View of improvement of Quality of life (QOL) for senior citizens, implant treatment that embed prosthesis into a living body has advanced as a method of treating for deterioration or a lesion part. Recently, addition of Hydroxyapatite (Ca10(PO4)6(OH)2, HAp) coatings onto titanium alloy has been developed to reduce duration of treatment and improve strength of treated part. However, adhesion property between such coatings / substrates isn't well known. The purpose of this study is to establish evaluation method of interfacial strength for such coatings system. In this study, plasma-sprayed HAp coating specimens were investigated by means of both tensile adhesion strength test and shear adhesion strength test. The influence of evaluation method and pre / post heat treatment on interfacial strength of plasma-sprayed HAp coating was discussed.
