Morphology of the corrosion rust layers was observed by means metallographic microscope and SEM; the structure of them was detected using X-ray diffractometer and the distribution of the alloy elements in the layers were determined by EPMA. The corrosion of these steels in given environments is an electrochemical process, in which cementite plays a role as cathode and ferrite as anode. The rust layers formed on carbon steel are not clearly stratified. A large number of cracks and holes were found in the rust layers, which make the steel protect from corrosion uneffectively. However, the rust layers on the steel 36 CuPCr and that made in Japan are stratified. The interior layer which consists of Fe_3O_4 appears to be very homogeneous, adhesive and compact. In addition, Cu, P and Cr concentrated in the layer and localized on the side nearby matrix. All these improve the corrosion resistance of steels. 收稿日期: 1987-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 魏翔云 李有柯 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I3/246 1 北京钢铁学院金属腐蚀教研组.金属腐蚀原理(二),1979 2 杨文治.电化学基础,北京大学出版社,1982 3 岡田秀弥,细井祜三,汤川憲一,内藤浩光.鉄鋼,1969;55(5) ;355-365岡田秀弥.防食技术,1971;20(4) :178-191O No related articles found!
