Energy conservation in chromium plating through use of non-conventional anodes

High rates of power consumption are an important problem in chromium plating because of the associated low cathode efficiency. Research aimed towards achieving an increased production rate via increased efficiency is in progress and several bath modifications are reported. Conventional anodes like lead or lead - tin alloy continue to be used for chromium plating inspite of their many disadvantages. The use of nonconventional noble metal coated anodes have been assessed experimentally. Results indicate wide scope for their usage in terms of reduced chemical and electrochemical attack, trivalent chromium build up and electrical energy consumption.
