  • Patent number: 7651556
    Abstract: A protective coating is formed on a metallic material surface by applying a treating agent comprising water, an alkali silicate, and, optionally, a lubricating component to the surface and drying the treating agent. The coating film thereby formed has excellent anti-galling and rust preventive properties. If a lubricating component is present, the coating film also has excellent self-lubricating properties.

  • Patent number: 7625439
    Abstract: The ferrous metal chemical conversion coating is comprised of mixed oxides and organometallic compounds of aluminum and iron. A ferrous metal substrate is immersed for a period of time in a bath composition, at a temperature, at a pH, and at a concentration for each constituent of the bath composition, that will form a coating with the desired characteristics. The bath composition comprises water, aluminum salt, oxalic acid, and an oxidizer. The conversion coating is amorphous in nature and can be formed as thin as 1 micron with a coating weight in the range of about 40-250 milligrams per square foot. When sealed with an appropriate rust preventive material, the coating enhances corrosion resistance of the ferrous metal substrate. It is an effective absorbent base for paint finishes. When top coated with a lubricant, the conversion coating aids (a) assembly of parts, (b) break-in of sliding surfaces, and (c) anti-galling.
