【Abstract】 The tribology and wear characteristics and wear mechanism of lasertransformation hardened high speed steel M2 have been systematically studiedby means of wear tests in this paper.The experimental results show that thewear and scuffing resistances are considerably improved by laser transformationhardening compared with those conventionally heat treated due to the effectsof high hardness,strength and toughness.更多还原
