The Electrochemical Behaviour of AISI 304 Stainless Steel Following Surface Modification by Ion Implantation

An austenitic stainless steel (AISI 304) has been surface implanted with nitrogen at room temperature. Ion implantation is an effective surface modification to improve the corrosion performance of metal materials. Using Electrochemical Impedance Spectroscopy (EIS), the electrochemical parameters which characterised the stability of passive films were calculated from the simple data of the response curves. The experimental results indicated that the stability of passive films and the pitting resistance of AISI 304 stainless steel are improved by nitrogen ion implantation.

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.
