SELF-LUBRICATING COMPOSITE MATERIAL, COATING, PHASE COMPOSITION, STRUCTURE, STRUCTURAL CONDITION, MECHANICAL PROPERTIES, SLIDING VELOCITY, PRESSURE, COEFFICIENT OF FRICTION, WEAR. The objects of research are tribotechnical composite materials and coatings based on iron The purpose of the work is to study the regularities of the formation of the tribosynthesis zone in composite materials based on metals and their coatings in the process of friction loading at high temperature. Synthesis of tribotechnical self-lubricating composite materials and coatings from them, which are intended for operation in air without lubricants with a low level of frictional losses at high (up to 500 degrees) ambient temperature; Research methods - metallographic, X-ray, tribotechnical testing of materials. The technological parameters of the synthesis of iron-based tribotechnical material for work at high temperature, and the dependence of tribotechnical characteristics of friction pairs on sliding speed and load, were determined. The phase composition and structural state of iron-based composite materials and secondary lubricating films were studied, as well as the interaction of the structural components of the iron-based composite material during sintering at a temperature of 1200 C. Tribotechnical self-lubricating iron-based composite materials and their coatings containing hard lubricant CaF2. Based on the research results, it was established that iron-based materials and coatings are promising as tribotechnical under conditions of elevated temperature and low sliding speed, when their coefficient of friction is 0.19-0.27, and wear is in the range of 2.2-6. 0 mg/km.   Product Description popup.authors Umanskyi Oleksandr P.
