Abstract
Metal tubing, preferably of square cross section, is employed as a cathode in an electrolytic cell. A layer of electrically nonconductive boron carbide particles is deposited on the surface of the tubing facing the anode and copper is electroplated through the layer of particles, following which the tubing is rotated to expose another face. In another system, tubes are arranged about the inner surface of a rotatable drum with a coaxial copper anode. The drum is filled with electrolyte and spun so that centrifugal force holds the boron carbide particles on the surfaces of the tubes and aids electrodeposition. Alternatively, a rotating cylindrical copper anode can be used with the tubing at the center.
