| Abstract Scope |
After long studies on bulk ceramic materials: Zirconia, Apatite, etc. to overcome their intrinsic brittleness, we have considered Coatings of ceramics film(s) on metallic alloys, etc. In 2008 we proposed a novel concept and technology of “Growing Integration Layer” [GIL] method, where GIL can be prepared via integration of ceramic film formation from a component of the alloys 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 Integration so-called Layer-by-Layer [LBL] strategy, deposited via Top-by-top.
On a Ti-base Bulk Metallic Glass, bioactive titanate nano-mesh layer was prepared by hydrothermal-electrochemical techniques at 90-120℃.The GIL method is suitable for wide variety of applications; bio- medical coating, thermal barrier, mechanical parts, environmental and/or chemical coating, conducting and/or insulating films, etc., Particularly, GIL Bio-active coating on alloys would be one of the best examples. We have also prepared HAP containing layers on Ti alloys. |
