Synergism Between Chemistry and Metallurgy for Invention

Abstract

This paper discusses the development of corrosion resistant and electrically conductive coatings based on physical property behavior learned from steel industry research. Commercial ferroalloys have been used to replace zinc and pure metal powders in these applications. In the first instance, an in-situ hydrolysis of the paint binder and subsequent reaction with ferroalloy alkali oxides produces an insoluble, adhefent barrier film. In the latter case, the platelet type structure of the ferroalloy powders maintains metal contact better than spherical pure metal powders when mixed with PVC binders.
