【 摘 要 】

Experimental results on bioactive modified treatment at titanium alloy was presented. A better metallurgical bonding of the single tracks with the substrate was obtained by the use of laser beam via an integral mirror. The samples were studied by Scanning Electron Microscope (SEM), Inductively Coupled Plasma (ICP), microhardness instrumentation and corrosion resistance testing. The facts show a significant influence of microhardness on the optimized experimental condition. Furthermore, it reveals that a significant influence of property, especially for corrosion resistance while the rare earth oxide ceria is mixed in the precursor powders. The dynamic factor is a possible influence of escape of granules. The laser-cladded bioceramic coating of ceria additive in pre-placed powders has more favourable corrosion resistance compared with the coating without rare earth oxide.
