Tribological characteristics of superhard materials cubic boron nitride

Abstract

Tribological characteristics of similar pairs of friction superhard materials, as well as friction pairs superhard material — hard alloy without lubricant and lubricated. It was found that the superhard materials have ultra high wear resistance in the corresponding pairs of friction without lubrication with grease. The coefficients of friction and wear are reduced with the introduction of lubricant. The friction pairs hexane-P—hexane-P introduction lubrication reduces the coefficient of friction of 7,6 times compared with the dry friction; in pairs friction superhard materials — hard alloy is exposed to greater wear carbide.
