摘　　要：采用俄歇电子能谱分析、电子探针X射线能谱分析、扫描电镜、金相显微镜和数学回归分析等方法研究了HSn70 1A黄铜的原始表面膜特征及其海水腐蚀行为。证实了原始表面膜对黄铜的初期海水腐蚀行为的影响 ,而长期的腐蚀行为则是由实海暴露过程中形成的腐蚀产物膜特征决定的。The characteristics of original surface film of brass HSn70-1A and its corrosion behavior in seawater were investigated by means of Auger electrical spectrum analysis and electric detective analysis of X ray spectrum,SEM,metallurgical microscope,mathematics regression analysis. It is shown that the original surface film has a influence on the corrosion behavior of brass during short period exposure in seawater, while that of long period is determined by the characteristics of corrosion film subsequently formed during the exposure.
