    摘要： A fastener such as a rivet, bolt or screw is provided with a protective coating for protection against corrosion and deterioration, formed by application of a mixture of a powdered metallic substance such as powdered aluminum or molybdenum disulfide with a phenol-formaldehyde resin in a volatile carrier from the group consisting of lower alkyl alcohols, methyl ethyl ketone and petroleum distillate, such as toluene or ethyl alcohol, or both, together with strontium chromate and zinc chromate. Either teflon or fatty amido diamine is added to the foregoing mixture. The thickness of the coating after drying can be made very thin and controlled to a high degree and possesses sufficient toughness and lubricity so that it is not damaged even when used on interference type fasteners.
