We have proposed a novel concept and technology of the formation “Growing Integration Layer” [GIL] method,where GIL(s) can be prepared via integration of ceramic film formation from a component of the metallic materials by chemical and /or electrochemical reactions in a solution at low temperature of RT-200℃. They have particular features:1)Widely diffused interface(s),2)Continuously graded layers grown from the bulk(substrate),3)Low temperature process,etc. They are quite different from Layer-by-Layer[LBL] strategy,where every layer is deposited from the Top. BaTiO3 or SrTiO3/TiOx GIL films on Ti plates formed by hydrothermal-electrochemical method showed good adhesion. CaTiO3/Al2O3/Ti2Al GIL films on TiAl exhibited excellent adhesion and anti-oxidation performances. On a Ti-base Bulk Metallic Glass, we could succeed to prepare bioactive titanate nano-mesh layer by hydrothermal-electrochemical techniques at 90-120℃.
