Corrosion Resistance Mechanism of a Chromium-Free Zinc-Flake Coating Film on Scratched Areas -
Chromium-free zinc flake coatings (zinc-rich paint) are used for automotive parts and construction parts, etc. that require a high degree of corrosion protection. The demand for this process is extremely high due in part to its being an environmentally-friendly, chromium-free process. Currently, the automotive industry and others are looking for this type of coating which exhibits superior performance. In 2008, we studied the high corrosion resistance mechanism of the chromium-free zinc flake coating film using polarization curves. Currently, we are working on studying this mechanism in greater detail, focusing on how corrosion is controlled, even on areas that are scratched.

Functional Trivalent Chromium Electroplating
This paper will discuss recent research work on the development of a functional trivalent chromium plating process from a single, simple-to-control trivalent-based electrolyte to replace hexavalent chromium plating. 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.
