A pin-box type threaded joint for steel tubes having a contact surface (30) including a threaded portion and a nonthreaded metal-to-metal contact portion has improved leak resistance, galling resistance, and corrosion resistance particularly to crevice corrosion. The contact surface of at least one of the pin and the box is coated with a first plating layer (34) made of a Cu-Zn alloy or a Cu-Zn-M1 alloy (wherein M1 is at least one element selected from Sn, Bi, and In). Optionally, an undercoat (32) of one or both of a Ni plating layer (32a) and a Cu plating layer (32b) and an overcoat of a Sn-M2 alloy plating layer (36) (wherein M2 is one or more elements selected from Bi, In, Ni, Zn, and Cu) may be formed below and above the first layer, respectively. A solid lubricating coating (38a) and a viscous liquid or semisolid lubricating coating (38b) may also be formed atop the plating layer as a lubricating coating (38).

摘要:
An antifriction coating comprises a lubricant, a corrosion inhibitor, and a solvent, wherein the lubricant comprises a mixture of phenolic resin, epoxy resin, polyvinylbutyral resin and polyolefin wax, and the corrosion inhibitor comprises aluminium particles, zinc particles and a metal phosphate. Substrates are preferably pretreated by a phosphating process prior to coating with the antifriction coating. The antifriction coating is useful for coating substrates such as nuts, bolts and other fasteners, door, bonnet and boot lock parts, hinges, door stoppers, window guides, seat belt components, brake rotors and drums, and other transportation industry related parts. The antifriction coating may be used alone or in combination with other antifriction coating.

摘要:
The invention relates to a lubricant which can be used as a mandrel lubricant with a content of 75 to 90 wt. % of graphite and contains 1 to 10 wt. % of a phosphate. Said lubricant can also contain 1 to 4 wt % alkali silicate, 1 to 10 wt. % bentonite, 0.5 to 1 wt. % silico-phosphate and common solid lubricants. Said lubricant is preferably used as an aqueous suspension with a solid content of 20 to 40 wt. %.
摘要:
Thin impermeable, surface hardened, corrosion-resistant, durable, dry lubricant surface finishes are provided as well as surface finished products and methods for the production thereof. The surface finishes comprise particulate mixtures of sulfur containing metallic compounds and fluorocarbon polymers and are applied to surfaces of substrates such as metallic surfaces.
摘要:
A carrier-free pulverulent metalworking lubricant composition. In one form, the composition contains from 2 to 30% by weight sulfur and at least one component having adhesive properties at forging temperatures, the composition being formed by a method comprising the steps of: (a) forming a dry mixture of said particulate lubricant components, and (b) agglomerating said admixture to form agglomerated particles. The application of the composition as a metal working lubricant significantly reduces smoke and oily waste generation in hot forging operations by eliminating the use of oils or volatile organic compounds as carriers, while providing acceptable performance, cleanability and sprayability.
摘要:
A composition for coating steel wire to facilitate the cold drawing thereof, said composition comprising: (A) from about 50 to about 99.99 % by weight of a component selected from the group consisting of Na2SO4, K2SO4, and mixtures thereof; (B) from about 0 to about 49.99 % by weight of a component selected from the group consisting of Na2B4O7, NaBO2, K2B4O7, KBO2 and mixtures of any two or more thereof; and (C) from about 0.01 to about 5 % by weight of a component selected from the group consisting of potassium soaps, sodium soaps, and ammonium soaps; wherein the percentages by weight are based on the total weight of components A, B, and C in the composition, and wherein not more than 50 % by weight of the total of sodium plus potassium plus ammonium ions in components A, B, and C of the composition consists of sodium ions.
摘要:
The composition of the present invention is a carrier-free pulverulent forging lubricant having at least one component having adhesive properties at forging temperatures and the method of the invention is a method of forging a workpiece in a die which includes the step of spraying onto at least one of the die and the workpiece a coating of an effective amount of a carrier-free pulverulent lubricant composition at ambient pressure. The use of the composition and method of the invention significantly reduces smoke generation in hot forging operations by eliminating the use of oils or volatile organic compounds as carriers.
