解读金属材料表面工程的应用与发展(5)

superconducting thin film is polycrystalline or epitaxial single crystal films, resistance to high temperature and high power semiconductor diamond film and a variety of electronic thin films and integrated optical thin film. Aluminum and its alloy surface modification techniques mostly used is the appearance of film composition skills, high functional film wear and corrosion resistance, porous, with strong in appearance. Skills change the aluminum alloy surface mainly has: the electrochemical oxidation, chemical transformation, micro-arc oxidation, plasma surface modification of writing skills, cold spraying skills, rare earth conversion coating and laser treatment. High energy beam surface modification technique, high energy beam surface modification technique is the use of high energy beam source, increase with or without the addition of chemical elements, remelting and cladding treatment on material surface and sub surface.
