Abstract:

In the work it is considered tribotechnical parameters of materials depending on sliding speed at the normal temperatures. The relationship of intensity of wear depends on mechanical characteristics of material is determined. It is investigated the tribotechnical characteristics of concrete materials, the diagrams of intensity of friction and wear depending on the sliding speed of pluraly tungsten and its alloy are constructed. Results of a research can be useful for developing and operation of themachines and equipment used in the oil and gas industry.

Keywords: piston machine; materials; mechanical properties; tribotechnics; friction and wear.
