| 目的 研究AHБ，CuAl/NiC和NiCrAl/NiC三种可磨耗涂层的抗腐蚀性能。方法 对三种涂层试样进行盐雾试验、湿热试验和浸泡试验，并结合电化学测试分析不同涂层试样的抗腐蚀性能。结果 545 h的盐雾试验后，AHБ涂层的表面出现了一处微裂纹，CuAl/NiC涂层表明出现了涂层剥落现象，NiCrAl/NiC涂层的表面状况相对最好；三种涂层试样经过10个循环的湿热试验后均未见明显的腐蚀现象；经过15 d的浸泡试验后，NiCrAl/NiC涂层的表面状况相对较好，而AHБ涂层和CuAl/NiC涂层的表面状况相对较差；电化学测试结果也表明NiCrAl/NiC涂层的防护性能相对最好。结论 NiCrAl/NiC涂层的抗腐蚀性能相对较高，而AHБ涂层和CuAl/NiC涂层的抗腐蚀性能相对较低。 |

| Objective To research the corrosion resistance of three kinds of abradable seal coatings, including AHБ, CuAl/NiC and NiCrAl/NiC. Methods The corrosion resistance of the three kinds of coatings was analyzed by salt spray test, thermal-humidity test and immersion test, in combination with electrochemical testing. Results After salt spray test of 545 hours, NiCrAl/NiC coating revealed a relatively better property compared to that of AHБ and CuAl/NiC since a macro crack was found on AHБ coating and coating pill-off happened on CuAl/NiC; no obvious change was found during 10 days’ thermal-humidity test; while after 15 days’ immersion test, NiCrAl/NiC coating still showed a more stable situation than the other two coatings; the electrochemical results also provided a reliable evidence that NiCrAl/NiC had the best corrosion resistance among those three kinds. Conclusion The NiCrAl/NiC coating has relatively better corrosion resistance compared to that of AHБ and CuAl/NiC coatings. |
