CORROSION CHARACTERISTICS OF Cu IN TYPICAL INLAND SALTY SOILS
铜在典型内陆盐土中的腐蚀特点

By means of naturally burying specimens in two typical inland salty soils the corrosion behavior of pure Cu was examined.Then the corrosion characteristics of pure Cu and its corrosion products were analyzed by using SEM,EDAX and XRD.The results showed that Cu was pit-corroded in large area in Geermu salty soil and was partly deep spot-corroded in Kuerle desert soil which contained less salt.It was concluded that the corrosion of Cu mainly resulted from the amount of O2,Cl- ,SO2-4 and water content in soil as well as the soil texture.
