CERAMIC LAYER COATING METHOD ON THE METALLIC SUBSTRATES SURFACE USING ION BEAM MIXING

摘要

A method of coating a ceramic layer on a metallic material surface using the ion beam mixing is provided to improve the corrosion resistance and the thermal stress by forming a new mesopause at a boundary face between the ceramic coated layer and the metallic material. A method of coating a ceramic layer on a metallic material surface using the ion beam mixing comprises followings. The electronic beam is irradiated and the ceramic coating material is vaporized with melting. The molted and vaporized ceramic coating material is coated on the metallic material. The ion beam is irradiated in interface between the coated ceramic coating layer and the metallic material to mix the mesopause. The metallic material and the ceramic coating layer in which interface is mixed are heat-treated and to form the new mesophase. Coating of the ceramic coating material on the metallic material is performed with the physical vapor deposition. The physical vapor deposition comprises the sputtering method or the electron-beam evaporation The metal material with a superior metallic material is the mechanical property in the 300~900°C. The ceramic coating layer thickness coated on the metallic material is 100~200Å.
