Structure,tribological properties,and the growth mechanism of in-situ generated TiC in titanium cermet
文献摘要:
Titanium cermet combining metallic toughness with ceramic wear resistance has been proven to be a potential candidate for implanted joint material.In this work,titanium cermet was synthesized by means of the elevated temperature solid carburizing technology.The Ti13Nb13Zr alloy surface was found to be converted into TiC ceramic layer combined with a carbon strengthened diffusion zone underneath.The overall thickness of the carburized region grew to about 100 μm after 120 min carburization at 1,500 K.In order to clarify the growth behaviors of TiC ceramic layer,a growth mechanism is proposed.At the beginning of carburizing process,carbonaceous gas decomposed from carburizer due to high temperature and then converted to free atomic carbons through reduction reaction.Then,in-situ generated TiC ceramic layer possessing certain thickness formed on the surface,meanwhile,the inner carbon diffusion zone also grew inwards due to physical diffusion of carbon,and finally forming a gradient carbon distribution.In addition,the tribological behaviors of the new materials were evaluated through reciprocating ball-on-plate sliding wear tests in bovine calf serum.Although there was an increase in friction coefficient,the wear rate decreased by 59.6%due to the formation of the wear-resistant TiC ceramic layer.The wear mechanisms evolved from severe abrasive wear for bare Ti13Nb13Zr alloy to mild adhesive wear for titanium cermet.
