Abstract
A uniform, thick film is formed by applying a powdered metal, alloy, sulfide of metal or glass each particle of which is coated with plastics 1-15% by weight, preferably the particle surfaces having been treated with an aliphatic acid or a silane-type surface-treating agent and the plastics including an organic peroxide, to a substrate by electrostatic powder spraying, fluidized bed coating, electrophoretic deposition, or by electrostatic fluidization, and fixing the layer thus provided on the substrate with heating to such extent that the plastic ingredient is fused or volatilized, to finally produce the desired film. The materials having such films fixed thereon have a wide application for interior building and glass-lining and as material of bearings.
