摘要: 用SSRT法研究了含锡0.1～2％的70/30黄铜在蒸馏水(0V,SCE)以及在Mattsson溶液(pH7.2,开路电位)中的SCC敏感性。结果表明,在蒸馏水中70/30黄铜抗SCC的最佳锡含量为0.4％;而在Mattsson溶液中,随含锡量的增加,抗SCC性能提高。加锡使黄铜的沿晶开裂向穿晶过渡。分析试验溶液表明,锡的主要作用是抑制了黄铜的脱锌。Mattsson溶液中原有的铜离子在SCC过程中还原沉积,不能用常规的脱锌系数评定黄铜的SCC。此时,单位面积锌的溶解速率却与裂纹平均扩展速率有合理的对应关系。

Abstract：The susceptibility of 70/30 brass with various Sn contents in the range from 0.1% to 2% to stress corrosion cracking (SCC) in distilled water (applied potential of OV, SCE) and Mattsson solution(pH7. 2,open circuit condition) subjected to slow strain-rate test(SSRT)was investigated. The results showed that 70/30 brass containing 0.4％ Sn exhibited optimum resistance to SCC in distilled water, while in Mattsson solution the resistance to SCC increased with the increases of Sn content. The addition of Sn was in favour of the transition to transgranular cracking from intergranular cracking in the brass. The analysis of the test solution indicated that the primary effect of Sn upon the inhibition of the SCC of 70/30 brass was due to its effect upon the surpression of dezincification. It was unable to evaluate the susceptibility of the brass to SCC in Mattsson solution by the conventional dezincification coefficient as the inherent copper ions in the solution were deposited by reduction during the SCC process. In this case,a reasonable agreement was found between its zinc dissolution rate per unit area and the average crack propagation rate.
