WORKING CAPACITY IMPROVING OF BEARING MATERIALS AT WORK WITHOUT LUBRICANT
The results of the experimental work on development a friction pair, which capable to work without lubricant with high parameter load and speed factor are presented. To increase the possible velocity of the slide and to provide the even of friction coefficient on measure of the wear-out worker layer of bearing materials is designed way of the making on steel substrate bronze-cermet coating, which has given (columnar) structure of porous layer. To increase the possible load a compositions to complex borate steel counterbody, which are working in pair with bearing material, is designed. They allow to get a covering thickness before 1 mm with high striking viscosity, hardness and wear resistance.
