Morphology and Properties of Solid Chrome Plating, Obtained by the Galvano-Mechanical Method

Abstract:

In this article, studies of chromium coatings obtained by a conventional electroplating method, as well as by electroplating combined with mechanical processing, were carried out. The metallographic investigations and the micro-hardness tests of the coating were carried out and characteristic types of electroplating chromium coatings were determined. It was determined that the coating obtained by galvano-mechanical processing (current density – 75 A/dm², solution temperature – 58 °C, chrome plating time – 45 min) does not have dendritic defects, fits snugly to the base material, however, is characterized by an increased fragility. The micro-hardness of the galvanic chrome plating, obtained by electroplating, with a load of 100 g, is 960...990 HV. The surface of galvanic chromium coatings obtained under different conditions was investigated, the advantage of the galvano-mechanical technology of applying a chromium coating, implemented on the sample under study, was shown.
