| Abstract: | In this paper, the experimental procedures are presented for Nitro-Boroconizing alloying treatment of gray cast iron surface using a CW COt laser with an output power of 500-2000 W modulated CW. We also give a analysis of the phase structure,the phase morphology ,the distribution profile of the hardness and the resistance to Abrasion of the sample after laser treatment.The ezperimectal results indicate that the N-B laser alloying will give many strengthening effects on the base metal, so that the properties of gray cast iron surface will be greatly improved. |
