The present disclosure provides an aluminum alloy coating, an aluminum alloy wheel hub and a spraying method of an aluminum alloy wheel hub. The aluminum alloy coating includes a base powder layer, a main body layer and a transparent powder layer from inside to outside. The main body layer includes at least two prime coat layers and at least two colored paint layers which are superposed in a preset order.

Embodiments described herein provide a gas supply system for reducing purge time and increasing processing throughput, and an atomic layer deposition (ALD) chamber having the same. The gas supply system includes an inert gas line and a precursor supply line. The inert gas line is configured to be coupled to an inlet of the chamber separate from the precursor supply line. Therefore, the inert gas is supplied concurrently to the precursor supply line and the processing region of the chamber such that total purge time is reduced. The reduction of the total purge time due to the gas supply system increases purge efficiency and increases processing throughput. Furthermore, the gas supply system allows inert gas to be utilized as a dilution gas during flow of precursors.

A method of manufacturing a tubular member for an exhaust gas treatment device according to at least one embodiment of the present invention, the tubular member including a tubular main body made of a metal and an insulating layer formed on at least an inner peripheral surface of the tubular main body, the insulating layer containing glass, includes steps of: forming a coating film by spraying a coating liquid for insulating layer formation onto the inner peripheral surface of the tubular main body; and firing the coating film to obtain the insulating layer. The spraying is performed while the tubular main body is rotated with a length direction thereof being a rotation axis.

A post-cure inflation machine for processing a tire may include a tire holder shaft. The tire holder shaft may include a chuck to secure the tire to the tire holder shaft. A hollow passage may be defined in the tire holder shaft. A spray nozzle may be connected to a spray shaft that is telescopically disposed in the hollow passage of the tire holder shaft. The spray nozzle may extend to spray an air barrier material onto the tire.

Methods and apparatus for vapor deposition of an organic film are configured to vaporize an organic reactant at a first temperature, transport the vapor to a reaction chamber housing a substrate, and maintain the substrate at a lower temperature than the vaporization temperature. Alternating contact of the substrate with the organic reactant and a second reactant in a sequential deposition sequence can result in bottom-up filling of voids and trenches with organic film in a manner otherwise difficult to achieve.

According to the invention there is disclosed a dispenser device for dispensing a medicament, the device comprising at least one component having a coating that comes into contact with the medicament during storage or use of the device on at least one surface thereof, the coating comprising a cross-linked non-diamond like carbon layer comprising 50 At % hydrogen or less and having an interface with the underlying surface of the component.

A mechanism for applying a predetermined pattern of material onto an elongate tubular substrate includes a first motor, an engagement member rotatable by the first motor and configured to reversibly grasp an elongate member, such that rotation of the first motor rotates the elongate member around its longitudinal axis, a fluid dispenser configured to dispense a fluid having a first, flowable state, the fluid dispenser including an elongate dispensing conduit having a distal end having an orifice, the orifice configured to be placed adjacent a surface of the elongate member, a second motor configured to move at least one of the elongate member or the elongate dispensing conduit such that the orifice changes its relative orientation along the longitudinal axis of the elongate member, and wherein the distal end of the elongate dispensing conduit is configured to apply a bias on the surface of the elongate member.

A medical appliance or prosthesis may comprise one or more layers of rotational spun nanofibers, including rotational spun polymers. The rotational spun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Rotational spun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis. Additionally, one or more cuffs may be configured to allow tissue ingrowth to anchor the prosthesis.

An optical device includes a substrate, a first surface-relief grating including grooves and ridges formed on or in the substrate, a first overcoat layer in the grooves of the first surface-relief grating, and a first antireflective layer on the first overcoat layer. The ridges of the first surface-relief grating include high-refractive index, photoactive metal oxide nanoparticles and a material of the first overcoat layer in regions between the metal oxide nanoparticles, or the first overcoat layer includes the metal oxide nanoparticles and a material of the first antireflective layer in regions between the metal oxide nanoparticles. Methods of fabricating the optical device are also described.

Systems having one or more features that are advantageous for depositing fluorinated polymeric coatings on substrates, and methods of employing such systems to deposit such coatings, are generally provided.
