Influence of plating bath composition and steel surface treatment on corrosion resistance of cadmium coatings [electronic resource] / A.W. Lui and G.R. Hoey, Extraction Metallurgy Division. Ottawa : Information Canada, 1973. iv, 8 p. Technical bulletin ; TB 166 Cover title. "March 1973." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “The corrosion resistance of cadmium coatings on mild steel prepared from the Mines Branch cyanide plating bath and a commercial bath was assessed by means of humidified SO2-air and combined humidified SO2-air and environmental chamber tests. The mild-steel surfaces had been prepared by three different techniques. There was no significant difference in corrosion resistance between coatings on surfaces prepared by the same cleaning method but plated from different cyanide baths. However, the corrosion resistance of cadmium coatings on surfaces prepared by a nitric acid-acetic acid-phosphoric acid treatment was higher than those on surfaces prepared by other methods. The corrosion rates in the combined humidified SO2-air and environmental chamber test were higher than those in the humidified SO2-air test. The experimental results indicate that the service life of cadmium coatings of equal thickness is determined by the severity of the environment and the method of surface preparation but not by the type of cyanide plating bath used to plate mild steel"--Abstract, p. i.
