Developing a mechanochemical surface pretreatment to increase the adhesion strength of hydroxyapatite electrophoretic coating on the NiTi alloy as a bone implant

In this work, the pretreatments of sandblasting for 5, 15, 20, and 30 s followed by acid-etching were conducted to improve the adhesion strength amid the NiTi substrate and an electrophoretic coating of hydroxyapatite as a bone implant. The composition, microstructure, and surface topography of mate...
