摘要：

Specimens of a Ni-rich NiTi alloy was electrolytically pre-charged with hydrogen over a wide range of current densities (0.0001-0.1 A/cm(2)). The cavitation erosion resistance of all the hydrogen-charged specimens were significantly reduced. The decrease in resistance was attributed to the formation of hydride at the grain boundaries.
