Cr(III) Conversion Layers on Zinc and Zinc Alloys: Evolution and Perspectives
Trivalent chromium conversion layers have successfully replaced hexavalent conversion chromium on zinc and zinc alloys for many applications, especially in the automotive industry since the entry in force of the ELV directive.

Non-PFOS, Permanent Mist Suppressants for Hard Chromium Plating, Decorative Chromium Plating and Chromic Etch Applications
Mist suppressants are an important tool for reducing exposure of workers to Cr(VI) during plating and etching operations. A common raw material used for efficient mist suppressants was, and still is, PFOS. PFOS is subject to legislation across the world prohibiting its use for many applications. In this paper we will present developments and experiences with non-PFOS, permanent and non-permanent mist suppressants.

Wood’s Nickel Strike
When I look in the literature or talk with other platers, I am told that Wood’s nickel is an easy bath to use and shouldn’t cause any problems. Generally, that seems to be the case, but is there any place I can get additional information about the strike bath?

If the final plated part does not meet specifications, the parts are stripped and sent through the electroplating process again. One of our engineers suggested that this can cause problems with hydrogen embrittlement.
