Abstract
Extreme high-speed laser cladding technique is a newly-developed surface coating technology,which can be used to prepare dense protective coatings with a metallurgical bonding interface.Compared with the traditional cladding,extreme high-speed laser cladding technique has higher processing efficiency,and the prepared coatings possess much lower dilution and finer microstructure.Thus,extreme high-speed laser cladding coatings show superior protective service performance,which makes them more promising to be applied in industrial production.The fundamental principle and advantage of the extreme high-speed laser cladding technique were introduced,and the development status of the processing equipment in China and abroad were summarized.Furthermore,the current research progress and problems of extreme high-speed laser cladding coating materials were summarized and discussed.As last,the development trend of extreme high-speed laser cladding technology and corresponding coating materials was forecasted.
