主 题：Selective laser melting Tungsten Laser power Scan rate Thin wall part Surface morphology
摘 要：The tungsten thin wall parts which were used as high-performance collimator devices were fabricated by optimizing selective laser melting laser *** effect of laser power and scan rate on wall thickness and surface morphology of tungsten山in wall parts was investigated,*** results indicated that the wall thickness increased with the enhancemem in laser power as a linear *** the contrary,the wall thickness decayed exponentially with the acceleration in laser sean ***,the wall thickness of the parts fabricated by laser double-pass melting was ihinner than that fabricated by laser single-pass *** addition,mathematic models for selecting suitable laser power and laser sean rate to fabricate specified tungsten thin wall parts were ***,the effects of laser parameters on the top surface roughness,adhesive parts and hot cracks were also discussed.
