  • Aircraft wheel part having improved corrosion resistance
    Patent number: 7475762
    Abstract: A steel member (10) having wear and corrosion resistance through a combination of coatings is disclosed, the steel member (10) being a hardened and tempered steel member having a high tensile strength, at least one selected portion (18) of the steel member (10) coated by thermal spraying with a tungsten carbide-cobalt composition (22) to provide wear and corrosion resistance, the tungsten carbide-cobalt composition (22) being approximately 78-90% tungsten carbide and approximately 10-19% cobalt, and a sacrificial ceramic-metallic coating (24) on the steel member (10) to provide corrosion resistance for the steel member (10). A method of coating a steel member (10) is also disclosed.

  • Method for restoring a surface on a metal substrate
    Patent number: 6524646
    Abstract: A method of restoring a damaged surface of a substrate to a functional condition through a filler material consisting essentially of tungsten disulfide and epoxy resin having a 10:1 ratio by weight. The filler material is cured after being applied to the damaged surface by uniformly raising the temperature to a cure temperature of the epoxy to allow any volatiles to evaporate without the creation of voids in the surface such that the resulting porosity prevents corrosion of the substrate when exposed to aromatic fuels at temperatures of 350 degrees F. The filler material consists of tungsten disulfide and a two part epoxy such as Hysol EA 9394/C-2.
