摘要：

A novel electrochemical co-deposition approach was developed to prepare hybrid bioceramic coating of hydroxyapatite (HA)/poly(vinyl acetate) on the surface of Ti-6Al-4V alloy. The aim is to improve the adhesion between the HA coating and the metal substrate. Surface characterization showed that the composition of inorganic phase in the composite bioceramic coatings was mainly HA and the content of organic phase was more than 4% (W/W). Significant surface morphology changes were observed. The shear-testing experiments indicated that the bonding strength of the hybrid coating to metal substrate was increased by as much as 3 MPa.
