Nine kinds of groove texture with different geometric parameters were machined on the surface of YG6 cemented carbide by femtosecond laser processing system. According to the friction coefficient and wear morphology of the cemented carbide block and zirconia ceramic ball

the friction reduction mechanism of the surface texture is analyzed by the friction and wear test combining with the furrow effect. The results indicate that textured surfaces with reasonable parameters have lower friction coefficient and better wear resistance than smooth surfaces. Surface texture affects the friction and wear behavior of the contact interface by storing abrasive debris and cutting hard points on the ceramic surface. The larger the width of the texture

the greater the cutting effect on the hard points and the storage effect on abrasive debris. The spacing of textures affects the friction reduction effect by affecting the density of textures.
