Abstract

An analysis of the existing anti-friction materials used in the friction units of the gas pumping unit as bearing liners was carried out. Taking into account the shortcomings, a new material is proposed in the work, which will be cheaper and have better operational properties. It was considered the characteristics of effect of alloying of metallic die on the processes of generation of tribotechnical characteristics of alloys and coatings on the basis of iron with refractory carbides and borides. It was resulted the technology of alloying of die of eutectic alloys as VTN by the components of bronze Sn-Zn-Pb 5-5-5. It was designed a wearproof antifriction eutectic alloy on the basis of iron for the welding of surfaces of  bearing shells, presented it’s tribotechnical characteristics and estimated the perspective of using the alloy for shells of sleeve bearings of gas turbine units in place of babbits.
