1. A coated article including a non-planar article surface and a coating on the article surface comprising a plurality of non-spherical particles disposed in the coating on the article surface in a non-metallic matrix about the particles, each particle having a major dimension, the combination in which:

  • the coating is integral with the article surface;

    an average of at least about 50% of the major dimensions of the particles are oriented generally along the non-planar article surface in respect to which the particle is disposed;

    the article surface is of a complex, three dimensional non-planar shape; and

    , the non-spherical particles are metallic flakes having an aspect ratio in the range of about 10-100 in the non-metallic matrix to enable positioning of the average of at least 50% of the major dimensions of the metallic flakes along the complex, three dimensional, non-planar shape of the article surface.
