Abstract
High Current Pulsed Electron Beam (HCPEB) was employed to treat Ti-6Al-4V alloy subjected to micro-arc oxidation. The surface morphology and phase composition of surface film were investigated, as well as the wear and corrosion resistance. The results show that the coarse porous ceramic coating becomes smooth and compact after electron beam treatment. High temperature stable rutile phase increases, and low temperature stable anatase phase reduces. The friction coefficient of composite coating reduces obviously and stabilizes at 0.2, and the wear resistance is improved. The increased corrosion potential and decreased corrosion rate exhibits an enhanced corrosion resistance.
