The protection and compactness of the rust layer were evaluated by electrochemical analysis, absorption-desorption test, <em>etc</em>. The experimental results indicate that more compact rust layer could be derived from the rust particles with larger size. The well-established notion that the rust particle growth can induce the decrement of corrosion resistance of WS. However, the present investigation shows that the notion might not be universally accurate. The unusual result means that the rust particles might grow anisotropically during corrosion.","authors":[{"authorName":"Ming ZHANG","id":"2286c831-774e-44f1-95da-259348714067","originalAuthorName":"Ming ZHANG"}],"categoryName":"|","doi":"","fpage":"57","id":"cd27a56b-54fe-4852-b36e-0092c0b49772","issue":"1","journal":{"abbrevTitle":"JSXBYWB","coverImgSrc":"journal/img/cover/amse.jpg","id":"49","issnPpub":"1006-7191","publisherId":"JSXBYWB","title":"金属学报(英文版)"},"keywords":[{"id":"04c998e7-8517-40e4-b80a-c1f52fef301a","keyword":"Weathering steel","originalKeyword":"Weathering steel"},{"id":"623e18fc-bd77-436a-bd5e-520121c986b2","keyword":" corrosion","originalKeyword":" corrosion"},{"id":"59b9eca1-5145-4c2f-98a9-921b738b7cd0","keyword":" rust particle","originalKeyword":" rust particle"},{"id":"41c47ba0-7e30-4d10-85ac-a001cbd7ac0d","keyword":" <span style=\"color:red\">coarsening</span>","originalKeyword":" coarsening"}],"language":"en","publisherId":"1006-7191_2010_1_4","title":"Abnormal relationship between rust particles size and rust layer compactness of weathering steels","volume":"23","year":"2010"},{"abstractinfo":"Seven alloys containing different contents of rhenium and cobalt are investigated to explore systematically the effects of rhenium and cobalt on microstructures and gamma' <span style=\"color:red\">coarsening</span>.
