摘要
激光熔覆是一种新兴的材料表面技术,近年来得到了快速发展。激光熔覆层的质量受熔覆过程中多种因素的影响,其中熔池温度是一个非常关键的因素,激光熔覆熔池温度的监测与控制系统的研究对提高熔覆层质量具有重大意义。介绍了激光熔覆熔池温度的检测方法,综述了目前激光熔覆熔池温度控制系统的研究现状,并列举了部分温度控制系统。根据目前国内外的发展现状提出了熔池温度监测与控制系统的发展方向。
Laser cladding is a new surface technology that has been developed rapidly in recent years. The performance of laser cladding layer is influenced by various factors, among which temperature of molten pool is a key factor in particular. The temperature measurement and control of laser cladding molten pool play an important role in controlling the quality of laser cladding. We introduce the commonly used temperature measurement methods, and review the current research state in various control systems for molten pool temperature of laser cladding. Based on the review, the future development of temperature measurement and control is prospected.
