Abstract: Disclosed is a method of forming a hard, carbonaceous film on a substrate and the hard carbonaceous film formed thereby. The hard carbonaceous film is formed by decomposing a gaseous hydrocarbon having carbon atoms tetrahedrally coordinated to its nearest neighbors through carbon-carbon single bonds. The gaseous hydrocarbon is decomposed in a radio frequency maintained plasma and the plasma decomposition products are deposited on a cathodic substrate. Optionally, fluorocarbons may be present in a decomposition gas.

Abstract: An article of manufacture includes a substrate carrying at least two coating layers, one layer being of approximately quarter wave optical thickness, the other layer of approximately two quarter wave optical thickness, with the layers alternating between a material such as a dielectric having a first index of refraction and a second material such as a dielectric having a second index of refraction lower than the first index of refraction. These layers form a filtering system which removes narrow bands of light such as laser wavelengths by efficient reflection while permitting the remainder of the light spectrum to pass through the article. The coating layers have optical thicknesses and indices of refraction appropriate to reflect more than 99% of incident light at one or more predetermined wavelengths of light in the range of about 300 to about 1,200 nanometers and to transmit a substantial amount of all other incident light in the range.

Abstract: This invention describes a platable plastic material that uses a phosphide compound as a filler at levels of 5 to 40 weight percent. The phosphide filler used in this way has good dielectric properties and is non-conductive, but the phosphide provides coupling sites for a conductive plating to initiate and to bond to the filler and thus to the plastic. Surface treatment of the plastic may be needed to expose the particles but this invention removes requirements for catalytic treatment with noble metal chlorides and relies on bonding mechanisms other than the mechanical grip on a rough surface.
