Wear Mechanics in High Speed Sliding Contact.

Abstract

The concept of hard particles generation and growth due to possible crystal transformation of layered type hexagonal structured materials such as graphite, molybdenum disulfide and boron nitride, at high temperatures, concomitant high pressure and in presence of a suitable catalyst-solvent material, in high speed sliding is introduced. The mechanism of galling of polyphase materials in high speed sliding contact based on continuous depletion of second phase strengthening carbides from the matrix is presented and verified experimentally. The mechanism of sphere formation of fine chips generated in high speed sliding based on curling of chips due to a bending moment and subsequent bonding of many such curved chips into a sphere due to the curved platelets being highly polarized, is presented and qualitatively verified experimentally.
