Abstract
900,504. Electrophoretic deposition of conductive layers on oxidized metallic surfaces. SIEMENS & HALSKE A.G. Aug. 5, 1960 [Aug. 5, 1959], No. 27204/60. Class 41. A conductive layer is electrophoretically produced on an oxidized metallic surface whilst oxygen bubbles are liberated at the surface. The method may be used in producing electrolytic capacitors. As shown, a graphite layer 4 is being anaphoretically deposited on an anodically produced oxide surface layer 2 on an aluminium foil 1. Pores in the oxide layer are filled with oxygen bubbles 3, 3<SP>1</SP>, 3<SP>11</SP>, 3<SP>111</SP> by reason of a positive potential applied thereto, the bubbles preventing graphite particles from penetrating into the pores. The gas-filled pores become slowly covered by graphite as indicated at 3<SP>1</SP> and 3<SP>111</SP>. In another embodiment, graphite is anaphoretically deposited on oxidized aluminium wires. Successive layers of graphite may be applied. Silver or other metals may be subsequently deposited on the conductive layer.
