Ultrasonic vibration-assisted laser cladding (ULC)

based on the advantages of efficient surface modification and forming of laser cladding

applies ultrasonic energy field to overcome the defects caused by rapid solidification. ULC has become a research hotspot at home and abroad. The research shows that after the application of ultrasonic vibration

the grains of the laser cladding layer are refined and equiaxed grains are able to be formed. Meanwhile

the microcracks and porosity defects are significantly inhibited

and the hardness

wear resistance and oxidation resistance are improved. Combined with the research results of our group in the field of ULC and considering the characteristics of ultrasonic vibration

the research status of ULC technology at home and abroad is reviewed. The principle of ULC technology

the ultrasonic vibration device and ultrasonic applying mode in ULC technology

the microstructure characteristics and performance of ULC cladding layer are analyzed emphatically. Furthermore

the application of ULC technology is prospected.
