The effective technologies for restoring the operability of shaft and bushing type parts depending on the nature of the damage to the working surface are considered. The most appropriate and environmentally friendly solutions in this area are identified from the standpoint of the possibility of their implementation in the conditions of repair production. It is shown that one of the ways to increase the resource of shafts and bushings during repair is to restore the surfaces by electrocontact sintering of powder compositions and form a favorable surface microprofile, providing better operating conditions for the tribo unit.
