance on the chemical composition of the composite material and the method of production. Practical significance. Development of a new material with improved performance characteristics and a potential subsequent implementation in production as a material for manufacturing plain bearings.
