Analysis between corrosion results and environment factors of the full-immersion and the tide zone of LY12CZ in Xiamen Coast

The method of grey relevancy was applied to analyzing the effect of the ocean and atmosphere factors on general corrosion and pitting of the alloys LY12CZ in full-immersion and tide zone in Xiamen respectively, and the affecting sequence of factors is obtained. According to the failure mechanism discussion, the calculate results can be accepted. This method can be used to analyze corrosion data in complicated environments.
