The Influence of Rhombus Cross Track Laser Remelting on Tribological Properties of Lubricating Wear-resisting Coating Prepared Plasma Spraying

摘要

This paper is about the KF301/WS2 lubricating wear-resisting coating of diamond textured surface modification which is prepared by supersonic plasma spraying,laser remelting coating and surface micro moulding,and coating's tribological characteristic is studied under room temperature.It indicates that the diamond texture has a certain influence on abrasion loss and friction factor of coating's surface.In the initial stages,fiction coefficient of untextured surface is about 0.0138,while fiction coefficient of textured surface is about 0.0115,compared with the former,the latter is obviously better and decreases 17％; When wear time reaches to 1 hour,abrasion loss of untextured surface is 0.03mg,and which of diamond textured surface is about 0.018,compared with the former,the latter is obviously better and decreases 40％.Tribological characteristic of diamond textured surface is higher than untextured surface.
