According to our previous work on the corrosion behavior of zinc-nickel alloy electroplated steel sheets in aqueous solutions, corrosion induces the formation of grooves that reach to the underlying steel. The corrosion grooves, which are thought to be caused by corrosion cracking, may cause deteriorating in corrosion resistance.<br>In the present study, a method for measuring the fracture strength of zinc-nickel alloy electroplating films was established as a part of fundamental study toward improving corrosion resistance through suppression of corrosion groove formation. Fracture strength was determined by detection of acoustic emissions generated by film cracking during tensile testing of specimens. The fracture strength of zinc-nickel alloy films varied depending on plating current density.
