COMPOSITE self-lubricating antifriction material based on copper for operation in vacuum at LOW TEMPERATURES

摘要

The invention relates to the field of nonferrous metallurgy in particular, to self-lubricated antifriction composite material based on copper for operation in vacuum at low temperatures and can be used in space technology for the production of sliding bearings of mechanisms and aggregates of planetary space complexes in instrument making, mechanical engineering and power-engineering for manufacture of friction bearings, liners, rotating joints etc. This material contains the ingredients in the following ratio, wt. %:The invention provides a lowering of friction coefficient and wear intensity in vacuum of 1.510of mercury at a temperature of in 1.4 and 3.0 times, respectively.
