Abstract
A compound comprising molybdenum disulfide emulsified in a resin of the para phenyl phenol formaldehyde group, diluted in a vehicle of the methylbenzene group in a homogenized emulsion is deposited onto metal surfaces preheated to a surface temperature of 350.degree. to 500.degree. F. The heat stored in the metal promotes quick evaporation of the benzene vehicle while the resin sets. The cure and evaporation of the carrier may be further promoted by baking the coated article in an oven at a temperature of 300.degree. to 500.degree. F.
Claims2
A method of coating articles with a dry lubricating film comprising the steps of:
- heating the article until a surface temperature of 300.degree.-500.degree. F. is achieved thereon;
- depositing an emulsion of powdered molybdenum disulfide emulsified in a solution of methylbenzene and paraphenyl phenol formaldehyde;
- and
- heating the coated article in an oven at a temperature of 300.degree.-500.degree. F. until the solution sets up.
