热氧化工艺对Ti6Al4V钛合金组织和摩擦性能的影响
Effects of thermal oxidation process on the microstructure and friction properties of Ti6Al4V titanium alloy
摘要
Abstract
In an air environment,surface modification of Ti6Al4V titanium alloy was performed by controlling thermal oxidation temperature and time.The microstructure,phase composition,Vickers hardness,and dry tribological behavior of the thermally oxidized Ti6Al4V alloy were characterized using X-ray diffractometer,scanning electron microscope,microhardness tester,and friction and wear testing machine.Results show that thermal oxidation significantly affects the microstructure and tribological properties of Ti6Al4V titanium alloy.When oxidized at 650 ℃ for 10 h,the sample exhibited the densest surface and highest Vickers hardness.Under this condition,the wear track depth was reduced,the wear scar morphology was optimized,and the wear rate decreased significantly.Compared with the non-thermally oxidized Ti6Al4V titanium alloy,both the wear track depth and wear rate decreased.Comprehensive analysis indicates that the optimal thermal oxidation parameters are 650 ℃ and 10 h.关键词
