Recently, carburization has attracted extensive attention as surface stiffening processing of titanium. In this research, the influence of processing temperature of pure titanium by carburization was examined. As a result of the examination, the surface hardness was approximately increased firstly and then decreased with the processing temperature increasing. And the hardness of the diffusion layer reached to the maximum value was about 1052 HV when the processing temperature at 850°C. The wear depth and wear width reached the minimum value at 850°C. At different carburizing temperatures, the content of wear width and wear depth were 262 μm and 2.76 μm respectively. In summary, when the processing temperature at 850°C, the carburization of pure titanium can improve the comprehensive properties.
