| 摘 要： | 为修复损伤的 Ti600合金结构件,开发新型耐蚀涂层,应用 Nd:YAG 激光在 Ti600表面制备了钛基梯度功能涂层材料(Functional Gradient Materials,FGM),并测试其耐腐蚀性能.结果表明,Ti600基体和 FGM 耐蚀性均较好;在微观上均呈现局部腐蚀的特性,表面呈腐蚀微坑形貌;极化电位较低;自腐蚀电流小,在30~90 nA/cm2之间.FGM 耐蚀性能较 Ti600得到提高,腐蚀电流为 Ti600的72% |

| Abstract: | A new type corrosion resistant coating was developed to fix damaged the Ti600 structure. The titanium-based functional gradient material （FGM） coating was prepared by applying Nd：YAG laser process, and corrosion resistance of which was test. The results showed both main body of the Ti600 structure and the FGM coating had relatively high corrosion resistance. At the micro level the structure showed partially corrosion micro-pits on surface, relatively low polarization potential, low corrosion current density （between）. Compared with Ti600, corrosion resistance of the FGM coating was improved. Corrosion current density the FGM coating was 72% of that of Ti600. |
