Both oxide removal and low surface roughness was achieved at hot rolled Ni-45.0at.%Ti shape memory alloy (SMA) surface using a nanosecond pulsed Nd:YAG laser. The oxidized and polished surfaces were analyzed by White-Light Interference (WLI), Focus ion beam (FIB) and energy dispersive spectrometer (...
