| Abstract Scope |
Ti-6Al-4V alloys are applied in many industries due to their high strength, low density, and good corrosion resistance. To improve the wear performance of Ti-6Al-4V, five different surface modifications were performed: single-step oxidation, two-step oxidation + reduction, three-step oxidation + reduction + reoxidation, oxidation at reduced oxygen partial pressure, and a newly developed Zr slurry diffusion coating followed by subsequent oxidation to form ZrO2-enriched TiO2 on the surface. Dry sliding wear tests were carried out using a Si3N4 counterpart with a load of 5 N for a total sliding distance of 300 m. Deep ploughing grooves were not evident in the wear tracks of any surface-modified Ti-6Al-4V materials. Instead, wear debris containing Si-rich oxides formed as a tribolayer for most modifications. All surface treatments led to narrower and shallower wear tracks and no material removal was detectable for the Zr diffusion-coated sample under the investigated conditions. |
