Abstract
An article of manufacture comprises a substrate and an optically black surface on the substrate and having an absorptivity of more than about 0.89 and an emissivity more than about 0.86. The surface comprises boron particles plasma spray applied to the substrate using a powder selected from the group consisting of crystalline boron having a particle size finer than about 200 mesh and amorphous boron.
