| 摘 要： | 依据航空标准评价了ＴＡ７钛合金和１Ｃｒ１１Ｎｉ２Ｗ２ＭｏＶ及Ｃｒ１７Ｎｉ２耐热不锈钢在３．５％ＮａＣｌ水溶液中的电偶腐蚀敏感性，研究了试样表面状态对电偶腐蚀行为的影响，探讨了腐蚀机理。结果发现，有关文献中材料的常规接触腐蚀数据不适合于压气机工况下的材料接触相容性设计，航标中的平均电偶电流密度指标不适合作为评价钝性材料接触腐蚀敏感性的判据。 |
| 关 键 词： | 钛合金 耐热不锈钢 电偶腐蚀 压气机 |

| Abstract: | The galvanic corrosion susceptibility (GCS) of heat resistant stainless steels 1Cr11Ni2W2MoV and Cr17Ni2 contacted with titanium alloy TA7 in 3 5% NaCl solution was evaluated according to aeronautic criterion The influence of surface conditions on GCS behavior and the GCS mechanism were investigated It is found that the GCS datum reported in literature is not useful for guiding the compatibility design of heat resistant stainless steels and titanium alloy used in compressor The galvanic current density parameter adopted in aeronautic criterion can not be used to evaluate GCS of passivation materials |
| Keywords: | titanium alloy heat resistant stainless steel galvanic corrosion compressor |
