Abstract
Thin impermeable, corrosion-resistant, durable, dry lubricant coatings are provided as well as coated products and methods for the production thereof. The coatings comprise solutions of sulfur-containing metallic compounds and fluorocarbon polymers dissolved in mineral oil solvents and are applied to surfaces of substrates such as metallic surfaces.
Claims8
A coating composition for application to a substrate to provide an impermeable, corrosion-resistant, durable, dry lubricant coating of solid lubricants on the substrate, the coating composition consisting of a sulfur containing metallic compound, a fluorocarbon polymer and a mineral oil, the composition having a percentage weight of said sulfur containing compound of at least 7% and having a ratio by weight of said fluorocarbon polymer to said sulfur containing compound in a range of about 1:1 to 10:1.
A surface coating composition for application to a metal substrate to provide an impermeable, corrosion-resistant, durable, dry lubricant coating of solid lubricants on the substrate, the coating composition consisting of molybdenum disulfide, a fluorocarbon polymer, and a mineral oil, the composition having a percentage weight of said molybdenum disulfide of at least 7% and having a ratio by weight of said fluorocarbon polymer to said molybdenum disulfide in a range of about 1:1 to 10:1.
