With the aim of reducing wear and prolonging working life of a mould die,laser texturing technology was applied to the surface of the mould die.In the experiment,a 200W lamp pumped Nd:YAG laser was adopted to process the mould die surface.Then the rule of the effect of laser parameters on the micro profile of the mould die was obtained after experiments.Finally,the expected profile was obtained.The surface hardness and metallographic structure were measured and analyzed.The results showed that the surface hardness of slight protuberance was improved 30%~40% compared with that of the substrate and the wear resistance of mould die was improved too.
