Effect of Mixed Multiple Rare Earth Oxide on the Microstructure of Bioceramic Coating Prepared by Wide Band Laser Cladding

Abstract:

In order to researching the microstructure of bioceramic coating on the surface medical titanium alloy (Ti–6Al–4V), the gradient bioceramic coatings are fabricated by wide-band laser cladding. The influence of multiple rare earths oxide La₂O₃ and CeO₂ on microstructure of bioceramic coating were studied. The experimental results demonstrated that mixed La₂O₃ and CeO₂ have an effect on forming-ability of HA\β-TCP in bioceramic coating and also refined the grain of bioceramic coatings. The largest amount of HA\β-TCP is presented among all the groups when the contents of La₂O₃ and CeO₂ are 0.6wt.%, 0.4 wt.%, respectively.
