Porous Ni-Cr-Mo-Cu alloys were prepared via reaction synthesis of mixed powders. Electrochemical performance test and weight-loss method were used to evaluate the effects of chromium content in the range of 10 similar to 30 wt% on the alloys corrosion performance in 30 wt% H3PO4 solution. The microstructure, element valence and phase composition of the porous Ni-Cr-Mo-Cu alloys were characterized via scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and x-ray diffraction analysis (XRD), respectively. And the results show that the alloys exhibited serviceable corrosion ...
