Abstract

In this work the results obtained from the study of ductility in a hard chromium coating electroplated onto the inner wall of a stainless steel ring are presented. This ring represents the cross section of a pipe to be joined by interference, so it will suffer thermal shock during assembly and will be subjected to high hoop stresses in normal operating conditions. In order to evaluate both the ductility and strength of electrodeposited chromium, different types of specimens from the original coated part were machined and tested in tensile and three and four points bending modes. Ductility and strength in the coating are evaluated through the relationship between the crack density in the coating,
