In a threaded joint for pipes constituted by a pin and a box, each having a contact surface comprising a threaded portion and an unthreaded metal contact portion, the contact surface of the pin has a solid corrosion protective, preferably transparent coating based on a UV-curable resin and the contact surface of the box has a solid lubricating coating having plastic or viscoplastic rheological behavior which is preferably formed by the hot melt technique from a composition comprising a thermoplastic polymer, a wax, a metal soap, a corrosion inhibitor, a water-insoluble liquid resin, and a solid lubricant.

A method for performing a coiled-tubing process, the method having the steps: performing a coiled-tubing process using a fluid-lubricant composition that includes a sulfur-containing compound, and introducing the fluid-lubricant composition into a subterranean wellbore casing.

The invention relates to a polyamide-based sliding material, having fillers that improve the tribological properties, wherein the fillers comprise at least one metal sulfide and/or calcium phosphate. The invention further relates to a plain-bearing composite material, having a metal support layer, in particular made of steel or bronze, optionally a porous carrier layer, in particular made of bronze, and a sliding material, which fills the pores in the carrier layer, and to a three-dimensional shaped body for sliding load, consisting of a sliding material, in particular produced as an injection-molded or extrusion part and/or by additive manufacturing. The invention further relates to a plain-bearing element produced from a plain-bearing composite material comprising a shaped body

Lubricant composition, in particular a cooling lubricant solution, based on ionic and/or organoelemental compounds.

The disclosure provides for a valve including a surface movably engaged with another surface. A coating is on the surface and is characterized by: a CoF of less than 0.1; a hardness in excess of 1,200 HVN; impermeability to liquids at pressures ranging from 15 and 20,000 psi; a surface finish of 63 or less; and a thickness ranging from 0.5 to 20 mils. The disclosure provides for material constructions including a continuous phase, including a transition metal, and a discontinuous phase, including a solid dry lubricant. The disclosure also provides for a method of depositing a coating that includes depositing a first layer of a coating onto a surface using electroplating, electroless plating, thermal spraying, or cladding, and then depositing a second layer of the coating onto a surface of the first layer using sputtering, ion beam, plasma enhanced chemical vapor deposition, cathodic arc, or chemical vapor deposition.

The invention relates to a polyamide-based surface material having fillers which improve the tribologically active properties, wherein the fillers comprise at least one metal sulfide and/or calcium phosphate. The invention further relates to a three-dimensional molded body consisting of a surface material, produced, in particular, as an injection-molded part or extrusion part and or by additive fabrication.

An industrial lubricant composition including an oil base selected from the group consisting of vegetable oil, Group I, Group II, Group III, Group IV, Group V and combinations thereof and a phosphorus-based non-chlorine additive. The industrial lubricant also includes at least one intercalation compound of a metal chalcogenide, a carbon containing compound and a boron containing compound, wherein the intercalation compound may have a geometry that is a platelet shaped geometry, a spherical shaped geometry, a multi-layered fullerene-like geometry, a tubular-like geometry or a combination thereof.
