Papers are invited for ASTM International’s Workshop on Workshop on Perfluoroalkyl and Polyfluoroalkyl (PFAS), percentages of Hexavalent Chrome in (Trivalent Chrome), and Cadmium Plating Properties, to be held May 7, 2025, in Toronto, Canada. The event is sponsored by ASTM International’s metallic and inorganic coatings committee (B08) and will be held in conjunction with the committee’s standards development meetings.

Changes made to the testing formula did not consider the susceptibility and environment stresses encountered in oil exploration caused hydrogen embrittlement failures (IHE). The objective of this workshop is to identify the stresses that were once accounted for in the original formula and make sure those same stresses are also accounted for in the new formula.

Topics for this workshop are:

• PFAs substitutes, direct testing and their properties,

• Trivalent chrome and identifying alternative options,
• Cadmium replacement, properties that prevent its replacement and areas we could look at for replacement of cadmium and nickel-cadmium plating,

Regarding test stresses, it will cover:

• Galvanic indifference, OCP of the substitute,
• Mechanical hardness- reduction of mechanical stress,
• Adhesion and ability to wear,
• Compressive properties- holds surface in compression to disallow salts from forming in substrate,
• Chemical stress, what chemical properties are present and how they protect,
• Tension, shear of the substrate, elongation, etc., and
• Co-efficiency of friction change.

Those interested in presenting at this workshop should submit a 250 to 300-word abstract pertaining to the above topics to workshop co-chairs no later than Mar. 31, 2025.

The workshop cochairs can be reached by email: John Carpenter (jcarpenter@uschrome.com), and Richard (Ian) MacMoy (ian@intermetallicgroup.com).
