Research progress of extreme high-speed laser coating technology and its novel coating materials
摘要
Abstract
Extreme high-speed laser coating technology has emerged as a key technique for fabricating a new generation of high-performance surface coatings,thanks to its ultra-high processing efficiency,low heat input,and excellent metallurgical bonding characteristics with the substrate.Compared with conventional laser cladding,this technology can significantly suppress defects such as pores and cracks,and produce coatings with dense microstructure and superior performance,thus demonstrating enormous application potential in the fields of remanufacturing and surface strengthening of key components for high-end equipment.This paper elaborates on the technical principles and core advantages of extreme high-speed laser coating technology,focusing on the analysis of the influence rules of key process parameters including laser power,scanning speed,and powder feeding rate on the surface quality and microstructure of new material coatings prepared by this technology.It also summarizes the recent research progress on new cladding materials such as amorphous alloys,ceramics,composite materials,and high-entropy alloys,as well as the current limitations of these new cladding materials and the problems to be solved in the future.Finally,this paper concludes the research progress of extreme high-speed laser coating technology in terms of process optimization,new material development,and research method innovation.关键词
