| Abstract: | The properties of solution chemistry for the process of trivalent chromium plating containing hypophosphite have been investigated. The coordination compounds between trivalent chromium ions and hypophosphite ions have also been discussed. By means of potentiodynamic scanning and cyclic voltammetry,effects of electrochemical characteristics and hydrogen evolution on bath components have been studied. |
