Paper Abstract

Conventional coloured stainless steel selective absorbing surfaces produced by the chemical oxidation of stainless steel in acidic solutions deteriorate at temperatures in excess of 250°C. The as-produced surface is porous and is normally sealed with an oxide of matching refractive index. The paper compared the optical properties of these surfaces with those where the sealing process has been replaced by a metal plating process. Attention has focussed on nickel and palladium filled surfaces. The variation of optical properties with process parameters is described. The thermal stability of conventional coloured stainless steel is compared with the palladium and nickel filled surfaces.
