Gradient Coating

To improve bonding strength between titanium alloy and coating and to eliminate thermal stress during laser cladding, a gradient coating materials is designed. And the gradient coating with different contents of multiple rare earth deoxide was produced by wide band laser cladding technique. The experimental results indicate that when addition of Sm2O3 is fixed to 0.3wt.%, as addition of Y2O3 increases, the microstructure of bioceramic is different. When addition of Y2O3 reaches 0.4wt.%, the amount of Ca-P based bioactive phases such as HA, α-TCP as well as β-TCP becomes biggest. After soaking the coating with 0.3wt.% Sm2O3 and 0.4wt.% Y2O3 in SBF for 14 days, a large amount of Ca-P white spherical particles can be observed on coating, which demonstrates the bioceramic coating is of best bioactivity.

Common Problems

In this paper, the common problems of the preparation of hydroxyapatite (HA) bioactive coating on the surface of titanium and titanium alloy were described, which included bonding strength and biological activity. The improvement of the bonding strength between coating and matrix could be reached by using proper preparation method and changing the composition and structure of the coating. Besides, in order to improve the biological activity, micro regulation of three factors including the roughness, porosity and crystallinity of the coating surface could been used.
