Abstract
SynopsisA method of obtaining adherent electrodeposits to electrodeposited chromium and high chromium alloys consists in cathodic polarisation for 5 minutes at 150 amps. per sq. ft. and 35°C. in a solution, nickel sulphate 240 g. per litre, sulphuric acid 50 g. per litre followed by nickel deposition and heat treatment, or preferably, by copper deposition.Chromium alloys, e.g., stainless steel, can be soft-soldered with ordinary fluxes after treatment for 5 minutes in the acid nickel sulphate solution.The method has been used to study quantitatively and qualitatively the adhesion of chromium deposits to various metals. Good adhesion of chromium to polished steel and nickel was obtained both without special preparation and also using preparatory methods of cleaning found suitable for other deposits. Preparation of steel by anodic treatment in the chromium plating solution was also found satisfactory.
