Research progress on laser surface modification of metallic materials and laser rapid forming of high performance metallic components

Progress of research and applications on laser surface modifications (laser surface alloying, laser cladding) of advanced aeronautical metallic materials and laser rapid forming of high-performance metallic component currently undertaken in the Laboratory of Laser Materials Processing and Surface Engineering was reviewed and the potential applications in the aircraft and gas turbine engines were prospected. The main contents include (1) laser surface alloying and laser cladding of titanium alloys for wear-resistance, oxidation-resistance and burn-resistance; (2) laser cladding for advanced high-temperature self-lubrication wear-resistant metal and ceramic matrix composite coatings for high-temperature brush seal and finger-tip seal applications; (3) microstructure and mechanical properties of laser clad advanced high-temperature wear-resistant corrosion-resistant multi functional refractory metallic silicide composite coatings and processing; (4) laser rapid forming of high-performance/functionally graded titanium and superalloy components.
