Anti-fretting wear coating for substrates

Номер: US20130130014A1

Автор: Hamidreza Mohseni, Jaimie S. Tiley, Thomas W. Scharf

Принадлежит: University of North Texas

A method and chemical composition and material structure for improving fretting wear in substrates, particularly carbon-carbon composite (CCC). The invention relates to trilayer coatings, comprising a base of hard ZrO 2 , a middle layer of Al 2 O 3 , and atop layer of lubricious ZnO. The coatings of the present invention exhibit conformality and pore-filling down to approximately 100 microns into a carbon-carbon composite to which they are applied. The methods for preparing the coatings include a chemical vapor infiltration route, such as an atomic layer deposition (ALD) process, to uniformly and conformally coat the porous and open structure of CCC with a solid lubricant trilayer of ZnO/Al 2 O 3 /ZrO 2 that results in significant improvement (65%) in fretting wear.

Swash plate for swash plate compressor and swash plate compressor

Номер: US20130174724A1

Автор: Naonari Tanigawa, Norikazu Muneda, Yoshio Oki

Принадлежит: NTN Corp

The present invention provides a swash plate, for a swash plate compressor, which is excellent in a resistance to the occurrence of seizing in a condition where an extreme pressure is generated owing to local contact between the swash plate and a shoe which slides thereon and in a condition where lubricating oil is depleted, capable of preventing cavitation-caused erosion of a resin film when the swash plate is operated at a high surface pressure and a high speed in the presence of the lubricating oil and the swash plate compressor having the swash plate. A swash plate ( 3 ) for a swash plate compressor is so constructed that inside a housing ( 1 ) where a refrigerant is present, the refrigerant is compressed and expanded by converting a rotational motion of the swash plate ( 3 ) mounted perpendicularly and obliquely on a rotational shaft ( 2 ) by directly fixing the swash plate ( 3 ) to the rotational shaft ( 2 ) or indirectly fixing the swash plate ( 3 ) to the rotational shaft ( 2 ) through a coupling member into a reciprocating motion of a piston ( 5 ) through a shoe ( 4 ) which slides on the swash plate ( 3 ) into a reciprocating motion of a piston ( 5 ) through a shoe ( 4 ) which slides on the swash plate ( 3 ). A resin film containing 25 to 70 parts by weight of fluororesin and 1 to 20 parts by weight of graphite for 100 parts by weight of matrix resin and having a tensile shear adhesive strength not less than 25 MPa is formed on a sliding contact surface of the swash plate ( 3 ) on which the shoe ( 4 ) slides.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

This patent relates to a lubricating oil with added decorated graphene nanoparticles, which is called nanolubricant. This nanolubricant has automotive and industrial applications and offers as major benefits, simultaneous improvements in the thermal, rheological and tribological properties of the lubricant used as base fluid. Additionally, this nanolubricant offers a rheopectic behavior from a specific concentration, the same behavior that gives it the ability to increase its viscosity over time provided it is subjected to a constant cutting rate. Finally, the decorated graphene may include metallic, ceramic or polymeric nanoparticles, in a concentration range of 0.5% weight/weight to 2% w/w without changing the newtonian fluid behavior of the base lubricant, whereas for concentrations greater than 2% weight/weight and up to 3% weight/weight, the aforementioned rheopectic behavior will be observed.

Coating materials with minimized lubricant demand enable optimized tribological conditions in forming flat steel products and are also unobjectionable in relation to their effects on the environment. With such coating materials, steel components can be produced by forming flat steel products in forming machines. For example, a tribologically-active layer may be produced on at least one surface of a flat steel product or a forming machine used to form the flat steel product, wherein the at least one surface comes into contact with the opposing component during forming. The tribologically-active layer may be formed by coating the at least one surface with a coating material from a group consisting of aluminum sulfate, ammonium sulfate, iron sulfate, and magnesium sulfate. The flat steel product may be inserted into the forming machine to be formed into the steel component.”

Apparatus for increasing gas components in a fluid

Номер: US20180280916A1

Автор: James Von Krosigk, Larry John Dove

Принадлежит: Individual

An apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. A variable frequency generator energizes the wire creating magnetic flux lines to pass through the fluid flow conduit. A gas injector receives fluid at the gas injector entry pressure and lowers the gas injector entry pressure of the fluid to a gas injector discharge pressure. A treatment chamber receives the fluid at a treatment chamber entry pressure and lowers the treatment chamber entry pressure to a treatment chamber discharge pressure. The apparatus causes absorption of increased gas component into the fluid by from 10% to at least 500%.
