Reflektierende verschleissgeschuetzte optische Schichten auf kohlenstoffaserverstaerkten Kunststoffen fuer inertionsarme Optiksysteme (ROKKIO) Abschlussbericht

Abstract

The study includes the preparation of polishable nickel layers on CFK/CFC substances, characterization of the systems CFK/CFC substrate-plasma sputtered interface - polished nickel layer - wear resistant coating by means of microscope surface analytics, preparation of functional and wear resistant coating and long-term stability of the prepared systems. Polishable nickel layer chemically deposited from a complex electrolyte system proved to be superior to galvanic nickel deposition and resulted in wear and corrosion resistant coatings even with complicated shaped substrates. Optical coatings were prepared by plasma ion assisted deposition. Metallization of CFK substrates with Ni/Al interfaces were achieved with the matrix types V (vinyl ester) and H (a high-temperature resistant matrix) by chemical deposition resulting in polishable, shiny surfaces which are suited for subsequent coating. Application in optical systems is limited by high densities of surface defects and by deformation of the optical surface under the influence of moisture and temperature.
