Abstract
Three kinds of complexing agents were selected to investigate their effects on the morphology and porosity of electroless nickel (EN) deposits on a mild steel substrate. The porosity of the EN coating was tested as a function of the variety of complexing agents with both an electrochemical technique and commonly used chemical spot tests. Meanwhile, the morphology and surface roughness of deposits were examined by atom force microscopy (AFM). It was found that the more stable is the nickel complex, the lower the roughness and the less the porosity of the coating. The reason for this is discussed, considering the complexing agent's effect on the deposition process of EN.
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.
