In this study, MAO coatings were fabricated on Ti6Al4V surface, and modified graphene was used as an oil additive, which effectively enhanced the tribological properties and reduced the friction coefficients. The friction coefficient of Ti6Al4V lubricated with modified oil was lower than that of Ti6Al4V lubricated with PAO-MGr synthetic oils.
In this study, micro-arc oxidation (MAO) coatings were fabricated and modified graphene (MGr) was used as an oil additive to enhance the tribological properties of Ti6Al4V. The results show that: the friction coefficient of Ti6Al4V is significantly reduced when lubricated by the modified oil, and the friction coefficients of the MAO coatings are much lower than those of Ti6Al4V with Poly alpha olefin synthetic oils that are added with modified graphene (PAO-MGr). The mainly wear form of Ti6Al4V is mainly adhesive, while that of the MAO coating is abrasive. Furthermore, the peaks of typical graphene were observed in the friction region using Raman spec-troscopy. The modified graphene enters the porous structure of the MAO coating and forms a stable graphene transfer film, thereby achieving a low friction coefficient and wear.
