Historical publication digitized from print 2017 [by Natural Resources Canada]. Includes bibliographical references. "Stable copper cyanide plating baths which can be operated at 25C (77F) have been developed. These conform to both of the following relationships: (1) OH- normality "free" CN- normality, and (2) total NaCN normality/Cu normality varies between 2.6 and 2.9, depending on the bath concentration. Advantages of these baths include: (1) comparatively simple control of bath compositions; (2) improvement in the nature and adhesion of the copper deposits, and in the plating cell operating conditions; (3) ability to use higher cathode current densities; (4) ability to copper plate high strength steel such as Type 4037 without embrittling the steel; and (5) ability to plate comparatively thick copper coatings directly on steel without the use of a "strike" bath"--Abstract, p.
