摘要
介绍了通过腐蚀试验来评价电气、电子产品、装置在使用及储备条件下的耐腐蚀性能,最新的多种低浓度混合气体试验方法的研究现状,ISO、IEC及日本标准JIS中的标准腐蚀性气体试验方法。讨论了模拟一般环境下SO2及H2S混合气体的试验条件,对铜试样做含臭氧的高加速混合腐蚀性气体的试验方法。探讨了交流阻抗法应用于腐蚀性气体试验及其影响因素。
To evaluate corrosion resistance and reliability of electronic device in operation and stor age condi tion,corro sive gas tests are performed.Recently many kind of mixed gas tests with low concen tra tion are investigated in some technical committees,and adopted in international standards,ISO,IEC,and Japanese industrial standards(JIS).SO 2 and H 2 S mixed gas test was suitable for simu lat-ing the ordinary envi ronment.The mixed gas test with ozone accelerates the corrosion of copper,while sim ulating the ordi nary environment.Impedance measurement results reflect the effect of cor -rosive gas.
