Evaluation of hydrogen embrittlement of three aluminum alloys by three-point bending test affected by three types of plating

Hydrogen embrittlement affected by three types of plating (low-P and high-P electroless Ni-P electrolytic Zn-platin) was investigated means slow-strain-rate three-point bending test on aluminum alloys (2017-T3, 6061-T6 7075-T651). generated the zinc absorbed alloy substrates, trap sites in substrates for hydrogen differed between plating. able to be evaluated tests plated alloys. Zinc did not cause all alloys, but induced only alloy. The result corresponds highest amount desorbed below 240°C than other
