Abstract

Electrodeposition of metals form aqueous solutions (eg, electroplating ) is frequently accompanied, by the discharge of hydrogen ions(in acidic solutions) or water molecules ( in alkaline electrolytes). The atomic hydrogen produced thus may partly diffuse into the interior of the substrate and when this is absorbed by iron/steel substrate, it has detrimental effects on the mechanical properties of the steel, leading to ahydrogen embrittlement. Steels, particularly the high strength steels, are prone to hydrogen embrittlement. In view of the increasing applications of high strength steels in variousindustries, particularly in the aircraft manufacture, there has been renewed interest in the studiesonhydrogen embrittlement during electroplating of metals. In this review, the author summarizes the reports on hydrogen embrittlement during preplating of metals. In this review , the author sumamrizes the hydrogen embrittlement during electroplating of metals. In this review , the author summarizes the reports on hydrogen embrittlement during preplating operations and electroplating of metals like copper, nickel, tin, zinc ,cadimum and chromium. Finally, the effect of degassing by baking to deembrittle the plated high tensile steels and mechanism of hydrogen embrittlement are briefly indicated.
