NOVELTY - Coating a substrate involves adding ion erosion resistant particles, conductive particles, and a binder to an electrophoretic solution in an electrophoretic deposition apparatus including the substrate and a cathode spaced from the substrate. A current is applied to the substrate and cathode to deposit a first layer coating including the erosion resistant particles, conductive particles, and binder onto the substrate. A low work function material is added to an electrolyte solution in an electrolytic deposition apparatus including the substrate and a cathode spaced from the substrate. A current is applied to the substrate and the cathode to deposit a second layer coating including the low work function material onto the substrate. USE - Method for coating substrate for ion erosion resistance and passive electron emission during space weather exposure of spacecraft components, satellites, orbiting platforms, and solar arrays. ADVANTAGE - The carbon nanotubes and binder used in the method provide atomic oxygen shielding and other properties, erosion resistance and protection from adverse effects of spacecraft charging, and it improves durability/resistance to ion erosion.
