ABSTRACT:
A composition suitable for the protection of corrodible metal surfaces which comprises a binder and a filler. The filler is constituted of a mixture of a comminuted refractory ferro alloy and a non-metallic inhibitor such as zinc chromate or zinc yellow, the latter being present in an amount sufficient to enhance the corrosion protection and weldability of the coated metal surfaces. Various binders, both inorganic and organic, may be used and the filler is preferably a mixture of a major amount of ferrophos (Fe.sub.2 P) and a minor amount, e.g., about 10 percent by weight of the filler, of zinc yellow.
