Herman AmayaMark Schario, Columbia Chemical's Chief Technology Officer, received the Award of Appreciation for his collaboration and accomplishments in developing B1026, the Standard Test Method for Measuring the Thickness of Chromium and Chromium Alloy Deposits by Coulometric/White Light Interferometry.
B1026 helps adapt chromium testing to the recent PFAS/PFOS regulation by measuring the thickness of chromium and chromium alloys.
According to Schario, this standard provides a new, valid method for measuring trivalent chrome. Schario notes that it comes as the industry moves away from decorative hexavalent chrome due to recent environmental regulations of PFAS/PFOS compounds in this plating type. Equipment manufacturers, tier suppliers, and electroplaters are increasingly leaning into trivalent chrome plating as an alternative.
“Existing test methods using coulometric and X-ray for thickness measurement are inaccurate when evaluating chromium deposits from trivalent chromium plating solutions due to its alloy properties,” says Schario. “This new standard has identified and uses a physical measurement, so alloying elements of the chromium deposit will not interfere when determining thickness.”
Currently, the committee is seeking test labs to help validate the standard for precision and bias.
Oscar GarciaOther honorees include:
- Herman Amaya, Manager of Metallurgy and Corrosion at Schlumberger Technologies, received the Award of Appreciation for his collaboration and accomplishments in developing B1025- Standard Specification for Electrodeposited Nanostructured Zinc-Nickel Coatings.
- Oscar Garcia, a Metallurgist at Sigma Fasteners, received the Award of Appreciation for his collaboration and accomplishments in developing and supporting B1025, the Standard Specification for Electrodeposited Nanostructured Zinc-Nickel Coatings.
Key benefits of the new Nanostructured Zinc-Nickel and the ASTM specification B1025-24:
- Improved corrosion protection
- Increased durability
- Enhanced performance
- Reduced Environmental impact
