Abstract
An optically black coating with improved infrared absorption is disclosed along with a process for formation therefor. An anodizable substrate is first treated in a surface modification step prior to anodizing to produce major surface modifications at least about 100 microns in width and at least about 50 microns in depth. Preferably, the depth is at least about 1/2 the width, and the modifications are present in a random series of irregularly sized modifications having widths from about 100 microns to about 1,000 microns and depths from about 50 microns to about 750 microns. A second aspect involves the use of steam for sealing the anodized surface.
