Abstract:
Disclosed herein are a solid lubricating composition comprising a solid lubricant, a lubricating oil which is in a liquid or paste form at an ordinary temperature, a carrier for absorbing and possessing said lubricating oil, and a thermosetting synthetic resin binder, and a sliding member comprising a metal substrate and a solid lubricant composed of the lubricating composition.
Abstract:
A coating and bonding composition is disclosed. The composition includes suspending, bonding and thinning agents, and a metallic flake. The composition may be used with an environmentally friendly lubricating composition to form an environmentally friendly lubricating system for protecting threaded connections from galling or other damage. That system may be used in a method for protecting threaded connections that includes the steps of: coating me threads, prior to make-up, with the coating and bonding composition and then coating them with the environmentally friendly lubricating composition, after the coated threads have dried.

C. of from 10 to 1,000,000 cSt;(B) from 10 to 200 parts by weight of a filler comprising at least one member selected from the group consisting of calcium carbonate, zinc carbonate, a composite zinc white, and silica; and(C) from 0.001 to 0.1 part by weight of platinum or a platinum compound.
Abstract:
A synthetic resin composition having particles of metallic gallium or gallium alloy dispersed uniformly in a synthetic resin is particularly useful for the production of a surfacing material for a glider for use on snow or ice. When a molten paraffin wax is applied to such surfacing material, part of the wax penetrates into the resultant sheet to form a gallium-paraffin mixture on the surface of the gallium particles and at lower snow or ice temperatures, the gallium particles expand, and as a result of their expansion, the gallium particles are held strongly enough on the gliding surface of, for example, a ski to maintain good water-repelling and glide characteristic over a prolonged period without the gallium-paraffin mixture becoming detached from the ski. The composition is also useful for many other similar uses such as a plastic gear, a constructional material, a marine structural material and the like, because of its excellent glide, water-repelling and wear resisting properties, which can be retained for a prolonged period.
Abstract:
The present invention is, in one form, an aqueous alkaline metalworking fluid composition in the form of a concentrate which includes a salt of orthophosphoric acid; a dibasicdioic acid in an amount of up to about 5.0% by weight of the concentrate; an essentially phosphonate-free chelating agent; and, a neutralizing base. The composition may also include a lubricating agent, a coupling agent, a passavating agent, a biocide, and a colorant.
Abstract:
A friction material member particularly useful in high load and temperature applications and a method for making the same are disclosed. The friction material member is made by preparing a mixture of sinterable metal particles, carbonaceous material, friction enhancers and curable polymeric resin; the mixture comprising at least about 50 percent by weight of metal particles and sufficient resin to coat and bond the metal particles, carbonaceous material and friction enhancers. The mixture is molded and the resin cured to form a piece in a solid preformed shape corresponding to the shape of the mold. Thereafter, the preformed piece is heated in a substantially oxygen free atmosphere for a time and at temperatures and pressures sufficient to fuse at least a portion of the metal particles into a sintered metal matrix. The preformed piece may be sintered to a metal backing plate during the heating step, or may be welded, brazed or soldered to the plate after heating. The resulting product may be classified as a hybrid friction material, i.e., being a cross between semi-metallic and sintered full metallic friction materials.
Abstract:
The composite self-lubricating material according to the present invention comprises a metal matrix containing functional additives; the matrix is formed by two components, one forming shells of the functional additives, the other being located in the spaces between the shells.
Abstract:
Disclosed is a family of lubricants which are paste mixtures of powdered metals and oils or greases. These lubricants can be applied to gears, bearings, etc. by simple brushing on spraying on due to their pasty texture. And their adherence and longevity provide adequate lubrication with periodic applications as infrequently as once per week. Further, these lubricants possess good high temperature, high pressure, and corrosion resistance characteristics.
Abstract:
Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto and which melts within the range of about 30.degree.-100.degree. C. The composition comprises at least one neutral ester, and preferably a mixture of esters, prepared from polyalkylene glycols and saturated aliphatic alcohols having at least about 10 carbon atoms, and C.sub.12-25 aliphatic monocarboxylic acids and C.sub.4-20 aliphatic polycarboxylic acids. The preferred ester mixtures are prepared from polyethylene glycols, C.sub.14-20 predominantly straight chain alkanols, stearic acid and adipic, azelaic or sebacic acid. Optional ingredients include phosphorus acid salts and antioxidants. The composition may be applied in liquid form and solidifies on cooling to normal ambient and storage temperatures.
Abstract:
A method for producing high density metal-containing lubricants and for comminuting metal into fine spherical particles is provided by heating a carrier fluid such as a lubricant, for example, and a metal until the metal becomes liquid, admixing the two components to form a homogeneous dispersion of metal globules in the carrier fluid, and then cooling the mixture. When a lubricant carrier fluid is used, the resulting high-density lubricant contains discrete, spherical metallic particles dispersed therein and higher density is achieved without any consequent loss of lubricating properties.
