Paper Title:
Experiment Study on Tribological Properties of the Coating with Different Surface Textures
  Abstract

This paper is about the KF301/WS2 modified lubricating wear-resisting coating which is prepared by supersonic plasma spraying, laser remelting and surface texturing technology, tribological characteristic of KF301/WS2 lubricating wear-resisting coating of four different (round pit, diamond, parallel and intermittence) tracks and part laser remelting is studied under room temperature. Research shows: textures of different tracks have a certain influence on friction factor of coating’s surface and abrasion loss. Friction coefficient of mouldling surface of broken texture is about 0.012 in the initial stages, while friction coefficient of round pit texture is about 0.0085. Round pit, diamond and parallel microtopography make friction state enter stabilization quickly, effectively restraining the wave of abrasion loss. When wear time reaches to 1 hour, abrasion loss of broken texture is 0.03mg, while abrasion loss of round pit texture is about 0.015mg. Tribological properties, from high to low, in turn, are round pits, diamond, parallel and broken texture.
