Abstract

This paper deals with the corrosion characteristics of the double-layer consisting of the epsilon phase and the complex oxide. The tests show that the double-layer protects the steel substrate effectively. The double-layer is superior in corrosion resistance to the single e-phase layer by three to four times, and to the e-phase / magnetite (Fe 3 O 4 ) layer by two times. The corrosion mechanisms have been investigated and discussed by means of metallography.

epsilon相/复合氧化物双层在低碳钢上的腐蚀行为

本文研究了由epsilon相和复合氧化物组成的双层结构的腐蚀特性。试验表明，该双层涂层对钢基体有较好的保护作用。双相层的耐蚀性比单e相层高3 ~ 4倍，比e相/磁铁矿(fe3o4)层高2倍。用金相方法对其腐蚀机理进行了研究和探讨。

期刊介绍： Transactions of the Institute of Metal Finishing provides international peer-reviewed coverage of all aspects of surface finishing and surface engineering, from fundamental research to in-service applications. The coverage is principally concerned with the application of surface engineering and coating technologies to enhance the properties of engineering components and assemblies. These techniques include electroplating and electroless plating and their pre- and post-treatments, thus embracing all cleaning pickling and chemical conversion processes, and also complementary processes such as anodising. Increasingly, other processes are becoming important particularly regarding surface profile, texture, opacity, contact integrity, etc.
