In this study, comparative investigation of thermal oxidation treatment for Ti-6Al-4V was carried out to determine the optimum oxidation conditions for further evaluation of corrosion-wear performance. Characterization of modified surface layers was made by means of microscopic examinations, hardness measurements and X-ray diffraction analysis. Optimum oxidation condition was determined according to the results of accelerated corrosion tests made in 5m HCl solution The examined Ti-6Al-4V alloy exhibited excellent resistance to corrosion after oxidation at 600 degrees C for 60 h. This oxidation condition achieved 25 times higher wear resistance than the untreated alloy during reciprocating wear test conducted in a 0.9% NaCl solution.
在本研究中，对Ti-6Al-4V进行了热氧化处理的对比研究，以确定最佳氧化条件，以便进一步评估其腐蚀磨损性能。通过微观检查、硬度测量和X射线衍射分析对改性表面层进行了表征。根据在5m HCl溶液中进行的加速腐蚀试验结果确定了最佳氧化条件。所研究的Ti-6Al-4V合金在600℃氧化60小时后表现出优异的耐腐蚀性。在0.9% NaCl溶液中进行的往复磨损试验中，这种氧化条件下的耐磨性比未处理的合金高25倍。
