Abstract

Scattering characteristics of metal surfaces sprayed with Si₃N₄ nano-powder and plastic powder mixture were evaluated by an angle-resolved reflectometer. The preliminary results obtained seem to indicate that the characterization of the angle-resolved scattering distribution can be controlled as needed by selecting the sample surface material and/or its mixture. The property may be used in analysis of surface signatures. The relation between the angular distribution of scattering-cross section and the statistical characteristics of random height of microrough metal surface is also discussed in this paper.
