摘      要：Microporous titanium carbide coating was successfully synthesized on medical grade titanium alloy by using sequential *** in the surface morphology of titanium alloy occasioned by sequential carburization were characterized and the wettability characteristics were ***,the dispersion forces were calculated and *** results indicate that sequential carburization is an effective way to modify the wettability of titanium *** the carburization the surface dispersion force of titanium alloy increased from 76.5×10^(-3)J·m^(-2) to 105.5×10^(-3) J·m^(-2),with an enhancement of 37.9 %.Meanwhile the contact angle of titanium alloy decreased from 83° to 71.5°,indicating a significant improvement of wettability,which is much closer to the optimal water contact angle for cell adhesion of 70°.
