摘　　要：通过试验研究了等离子激光复合快速制造中激光对等离子弧柱形貌、熔积成形时的熔深和熔宽等的影响。试验结果表明:激光作用于等离子弧后,等离子弧柱的直径变小,挺度增加,稳定性增强,起弧容易,熔积层的熔深增大,熔宽减小。利用等离子激光复合熔积法可以快速成形高温合金及难熔材料。The effects of laser on plasma arc beam, welding depth and width of deposition pool in the hybrid plasma-laser rapid manufacturing is investigated by tests. The result shows that the diameter of plasma arc beam becomes smaller, the stiffness and the stability increase and arc starting is easier, the pool depth of the deposition layer increases and the pool width decreases after laser acts on plasma arc. Rapid manufacturing of the high temperature alloy and difficuh-meh materials can be carried out by using hybrid plasma-laser deposition manufacturing method.
