Influence of the structure of nodular cast iron on hard chromium plating quality

Popis výsledku v původním jazyce

This paper deals with the application of nodular cast iron as the substrate for hard chromium plating. There is a major impact of the structure and expecially graphite spherical nodules on the quality of the resultant chromium coating. The presence of spherical graphite on the substrate's surface causes that nodules on the surface of the chromium coating after electroplating. Two different samples of nodular cast iron were compared. The first sample was with nodeles after chromium plating and the secondone was without. In the metallographic cross section of cast iron coated with chormium with nodules there was found residual austenite in the martensite structure and ferrite around spherical nodules of graphite. This ferrite probably cause that the machining will not pull the graphite ball out of the surface of substrate. After that the graphite causes creation of nodules on the chromium coating.
