Abstract:The properties of solution chemistry for the process of trivalent chromium plating containing hy-pophosphite hace been investigated .The coofdination compounds between trivalent chromium ions and hypophos-phite ions have also been discussed. By means of potentiodynamic scanning and cyclic voltammetry,effects of elec-trochemical characteristics and hydrogen evolution on bath components have been studied.
Key words: trivalent chromium plating inert ligand hydrogen evolution
