Title: Corrosion resistant solar mirror

Abstract

A reflective article includes a transparent substrate having a first major surface and a second major surface. A base coat is formed over at least a portion of the second major surface. A primary reflective coating having at least one metallic layer is formed over at least a portion of the base coat. A protective coating is formed over at least a portion of the primary reflective coating. The article further includes a solar cell and an anode, with the solar cell connected to the metallic layer and the anode.

  • A corrosion and ultra violet-resistant silver mirror for use in solar reflectors; the silver layer having a film-forming protective polymer bonded thereto, and a protective shield overlay comprising a transparent multipolymer film that incorporates a UV absorber. The corrosion and ultraviolet resistant silver mirror retains spectral hemispherical reflectance and high optical clarity throughout the UV and visible spectrum when used in solar reflectors.
  • An improved high energy laser (HEL) mirror is provided wherein the internal surfaces of the molybdenum structure of the mirror defining passageways for water coolant flow are plated with deposition (CVD) techniques described by the invention herein. The mirror is thereby made resistant to the corrosive action of the circulating coolant water on the molybdenum structure comprising the laser mirror.
  • A system for coating a surface comprises providing a source of amorphous metal, providing ceramic particles, and applying the amorphous metal and the ceramic particles to the surface by a spray. The coating comprises a composite material made of amorphous metal that contains one or more of the following elements in the specified range of composition: yttrium (.gtoreq.1 atomic %), chromium (14 to 18 atomic %), molybdenum (.gtoreq.7 atomic %), tungsten (.gtoreq.1 atomic %), boron (.ltoreq.5 atomic %), or carbon (.gtoreq.4 atomic %).

  • The nickel alloys applied are composed of 15 to 22% molybdenum, 6 to 8% chromium, 0.02 to 0.5% carbon, 0 to less than 6% iron, 0 to 4% vanadium, niobium, tantalum and/or tungsten. Means for the desulphurization, desoxidization, and the improvement of the forging and rolling properties are included. (Gmelin Inst)
