Abstract
A band of material is formed by plating the material onto a cylindrical cathode sandwiched between a pair of insulating end pieces and is supported in a plating bath spaced a short distance from an anode. The cathode is rotated about its axis to provide uniform, reproducible mass transport to the plating surface. In order to determine the tensile properties of the plated material, the band is removed from the cathode and pulled apart in a tensile machine. During tensile testing, the band is held using a pair of pins and clevis, or it is formed into a strip and gripped in a standard fixture. In order to determine the stress condition of the plated material, the band is cut open and its change in diameter measured.
