摘要

In order to achieve the prolonged life of the processing machine nozzle 10, to form a coating (2) of hard ceramic to a metal base material (1) the surface of the processing machine nozzle 10. By forming the film (2) of hard ceramic to a metal base material (1) the surface of the processing machine nozzle 10, a nozzle processing machine 10 is difficult to be strong heat smoking scratch the surface.
