Abstract
The effect of tribological properties of laser-textured with different surface coverage and diameters on HA/ZrO2 coating is studied. Under the bovine serum lubrication conditions, the effect of load and speed on anti-friction mechanism is tested. Experiments show that the surface texture has an excellent morphology, its tribological property is significantly better than that of the un-textured coating, surface coverage 10%,Φ250μm coating showed the optimum tribological characteristics.
