Electropolishing of inclined cylinders under natural convection conditions
The rates of electropolishing of inclined copper cylinders in H3PO4 were studied by measuring the limiting current of the process. The variables studied were the angle of inclination of the cylinder and the H3PO4 concentration. The limiting current increased as the cylinder was inclined from the vertical position, reached a maximum value at an angle of 45°, and then decreased slightly on further inclination towards the horizontal position. The difference between the maximum limiting current at 45° and the minimum limiting current at 90° (vertical position) ranges from 30% to 47% depending on the H3PO4 concentration.
