摘要
Nitrogen and aluminum concentration profiles in the near surface region of the Ti6Al4V-ELI alloy plasma nitrided under controlled processing conditions are studied by nuclear reactions analysis (NRA), The results are complemented by compound identification using grazing angle X-ray diffraction (GXRD) and visual inspection of the microstructure by backscattered electron (BSE) scanning microscopy. The layered structure of titanium nitrides near the surface of the alloy is described as a function of the nitriding temperature and the adequacy of the NRA technique is discussed.
