ABSTRACT:
A process and electroplating bath for use in electrodepositing nickel on a base where the electroplating bath includes a coumarin compound and an aryl hydroxy carboxylic acid compound, such as salicylic acid, present in a combined amount effective to provide a ductile, self-leveling nickel deposit. The bath may further include hexyne diol and/or a material selected from the group consisting of primary acetylenic alcohols and adducts of primary acetylenic alcohols, as well as mixtures thereof. It has been found that excellent leveling and physical properties can be maintained utilizing such a bath, while at the same time, the usual coumarin concentration level can be reduced significantly and process life can be dramatically extended. In addition, additives such as butyne diol, and/or aldehydes such as formaldehyde and chloral hydrate may be utilized. It has also been found that corrosion resistance is substantially improved utilizing the process and electroplating bath of the present invention.
