Abstract:
1. A method for producing a plated low alloy strength steel having superior corrosion and low hydrogen embrittlement properties, the method comprising: electroplating a zinc/nickel coating on a low alloy, high strength steel from an alkaline plating bath, wherein the bath comprises zinc and nickel at a level to produce a plated coating containing 85-95% by weight zinc and 5-15% by weight nickel, wherein the bath further comprises an effective amount of a nickel complexing agent; wherein the bath further comprises less than 100 ppm of total organic material other than the complexing agent; and wherein the coating has a dense, porous morphology that provides corrosive resistance on account of its density and resistance to hydrogen embrittlement on account of its porosity.
