Abstract
A hard iron alloy plate is electrodeposited from a high-conductivity aqueous plating solution containing ferrous ions and cobalt ions. The product plate is composed of up to 6 percent cobalt and the balance iron and is characterized by microscopic cracks perpendicular to the plate surface and effective to reduce the residual tensile stress to below about 60 MPa.
