摘要:
为提高Ti-6Al-4V钛合金表面的消光和耐腐蚀性能，研究了以铬酸盐复合钛为促进剂的黑色氧化膜制备工艺。用扫描电镜、X射线衍射仪等分析了膜层的形貌、结构、组成。用显微硬度计、TPE盐雾试验箱等检测了膜层的硬度、耐蚀性能。结果表明，获得的由锐钛矿型TiO2和部分金红石型TiO2组成的厚为5.0～9.0 μm的黑色氧化膜膜层是均匀、稳定，多孔性的。与基体相比，显微硬度和耐腐蚀性能有显著提高，耐腐蚀性能达到七级，满足了武器装备中钛合金部件表面改性处理的要求。

Abstract:
In order to improve the corrosion resistance and extinction performance of Ti–6Al–4V Titanium Alloy，the surface modification technique was used，and the process of making black oxidation film on the surface of Ti–6Al–4V Titanium Alloy was studied. The morphology,structure,and composition of the oxidation film were analyzed by means of scanning electron microscopy and X–ray diffraction. The hardness and corrosion–resistance of the film were evaluated. It was found that the oxidation film on the surface of Ti–6Al–4V Titanium Alloy substrate was uniform，stable，and porous. The results showed that the black oxidation film was 5.0～9.0 μm thick and was composed of anatase TiO2 as the major phase and a small amount of rutile TiO2. Compared with Ti–6Al–4V Titanium Alloy substrate, the micro–hardness and corrosion–resistance has a remarkable increase，with corrosion resistant up to the seventh and can meet the demands of surface modification of the Ti–6Al–4V Titanium Alloy for weapons and equipment.
