Aluminum alloy coated pigments and corrosion-resistant coatings

摘要

This Invention relates to galvanic aluminum alloy powder-figments coated with a semi-conducting corrosion inhibiting oxide ad the process for preparing said coated powder-pigments in combination with film-forming binders for coating metal substrates to inhibit corrosion. The coated aluminium alloy powder-pigments are electrically active aid prevent corrosion of metals which are more catholic (electropositive) than the aluminium alloy pigments;
