Abstract
Al2O3 coating was achieved on a stainless steel substrate by cathodic plasma liquid deposition (CPLD) technology. The effects of the Ar calcination on the structure, phase composition, morphology and anti-high temperature oxidation property of the ceramic coatings were studied. The results show that the ceramic coating by CPLD is mainly composed of γ-Al2O3 and α- Al2O3 , Fe in the substrate does not come into coating. Coating surface is coarse and porous, and Ar calcination is helpful to the transformation of γ-Al2O3to α-Al2O3. After calcintion, coating surface become more compact and thinner, and property of the anti-high temperature oxidation of the coatings is improved remarkably.
