To improve the tribological properties of titanium alloy at elevated temperatures, a multilayered lubricating coating was fabricated on the surface of Ti6Al4V alloy, involving an oxide ceramic coating deposited by PEO treatment, an electroplating Ag coating and a burnished MoS 2 film. The tribological properties were evaluated by a ball-on-disk high temperature tribometer over a wide temperature range (RT-600 °C). The results showed that the low friction coefficient and high wear resistance were exhibited at room and medium temperatures (< 350 °C) due to the effective lubrication of MoS 2 and Ag layers and the high load supports provided by hard PEO coating. At high temperatures (> 350 °C), the oxidation of MoS 2 topcoats and the adhesive wear of softened Ag led to the direct contact of Si 3 N 4 /exposed oxide underlayer giving rise to the rapid increase of friction coefficient. As the temperature increased to 600 °C, the friction coefficient sharply decreased to a low level ~ 0.2, which was attributed to a combined effect of the diffused Ag from discharged reservoirs, the presence of high temperature lubricants (MoO x , Ag 2 MoO 4 ) and the formation of lubricants/lubricating glaze layers contact.
