Friction and wear on hard alloy coatings of the Cr 3 C 2 –Ti system over silicified graphite in water

Abstract

Establishing basic friction parameters of new hard alloys to be used for the fabrication of sliding weight-bearing components that work in conjunction with silicified graphite in water lubrication is an important task. Completing this task will help determine principles for selecting a tailored arrangement of components to comply with the operational conditions of the friction pair. The antifriction properties and durability of chromium carbide hard alloys during sliding friction over silicified graphite in water are conditions generated by alloy hardness and chromium carbide volume fraction in the material structure. The wear of a friction pair may be reduced by one order of magnitude if explosively pressed chromium carbide and titanium-based alloys replace such traditional materials as silicified graphite or hard alloys of chromium carbide with nickel.
