Abstract: A coating composition comprises a slurry consisting essentially of an aluminum neutralized phosphate bonding solution and aluminum powder. The bonding solution advantageously contains a relatively small but essential amount of vanadium pentoxide and, preferably, magnesium. A process for forming the bonding solution component of the coating slurry includes equilibrating an aqueous phosphate solution with a small but controlled and necessary amount of solute aluminum prior to adding aluminum powder to form the slurry. The present invention overcomes the problem of bonding solutions which require environmentally disadvantageous chromates or molybdates.

Abstract: A coating composition for ferrous metal alloy surfaces comprises a slurry consisting essentially of an aluminum neutralized phosphate bonding solution and aluminum powder. A process for forming the bonding solution component of the coating slurry includes equilibrating an aqueous phosphate solution with a small but controlled and necessary amount of solute aluminum prior to adding aluminum powder to form the slurry. The bonding solution preferably also contains magnesium. The present invention overcomes the problem of bonding solutions which require environmentally disadvantageous chromates or molybdates to neutralize the bonding solution prior to formation of the slurry.

Abstract: A seal coat composition comprises a slurry consisting essentially of an aluminum neutralized phosphate bonding solution and iron oxide (Fe.sub.2 O.sub.3) powder. The bonding solution advantageously contains a relatively small but essential amount of vanadium pentoxide and, preferably, magnesium. A process for forming the bonding solution component of the coating slurry includes equilibrating an aqueous phosphate solution with a small but controlled and necessary amount of solute aluminum prior to adding iron oxide powder to form the slurry. The present invention overcomes the problem of bonding solutions which require environmentally disadvantageous chromates or molybdates to neutralize the bonding solution prior to formation of the slurry.
