Abstract:
A ceramic plating process, comprising the steps of:ejecting ceramic particles onto a surface of a workpiece comprising a metal or a metal component by blasting, the ejection of the ceramic particles by blasting for generating a local rise in temperature in the workpiece such that the ceramic particles are dispersed into the workpiece and for reducing a thermal conductivity of the surface of the workpiece; andsubsequently ejecting a coating consisting essentially of a metal powder thereon by blasting,wherein when the coating metal powder is ejected on the workpiece with said reduced thermal conductivity, a resultant increase in temperature is concentrated on the coating metal powder and the surface of the workpiece, so as to cause elements in the composition of the coating metal powder to diffuse and penetrate inside/onto a ceramic particle dispersed layer on the surface of the workpiece previously treated with ceramic particles by blasting.
