A method to protect and modify surface properties of articles is disclosed. In one embodiment of the method, an intermediate layer is first deposited onto a substrate of the article. The intermediate layer has a thickness of at least 2 mils containing a plurality of pores with a total pore volume of 5 to 50% within a depth of at least 2 mils. A lubricant material is deposited onto the intermediate layer, wherein the lubricant material infiltrates at least a portion of the pores and forms a surface layer. The surface layer can be tailored with the selection of the appropriate material for the intermediate layer and the lubricant material, for the surface layer to have the desired surface tension depending on the application.

Methods and systems for providing cleaning and providing barrier coatings to interior wall surfaces of small diameter metal and composite piping systems in buildings. An entire piping system can be cleaned in one single pass by dry particulates forced by air throughout the building piping system by an external generator, and the entire piping system can be coated in one single pass by a machine connected exterior to the piping system. Small pipes can be protected by the effects of water corrosion, erosion and electrolysis, extending the life of piping systems such as copper, steel, lead, brass, cast iron piping and composite materials. Coatings can be applied to pipes having diameters of approximately up to approximately 6 so that entire piping systems such as potable water lines, natural gas lines, HVAC piping systems, drain lines, and fire sprinkler systems in single-family homes to apartments to high-rise hotel/resort facilities and office towers, apartment and condominium buildings and schools, can be cleaned and coated to pipes within existing walls. The coating forms an approximately 4 mils or greater covering inside of pipes. Buildings can return to service within approximately 24 to approximately 96 hours.

An inner surface-modified tube includes fine particles that are buried in an inner surface of a tube with part of surfaces of the fine particles exposed, wherein the fine particles are unevenly distributed such that more fine particles are distributed in a region from a center of the tube to the inner surface of the tube than in a region from the center of the tube to an outer surface of the tube based on a thickness direction of the tube, an arithmetic average roughness Ra of the inner surface of the tube is 1 nm or more and 100 m or less, a particle diameter of each fine particle is 10 nm or more and 100 m or less, and an inner diameter of the tube is 0.01 mm or more and 100 mm or less.

A heat releasing pipe includes a metal pipe and a surface coating layer. The metal pipe has an outer circumferential surface. The surface coating layer is provided on the outer circumferential surface of the metal pipe. The surface coating layer contains an inorganic glass base material and has concave portions and convex portions on an outer surface of the surface coating layer. The concave portions and the convex portions are constructed using electrocoating with an electrocoating resin. The concave portions have a virtually circular shape when seen in a direction perpendicular to the outer circumferential surface of the metal pipe and are lower than a first reference surface. The first reference surface has an average height of the outer surface of the surface coating layer. The convex portions are located on peripheral edge portions of the concave portions and surround the concave portions.

Disclosed is a method for reducing friction in a radial drilling application. The method involves coating the interior of a deflector shoe with a lubricant. Lubrication of the deflector show can be accomplished by applying a wet lubricant to the interior of the deflector shoe or spraying a dry lubricant on the interior of the deflector shoe. The method can further include coating a hose and/or a jet nozzle, passing the hose and/or jet nozzle through the coated interior of the deflector shoe. The method can further include coating components of a milling cutter, and passing the components of the milling cutter through the coated interior of the deflector shoe. An apparatus for reducing friction in a radial drilling application is also disclosed.

A tool for a catalyst coating apparatus to a honeycomb substrate of an exhaust gas-purifying catalyst is inserted into an outer cylinder having an axial length longer than an axial length of the honeycomb substrate supported by the outer cylinder in a state where an axial direction of the honeycomb substrate is arranged in a vertical direction. The tool comprises a cylindrical partition member having flexibility. An outer peripheral surface of the partition member faces an inner peripheral surface of an outer cylinder extension portion of the outer cylinder protruding upward with respect to an upper end surface of the honeycomb substrate. When the catalyst slurry is supplied to the upper end surface of the honeycomb substrate and an inside of an inner peripheral surface of the partition member, a lower end of the partition member is disposed in a vicinity of an upper end surface of the honeycomb substrate.

A spray rig for lining an interior surface of a pipe with a material. The spray rig includes a base, a motor, and a spray head. The spray head includes a mating component, a mixing chamber, a feed tube, an agitator, and a spray deflector. The mating component removably couples the spray head to the motor. The mixing chamber extends from the mating component and includes a plurality of slots. The feed tube extends from the mixing chamber and is configured to deliver the material to the mixing chamber. The motor is operable to rotate the agitator about an agitator axis to mix the material and to direct the material through the plurality of slots. The spray deflector is coupled to the agitator for rotation with the agitator and is configured to redirect the material from the mixing chamber and onto the interior surface of the pipe.
