Research on Laser Plating Technique and Charaterisitcs for High Speed Steel Cutters

This paper expounds the feasibility and practicality of laser plating technique for high speed steel cutter, researches systematically on form structure. thickness, microhardness and wear- resistance of the plated layer. Experimental results show that laser plating technique for high speed steel cutter posseses features of convenience, flexibility in application. Characteristics of the plated cutter are obviously improved. Its form structure is better than that before plating. The service life is three times higher than that of the unplated cutter.
