ABSTRACT:
A method and apparatus for coating a metallic substrate with an oily substance. Use is made of a support member having a ceramic coating comprising an oxide ceramic material, onto which is applied the oily substance to form a film of the oily substance uniformly covering the surface of the ceramic coating, the film of oily substance breaking down into micro-droplets having substantially uniform size and distribution. The micro-droplets of oily substance are thereafter transferred onto a surface of the metallic substrate without substantially altering the size and distribution of the micro-droplets, thereby coating the surface of the metallic substrate with the oily substance. The invention is particularly useful for coating the positive electrode of a high-speed electrocoagulation printing apparatus with an olefinic substance containing a metal oxide.
