A method to quantitatively analyze the defects formed by the hydrogen evolution during electroplating was suggested based on the theoretical approach of the small angle neutron scattering technique. In case of trivalent chrome layers, an isolated defect size due to the hydrogen evolution was about 40 nm. Direct and pulse plating conditions gave the average defect size of about 4.9 and 4.5 μm with rod or calabash shape, respectively. Current density change of the pulse plating from 1.5 A/dm2 to 2.0 A/dm2 enlarged the average defect size from 3.3 to 7.8 μm. The defect morphology like rod or calabash was originated by inter-connecting the isolated defects. Small angle neutron scattering was useful to quantitatively evaluate defect morphology of the deposit.
