20100221574 | Zinc alloy mechanically deposited coatings and methods of making the same - A process for forming a zinc alloy coating on a metallic substrate is disclosed. The process includes the steps of (a) reacting a mixture including (i) a zinc powder and (ii) an oxide, a salt, or a combination thereof of an alloying metal more noble than zinc by heating the mixture at an elevated temperature for a time sufficient to form a zinc alloy powder including zinc and the alloying metal; and (b) mechanically depositing the zinc alloy powder on the metallic substrate, thereby forming the zinc alloy coating on the metallic substrate. The zinc alloy powder includes relatively high levels of the alloying metal, resulting in the ability to incorporate relatively high levels of the same into the zinc alloy coating during the mechanical deposition step. | 09-02-2010 |
20100266872 | PARTICULATE METAL ALLOY COATING FOR PROVIDING CORROSION PROTECTION - Coatings containing particulate metal alloy are disclosed. The coatings provide corrosion protection to a substrate, such as a metal substrate. The coatings contain zinc-metal-containing alloy in flake form, most particularly an alloy flake of zinc and aluminum. The coating can be from compositions that are water-based or solvent-based. The compositions for providing the coating may also contain a substituent such as a water-reducible organofunctional silane, or a hexavalent-chromium-providing substance, or a titanate polymer, or a silica substance constituent. the coating may desirably be topcoated. | 10-21-2010 |
