A UAV surface coating includes at least a bonding layer, an antioxidant layer, an oxygen-blocking propagation layer and a heat-insulation cooling layer. The coating is fabricated on a surface of a UAV machine body or covers on the surface of the UAV machine body through a composite material matrix. The UAV machine body is made of lightweight material, and the composite material matrix includes a resin-based composite matrix and a ceramic-based composite matrix. Wherein, a thickness of the bonding layer is from 20 ?m to 200 ?m, a thickness of the oxygen-blocking propagation layer is from 20 ?m to 200 ?m, and a thickness of the heat-insulation cooling layer is from 80 ?m to 1000 ?m.

The disclosure provides system, computer readable medium, and method for producing a hydroxyl radical. A plasma of a plasma gas is formed, via a controller, using a remote plasma source fluidly coupled to a gas inlet conduit coupled to a first nozzle of a processing chamber. A first gas radical is produced by flowing a first gas from a first gas source through the remote plasma source. The first gas radical is introduced into the processing chamber using the gas inlet conduit coupled to the first nozzle. A second gas from a second gas source is introduced using a plurality of second nozzles fluidly of the processing chamber. An oxidation radical is produced by mixing the first gas radical and the second gas in the processing chamber.

Disclosed is a faucet valve including: a first valve body including a first slide surface, and formed from an alumina-based sintered body; and a second valve body including a second slide surface, and formed from an alumina-based sintered body, the first and second slide surfaces at least partially being in contact with each other with water in between. At least part of the second slide body is formed from a first amorphous carbon layer. The hardness of the first amorphous carbon layer is equal to or less than that of the alumina-based sintered body forming the first valve body. In the first amorphous carbon layer, a ratio (ID/IG) of a D peak to a G peak, measured by Raman spectroscopy, is greater than 0.5 but less than 1.9.

A technique may include controlling a vacuum pump to evacuate a vacuum chamber to high vacuum; controlling a plasma spray device to deposit a coating on a substrate in the vacuum chamber using plasma spray physical vapor deposition; and controlling a source of a reactive gaseous species to introduce a controlled amount of the reactive gaseous species into the vacuum chamber during the plasma spray physical vapor deposition process. The reactive gaseous species may react with at least one constituent of the coating to form a dispersed phase in at least part of the coating.

A method to apply nano-crystalline diamond onto a selected substrate, including preparing Nanodiamond slurry of Nanodiamond particles dispersed in a medium. The medium may include a liquid or a sol-gel. The selected substrate is immersed in the Nanodiamond slurry for a predetermined period of time. Then the substrate is removed from the slurry. The substrate is then dried with a flow of inert gas. The substrate is left coated with a coating of the nanodiamond particles that are highly adherently held by van der Waals forces.
