Cadmium Coatings Containing Dispersed Nickel Particles for the Protection of High Strength Steels against Corrosion

Abstract

Slow strain rate and sustained load tensile tests on 300M and NCMV alloys have shown that the susceptibility of these high strength steels to hydrogen embrittlement during plating with cadmium, can be considerably reduced in both as-deposited and baked conditions by co-depositing nickel particles with the cadmium. The nickel particles are thought to preferentially absorb hydrogen both during plating and in the post-plate baking treatment. The corrosion resistance of Cd/Ni composite coated steel panels in outdoor exposure tests appears to be better than simple cadmium-plated steel panels under the same conditions.
