Abstract:A codeposition of bioglass (BG) and hydroxyapatite (HA) on the substrate Ti6Al4Vis realized in a nonaqueous solution system by inducing crystallization of HA on surface of the BG grain and electrophoresis deposition (EPD), and then a bioactive graded ceramic coating was obtained after sintering of the coating. This technique is a new method for making bioactive graded coating. The adhesive strength between the coating and the substrate reaches 18MPa, and the better electrophoresis depositing parameters and optimal sintering procedure are obtained.
Key words: hydroxyapatite; bioglass; electrophoresis deposition; graded coating; titanium alloy
