Abstract

A thick passive film showing interference colours has been obtained on 304 stainless steel in sulfuric acid solution without Cr 6+ ions by applying alternating square wave polarization. An investigation of the chemical composition and the distribution of valence states in the profile of the film has been carried out by using XPS. A mechanism for the colouring process is proposed.

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.
