(John) Prevention of significant embrittlement in certain types of high-strength steels, prior to and during cadmium electroplating [electronic resource] / J. Bednar, W. Dingley & R.R. Rogers, Extraction Metallurgy Division. Ottawa : Queen's Printer, 1966. p. 497-501 : ill. Reprint series ; RS 14 Cover title. "Reprinted from Electrochemical Technology, September - October 1966." Historical publication digitized from print 2017 [by Natural Resources Canada]. Includes bibliographical references. "In the past, high-strength steels have become seriously embrittled during surface pretreatment and during subsequent cadmium electroplating. During this research, a method of chemical pretreatment was discovered by means of which the surfaces of Type 1062 and 4037 steels may be smoothed to eliminate sharp edges and cleaned for plating without introducing a significant amount of embrittlement. It also was found that specimens pretreated in this manner and plated with cadmium by a procedure previously developed by the authors are essentially free from embrittlement. Considerable success also has been obtained with Type 4340 steel. A chemical method of removing embrittlement and plating without introducing further embrittlement also was discovered. Evidence is presented to suggest that this type of embrittlement is primarily a surface phenomenon"--p. 497. gccst Steel gccst Processing Dingley, W. (Wilfred) Rogers, R. R.
