摘　　要：采用基于匀质化理论的宏细观连成温度场计算数学模型 ,模拟了等离子熔射过程中皮膜生长过程及其温度场 ,并采用不同的喷枪运动速率研究其对熔射中皮膜生长过程温度场的影响 。The homogenization theory was used to establish the mathematic model for the temperature field on macro-micro scale, and various scanning speed was applied to the RPST. The coating growth and the temperature field of the coating were simulated and various corresponding temperature fields were discussed to obtain good coating by applying a reasonable scanning speed.

关 键 词：等离子熔射 匀质化理论 喷枪运动速率 温度场
