Influence of layer-by-layer laser sintering conditions on the quality of sintered surface layer of products

[摘要] The influence of technological modes of sintering: the displacement velocity of laser beam V, laser power P, scanning step S and preheating temperature of powder material t on the quality of sintered surface layer of aluminum powder PA-4, copper powder PMS-1 and cobalt- chromium-molybdenum powder DSK-F75 were studied.
