Hexavalent chromium plating has been used for many years to provide hard, durable coatings with excellent wear and corrosion resistance properties. However, hexavalent chromium baths have come under increasing scrutiny due to the toxic nature of the bath, effects on the environment and worker health. In this work, we are updating accomplishments to achieve properties comparable to existing hexavalent chromium plating for functional applications. Work on achieving desirable thickness, uniformity, adhesion, porosity and corrosion resistance, as well as other material properties, will be discussed.
A research study was conducted on eight finishes that are potential replacements for cadmium. Information from the tests is specific to clamp load and corrosion, both cosmetic and galvanic...
