Trivalent chromium plating bath - contg. iron, cobalt nickel or manganese for improved quality at high current densities

摘要

A trivalent Cr plating bath contains 30-150 ppm of Fe, Co, Ni or Mn. The trivalent Cr is in the form of a water soluble complex from which Cr can be electrodeposited. The added metals prevent the formation of greyish deposits at high current densities.
