California Air Resources Board proposes aggressive deadlines for a transition from hexavalent chromium plating to trivalent chromium.

The meeting provides a brief background on hexavalent chromium, an overview of metal finishing regulations, the initial regulatory focus of PR 1426.1 and background on the rule development process.

This paper presents recent industry specific hard chromium technology advancements such as meeting the needs of the automotive and hydraulic industries.  Examples for additional improvement potential are shown to simplify the operation and make hard chromium plating even more reliable in its specific needs for a wide range of industries served.

This paper shows information learned from a NASF/AESF Foundation Research grant which has led to successful application. The work at the University of Houston (UH) is discussed – a technique developed to perform in-situ analysis of the stress of the chromium deposit from a REACH-compliant trivalent chromium electrolyte. An understanding of crack formation during plating has led the way to a means to avoid it. Faraday Technology Inc. scaled-up and optimized the same process through support from the U.S. Army. The results enabled significant chromium coating performance enhancements, matching the wear index of conventional Cr deposits from hexavalent baths.

The latest in the California regulatory battle over the phase-out of hexavalent chromium use in finishing operations.

MFASC meeting with the South Coast Air Quality Management District over proposed lower emission levels for hexavalent chromium.

Alert for Platers: Your Deadline is March 19, 2013 as EPA finalized the residual risk and technology review for the national emission standards for hazardous air pollutants (NESHAP) for hard and decorative chromium electroplating and chromium anodizing tanks under 40 CFR Part 63

The trivalent process is proven to be a safe replacement for hex chrome, but fundamental knowledge of its composition is required.

By improving tribological properties as well as corrosion resistance, hard chromium plating can lower energy consumption of moving parts and machinery, reduce the need to replace parts frequently, leading to reduced waste and improved efficiency.

Attorney and environmental expert Anthony Giuliani explains the EPA's new chromium rules due in 2012, which would amend the existing National Emission Standards for Hazardous Air Pollutants Emissions for hard and decorative chromium electroplating and chromium anodizing tanks by lowering the existing NESHAP limits for both existing and new sources.
