Abstract
Five types of micro–dimples with different area densities and Si–DLC films were produced on the surface of Al2O3/Ni laminated composites. The friction properties and wear mechanisms in a water environment were studied. Results show that the method is effective in achieving composition–lubrication on the surface of laminated ceramics by laser texturing and magnetron sputtering. The synergy effect of micro–texture and films influence the tribological properties of Al2O3/Ni laminated composites. The friction coefficient can be reduced by nearly one order of magnitude from 0.51 to approximately 0.06, compared to the conventional Al2O3/Ni laminated composites.
