摘要: This paper reports a wear reduction by up to six orders of magnitude for Ti-6Al-4V alloy when treated an oxygen diffusion (OD) process and subsequently tested in zinc-dialkyl-dithiophosphate (ZDDP)-containing lubricant. In addition case hardening, it is discovered that OD enables the formation anti-wear boundary film on titanium surface. Transmission electron microscopy surface chemical analyses revealed this has two-layer structure comprising amorphous oxide interlayer ZDDP-based top with complex compounds.
