摘要:在激光熔覆过程中,温度是影响熔覆层质量及熔覆效率的主要因素。现有的温度控制方法主要通过调整工艺参数、物理冷却熔覆头喷嘴等方式实现,普遍存在熔覆效率低和温度控制效果差等问题。本文提出了通过冷却装置实现对基板或工件进行物理冷却的温度控制新方法,该装置可有效控制熔覆温度,提高激光熔覆质量及效率。

Abstract:In laser cladding process,temperature is the main factor affecting the quality and efficiency of cladding.The existing temperature control methods are mainly realized by means of process parameter adjustment,physical cooling of the cladding nozzle and so on,resulting in such problems as low efficiency and poor temperature control.A novel temperature control method is proposed through applying the proposed cooling device to physically cool the substrates or workpieces.The device can effectively control the cladding temperature and improve the quality and efficiency of laser cladding.
