<p>The two major difficulties associated with Ti6Al4V (Ti64) are: (i) they are hard to cut/machine through conventional approaches, and (ii) they have highly unstable tribo-behavior. The current investigation adopts the powder mixed electrical discharge coating (PMEDC) route to fabricate/deposit hard and self-lubricating layers to investigate the sliding wear characteristics of the modified Ti64 surfaces under dry condition. Dielectrics suspended with SiC and graphite powders were used to assist the process. The former aided in the evolution of carbides (TiC) and silicides (Ti₅Si₃), imparting high hardness to the substrate. Tribo-adaptiveness exhibited by the surface layers undergoes deterioration at high load conditions due to material pull-out and abrasive action of the secondary phases. Abrasion was the dominant wear mechanism. For the latter, the surface appendage layer consists of graphite and graphite oxide (GRO). The ability of these components to exhibit self-lubrication/lubricity characteristics enabled the surface layer deposition to demonstrate superior wear resistance. Transition in wear mechanism occurred in the context of bare Ti64 (abrasion to delamination) and for surfaces modified through PMEDC assisted by graphite suspended dielectric (abrasion dominant to adhesion dominant), with increment in sliding velocity and load conditions.</p>
