The California Air Resources Board (CARB) proposes agressive deadlines for transitioning to trivalent chromium.

The California Air Resources Board (CARB) appears to be set on a rule phasing out hexavalent chromium plating and anodizing processes that could disrupt industry and critical supply chains.

Help reduce environmental emissions, exposure and contamination without sacrificing plating efficiency.

This article is based on a presentation given at NASF SUR/FIN 2022, in Rosemont, Illinois, in Session 6, Responses to PFAS / PFOA.  It follows the case study of three facilities’ conversion from PFAS-containing wetting agents to non-PFAS equivalents, eliminating PFAS and moving forward with a smaller and more sustainable environmental footprint.  The journey of conversion from PFAS-containing wetting agents in both chromic-sulfuric etch and hexavalent decorative plating tanks can be complicated and winding due to deep rooted standard industry practices, as well as state and federal regulations.  Outlined here is a clear course of action that led to eliminating PFAS from the facilities’ wetting agent strategies. 

This study investigated the addition of Cirrus Alumina Dopant™, a nanoparticle additive, to a variety of low phosphorus electroless nickel baths to evaluate the performance of the resulting nanocomposite coating as a potential replacement for hard chromium.  The results offer a versatile substitute for hard chromium in a broad range of applications.
