    摘要: A method of forming a hydrogenated amorphous germanium carbon (α-GeCx:H) film on a surface of an infrared (IR) transmissive material such as a chalcogenide is provided. The method includes positioning an IR transmissive material in a reactor chamber of a parallel plate plasma reactor and thereafter depositing a hydrogenated amorphous germanium carbon (α-GeCx:H) film on a surface of the IR transmissive material. The depositing is performed at a substrate temperature of about 130° C. or less and in the presence of a plasma which is derived from a gas mixture including a source of germanium, an inert gas, and optionally hydrogen. Optical transmissive components, such as IR sensors and windows, that have improved abrasion-resistance are also provided.

    摘要: The present invention provides tough, high modulus, low density thermoset polyurethane compositions which are useful in general as, for example, cast structural materials and in a preferred embodiment can be cured directly onto an aircraft engine fan blade, thereby providing a lighter blade, without concomitant loss in structural integrity or blade performance due to, for example, resistance to foreign object impacts and fuel efficiency. In a preferred embodiment, the composition is comprised of bis-amine compounds reacted with isocyanate-functional polyether polymers in the presence of hollow polymeric microspheres. The thermoset polymer compositions are formed by casting into a mold which is formed by a cavity within the metallic or composite fan blade or guide vane in the form of a pocket and a removable caul sheet. After the elastomeric polyurethane foam is injected through at least one injector port into the mold, the foam is cured.
