摘要：
A nozzle for processing machinery, wherein a hard ceramics coating is formed on the surface of the base metal of the nozzle for processing the machinery to prolong the service life thereof. Since the hard ceramics coating is formed on the surface of the base metal of the nozzle for the processing machinery, the nozzle for processing the machinery is hard to be scratched on the surface thereof and highly resistant to heat. Thus, service life can be prevented from being shortened due to the occurrence of scratch by the contact thereof with a warped work during processing and the deformation thereof by heat in the nozzle for processing the machinery to realize an increased service life.
