Abstract
Metal, carbon, or other original surfaces of articles, such as pneumatic and hydraulic cylinders, having scored or marred surfaces can be rehabilitated by applying to them a composition consisting essentially of a mixture of powdered molybdenum disulfide and epoxy resin, curing the resin, and removing excess material. The coating is as hard as steel, has lubricative action, and can withstand high temperatures.
Claims6
A repair process for restoring damaged metal, carbon, or other original surfaces by filling score marks, grooves, and other irregularities in the surface of articles such as pneumatic and hydraulic cylinders without changing the basic dimensions of such articles comprising:
- filling all scores, grooves, and surface irregularities of said surface with a mixture of finely powdered molybdenum disulfide and epoxy resin adhesive,
- wiping the filled surfaces to remove any excess mixture where it extends significantly above the original surface level, and
- curing said resin at a temperature well above ambient for a time sufficient to complete the cure thereof and provide a material hard as mild steel and resistant to hydraulic fluids,
- said mixture consisting essentially of from 10% to 90% by volume of said disulfide of particle size no larger than 60 microns and from 90% to 10% by volume of said resin adhesive, said adhesive being a glycidyl polyether of bisphenol-A containing a curing agent and having a Brookfield viscosity of 400,000 cps at 75.degree.F.
