The Bioactivity of Gradient Composite Bioceramic Coating with Two Kinds of Rare Earth Oxide Fabricated by Wide Band Laser Cladding

Abstract:

To improve bioactivity of gradient bioceramic coating, the coating with two kinds of rare earth oxide was produced by wide band laser cladding technique. As the experimental results, whichadded0.6wt.% La₂O₃fixedly, and increased the addition amount of the CeO₂, when the addition of CeO₂fulfill 0.4wt.%, the amount of HA-β-TCP is the largest in this experiment. Soaking the specimens in SBF for 14 days, the coating blended 0.6wt% La₂O₃ and 0.4wt% CeO₂, then a great quantity of Ca-P white particles can be found on coating, which confirmation this bioceramic coating is of best bioactivity.
