Abstract
Abstract This invention relates to an improvement in the plating of ductile semi-bright nickel from aqueous acidic nickel electroplating solutions, by the addition of three conjunctive ingredients, i.e., an aryl sulfon, an acetylenic alcohol and an olefinic alcohol. The conjunctive use of these three types of compounds produce excellent semi-bright nickel deposits which are ductile, finegrained and which exhibit improved leveling characteristics. Specific compounds which can be utilized are (1) metasulfobenzoic acid or its salts; (2) butynediol or hexyne diol; and (3) butene diol and butenol alcohols. Aldehydes, such as chloral hydrate and formaldehyde, may be added to assist in grain refinement and in reducing the sulfur content of the bath.
