Abstract:
A lubricating composition and method are disclosed for lubricating the inner wall of a hollow conduit and the outer surface of an insulated flexible electrical conductor installed in the conduit. The lubricating composition is a powder comprised of the following powdered ingredients: lubricant such as talc; drying agent such as a micron-mesh silica; surfactant such as calcium stearate; odorant such as sassafras; and colorant such as a nontoxic food or cosmetic dye. The lubricating method first includes the step of blowing a quantity of a powdered lubricating composition into a hollow conduit resulting in the deposition of powdered lubricant on the inner wall of the conduit. In the next step of the method, an insulated flexible electrical conductor is inserted into the pre-lubricated conduit whereby powdered lubricant on the inner wall of the conduit rubs off onto the outer surface of the insulation of the electrical conductor thereby lubricating the insulation as it advances through the conduit.
Abstract:
The present invention relates to a lubricant for use in the drawing and ironing of black plate steel during the manufacture of enclosed containers such as cans. The lubricant comprises an aqueous solution of an active component, such as a major portion of molybdenum disulfide, together with minor amounts of waxes and other materials. In performing the method of the present invention, a lubricant system is employed. The lubricant system comprises a dual lubricant coating. The first, or outside, coating is applied to that portion of the black plate steel which ultimately becomes the outside surface of the can body. The outside coating is applied, such as by spraying or gravure or offset printing, at a rate of about 25 to about 200 milligrams per square foot of steel surface. This coating is dried, as through the use of a heat source, such as infrared heat or hot air. A second, or inside, coating is applied to that portion of the black plate steel which ultimately becomes the inside surface of the can body. The inside coating may also be applied to the surface of the black plate steel in a manner similar to that used for the application of the outside coating. After the can body is produced, the outside and inside lubricants must be totally removed. Such removal may be achieved by washing the can bodies in an alkaline solution (pH about 7.5 to 11.5) having a temperature of about 140.degree. to about 160.degree. F.
Abstract:
A tribological system, comprising a main body and a sandwich lubrication, in which the sandwich lubrication includes a binder-free solid lubricant layer comprising a solid lubricant, and a lubricant layer comprising a lubricant. The binder-free solid lubricant layer and the lubricant layer are present as separate layers on the main body and wherein the mass ratio of solid lubricant to lubricant is at most 0.05:1.
Abstract:
In some examples, an article includes a substrate and a coating on the substrate. The coating includes a stabilized microstructure including Magnéli oxide phase including an oxide of at least one of W, Mo, Nb, Ta, or Re. In some examples, a technique may include forming a coating including a refractory metal on a surface of a substrate. The technique also may include heat treating the coating at a temperature between about 500° C. and about 700° C. to form a coating including a stabilized microstructure including Magnéli oxide phase. The stabilized microstructure including Magnéli oxide phase may include an oxide of at least one of W, Mo, Nb, Ta, or Re. In some examples, the coating including the stabilized microstructure including Magnéli oxide phase exhibits a coefficient of friction that is at least 25% less than the coefficient of friction exhibited by the as-deposited coating under similar conditions.
