ABSTRACT:
A method for preparing a metallized surface that possesses gradients in surface topography includes obliquely depositing a metal from a metal source onto a surface of a support. The surface of the support includes a first end, a second end, and a region between the first and second ends. The second end of the surface is located nearer to the metal source than is the first end, and the metal is deposited onto the first end of the surface at a first angle of incidence and the metal is deposited onto the second end of the surface at a second angle of incidence. The first angle of incidence is greater than the second angle of incidence, and the metal is deposited onto the region between the first and second ends at angles of incidence that vary over the region to produce the metallized surface with gradients in surface topography. The angles of incidence are measured from the normal of the support.
