Method for restoring a surface on a metal substrate

摘要

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.
