Copper was diffused on the surface of titanium alloy Ti6Al4V by ion implantation, magnetron sputtering and double glow discharge plasma surface alloying technology respectively to form an alloy layer on the surface of titanium alloy in order to improve the burn-resistance performance of titanium alloy. The result of X-Ray Diffraction shows that the phase of CuTi2 which can improve the burn-resistance performance can be found on the surface of the samples treated by the above three methods. And femtosecond laser ablation experiments show that the burn-resistance property of the titanium alloy can be enhanced by ion implantation, but the alloyed layer is too thin to be applied in practice; both of alloy layer and film can be formed on the surface of titanium alloy by magnetron sputtering, the alloy layer takes evident effect on the burn-resistance properties of titanium alloy while the film has no effect on the burn-resistant properties; alloy layer with Cu can be found on the surface of titanium alloy by the double glow plasma surface alloying technology with the source of pure copper, and its effect on burn-resistance properties of the titanium alloy is evident as the scar area by the laser burning experiment has been reduced heavily.
