激光清理(lasercleaning)是近几十年来伴随着激光技术的发展而出现的一项新的表面处理技术。PROTAL(激光辅助热喷涂)工艺引入激光清理技术作为基材的预处理工序与后续的热喷涂工序同步进行,避免了传统的化学清洁和喷砂预处理带来的一些弊端,实现了热喷涂技术的连续生产,因此在工业界受到较大程度的关注。文中介绍了PROTAL工艺的实现手段,发展历程以及相关的技术原理,并展望了未来的技术发展方向。 Lasercleaning is a new surface treatment technology that has emerged with the development of laser technology in recent decades. PROTAL (laser assisted thermal spray) process to introduce laser cleaning technology as a substrate pretreatment process and follow-up thermal spraying process simultaneously, to avoid the traditional chemical cleaning and sandblasting pretreatment brought some drawbacks to achieve the thermal spraying Technology continuous production, so in the industrial sector by a greater degree of attention. This paper introduces the means of PROTAL process, the development process and related technical principles, and prospects the future direction of technology development.
