The porous Ni-Cr-Mo-Cu alloys were fabricated by an activation reaction sintering technique. The effects of Cr content varied from 10 to 30 wt-% on the corrosion performance of porous alloys in 10 wt-% H2SO4 solution were evaluated using weight-loss method and electrochemical techniques. The structural morphology, phase constitution and elemental distribution were characterized by scanning electron microscopy (SEM), X-Ray diffraction analysis, energy dispersive spectrometer and X-ray photoelectron spectroscopy (XPS). The results indicate that porous Ni-Cr-Mo-Cu alloys possess excellent corrosi...
