Dip Coating of Calcium Hydroxyapatite on Ti‐6Al‐4V Substrates

Abstract

Ti‐6Al‐4V alloy is the most commonly used metallic material in the manufacture of orthopedic implants. The main inorganic phase of human bone is calcium hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 , HA). To achieve better biocompatibility with bone, metal implants made of Ti‐6Al‐4V are often coated with bioceramics. Dip‐coating techniques scarcely are used to apply HA onto metallic implants. New dipping‐solution recipes to be used for HA coatings are described in this work. Scanning electron microscopy and X‐ray diffractometry have been used for sample characterization.
