Abstract. In this article, the technology of salt bath carburizing at low temperature (640 C) is used to prepare the titanium carbide thin film on Ti6Al4V alloy surface. The processed alloy sample surface phase and elements are observed by XRD and EDAX. The hardness of sample surface and permeability layer are measured by the MH-3 type microhardness meter. And the friction and wear contrast tests of the uncarburized and carburized samples are carried out using the M2000 friction and wear testing machine. The results show that: high hard phase carbide Ti8C5 is generated on the sample surface. The processed sample surface hardness is 953.28HV, which is 2.57 times of the original; The friction and wear properties of the carburized sample improve significantly; At 100 N, the uncarburzed wearing loss is 29 times of the carburized wearing loss, and at 300 N, the friction coefficient is reduced by 55.9 %.

Keywords: Ti6Al4V, salt bath carburizing, Ti8C5, friction and wear.
