| Abstract: | The process and effect on graded hardmetals with cubic rich surface was reviewed.The effect of composition,temperature and nitrogen presser on the surface nitrogen potential and microstructure was discussed with emphasis.Increasing Ti content and nitrogen pressure was conducive to the formation of graded surface.The temperature should be determined from composition of the alloys. |
