“…According to the same three-point bending test, both maximum load and displacement to failure of the highstrength steel were reduced by the zinc plating, and hydrogen embrittlement was induced. 13) These results indicate that hydrogen is supplied in the same manner by the zinc plating, but the action of hydrogen differs depending on the substrate material. Both Ni-P and zinc platings on high-strength steels accelerate the hydrogen embrittlement.…”

In this study, 6061-T6 aluminum alloys were plated with electroless Ni-P with different phosphorus content and three-point bending and rotating bending fatigue tests. The effects of hydrogen due to plating on mechanical properties were investigated. It was shown that the ductility decreased immediately after low-phosphorus type and high-phosphorus type Ni-P plating by three-point bending test because a hydrogen was introduced into the alloys. The fatigue strength of the low-phosphorus type Ni-P plated specimen was higher than that of the un-treated specimen, while that of the high-phosphorus type plated specimen was much lower. It is clear that the fatigue strength differs greatly depending on the phosphorus content in the plating film. 6061-T6 aluminum alloy have been reported to exhibit no hydrogen embrittlement in low strain rate tensile tests under wet condition. However, it was found that hydrogen embrittlement occurred when 6061-T6 aluminum alloy was plated with the high-phosphorus type electroless Ni-P and fatigue-tested on rotating bending machine.
