Abstract
This paper presents a review of early work with sulphamate electrolytes and reports certain new developments on nickel plating from sulphamate solutions. Experimental work is described which deals with the nickel suiphamate bath with and without addition agents. Particular emphasis is given to the physical properties of the deposits and the effect of bath composition and operating variables on stress, hardness, tensile strength, elongation and ductility. Photomicrographs showing the structure of the deposits and data on certain electrical properties are presented. The results of these studies indicate that the nickel deposits produced from the sulphamate bath are particularly applicable to engineering and functional uses. Several such applications are described.
