Amorphous coatings and coated articles having amorphous coatings are disclosed. The amorphous coating comprises a first layer and a second layer, the first layer being proximal to a metal substrate compared to the second layer, the second layer being distal from the metal substrate compared to the first layer. The first layer and the second layer comprise carbon, hydrogen, and silicon. The first layer further comprises oxygen.

Amorphous coating

A wear coating is disclosed that includes a layer treated by a trifunctional organosilane. An article is also disclosed, the article having a surface to which the wear coating is applied. A method of applying the wear coating is also disclosed. In some embodiments, the organosilane is trimethylsilane and the wear coating is applied by chemical vapor deposition, followed by heat treating the wear coating in the presence of the trimethylsilane.

Wear resistant coating, article, and method

Functionalized substrates and method of passivating the surface of a substrate to improve the surface by imparting desirable surface properties to improve the performance of a surface, the method steps including exposing the substrate to a chemical vapor deposition process to coat the substrate with silicon, and functionalizing the coated surface by exposing the substrate surface to a binding reagent having at least one unsaturated hydrocarbon group.

Process for the modification of substrate surfaces through the deposition of amorphous silicon layers followed by surface functionalization with organic molecules and functionalized structures

A method of passivating the surface of a substrate to protect the surface against corrosion, the surface effects on a vacuum environment, or both. The substrate surface is placed in a treatment environment and is first dehydrated and then the environment is evacuated. A silicon hydride gas is introduced into the treatment environment, which may be heated prior to the introduction of the gas. The substrate and silicon hydride gas contained therein are heated, if the treatment environment was not already heated prior to the introduction of the gas and pressurized to decompose the gas. A layer of silicon is deposited on the substrate surface. The duration of the silicon depositing step is controlled to prevent the formation of silicon dust in the treatment environment. The substrate is then cooled and held at a cooled temperature to optimize surface conditions for subsequent depositions, and the treatment environment is purged with an inert gas to remove the silicon hydride gas. The substrate is cycled through the silicon depositing step until the surface of the substrate is covered with a layer of silicon. The treatment environment is then evacuated and the substrate cooled to room temperature.
