【Abstract】 Hydrogen content in metal with zinc\|nickel alloy plating was studied by an electrochemical hydrogen permeation technique, and the hydrogen embrittlement behaviors of plating were evaluated to obtain two electroplating baths which could decrease the hydrogen embrittlement of high strength steel. Favorable Zn\|Ni alloy plating had been obtained in chloride\|sulfate solution or chloride solution with additive B. The results were approved by the notched tensile tests.更多还原
