the patent application of the company M * Φ. Chemicals Ine. New York, USA

regarding electroplating processes

The priority of the July 7, 1963 application in the United States of America is claimed

The invention relates to a new method for electroplating, particularly to a method for producing shiny nickel deposits at high speed.

As is known to those skilled in the art, shiny niokel deposits can be used can be obtained by laying down different types of baths, e.g. from Watts-Niokel baths or from modified ones Watts nickel baths or from. Niokel peeling baths with high chloride content. Working with these previous baths

usually occurs by separating a precipitate on the nickel-containing solution with a current density between 1 and 10 amperes / dm ² (hereinafter abbreviated as aqd). In general, these baths contain various shine additives, usually a combination of two or more additives, which are necessary to obtain shiny, smooth deposits.

The time it takes for a rainfall of the usual strength of 0.003 to 0.05 mn is required depends on the current density and other procedural conditions.

Generally it takes time under the previous spot deposition conditions the deposition of a precipitate 0.025 mm thick . at the current densities of 8 to 2 normally used, for example at least 15 minutes and possibly up to an hour. In the Hegel, nickel plating processes are used, with less or moderate movement, i.e. slow relative speed executed between the bard and the cathode. This can be done, for example, by using a slowly moving cathode rail, by blowing air or a combination of these two methods. Such movement is below the usual used current densities to supplement the nickel content in the cathode film.

Although ββ is possible »content-sharing, glossy Kiokelniedersohläge by using such previous systems to achieve EU »it was found that the production speeds are undesirably low because of the time required; E.g. it takes 30 minutes to achieve a Precipitation of 0.025 mm. In addition, because of this slow deposition rate, it is necessary »relatively large. Containers to use which are unduly a lot of costly work claim.

Up to now, attempts have been made under various conditions to produce shiny, flat niocel tips at high speed. For example, attempts have been made to successfully use auxiliary systems operating under high strokes at normal Hiedersohlagsgeo speeds. The attempts were unsuccessful, however, because the previous gloss systems did not allow the production of glossy and correspondingly smooth deposits at high speed over a larger current range. These previous attempts to obtain such precipitates consisted, for example, in the use of various additives that act together, such as primary glazes, secondary glazes or auxiliary glazes.

If phenylpropiolamide is used together with a secondary shimmer, such as ZoBo saccharin, the precipitate has an unexpectedly high ductility.This high ductility is particularly achievable when the precipitate is deposited from chloride-free systems. The high ductility can be obtained over a reasonably wide concentration range of phenylpropiolamide. Earlier combinations of brighteners allow the production of a ductile deposit only under relatively narrow and difficult-to-control concentration limits of the primary brightener ₀
