Corrosion Behaviour of Amorphous Fe-Cr-Ni-C Alloys Synthesized by Magnetron Sputter Deposition

摘要: 以碳為阻晶元素,利用磁控濺射方法獲得非晶不銹鋼薄膜。用X-射線衍射、透射電鏡和動電位極化方法研究了碳含量與薄膜結構及耐蝕性的關系,并用AES和XPS分析了鈍化膜成分。結果表明;碳含量對薄膜的結構和耐蝕性有顯著影響;當碳含量超過6.2wt%時,薄膜轉變為非晶態結構。

Abstract: The results of a study of the effect of increasing carbon concentration on the crystalline-to-amorphous transition and corrosion resistance in high rate sputter-deposited 304ss-carbon alloys are reported. Charaterization using X-ray diffraction, transmission electron microscopy and auger electron microprobe analysis showed that the amorphous state was formed at carbon concentration greater than 6.2wt%.-
