Abstract

The wear and corrosion of rare earth NiCrMoY alloy manufactured by atomization and oxygen-acetylene flame spray and high frequency induction remelting technique are investigated by a combination of scanning electron microscopy (SEM), energy spectrum, X-ray diffraction meter (XRD), uniform corrosion method of laboratory immersion test, anodic polarization curve of three electrodes potentiodynamic scan. The results indicate that Corrosion rate of NiCrMoY alloy coatings is better than that of Ni60A coatings in HCl, H2SO4, HNO3 and artificial seawater, and its wear is much better than those of Ni60A coatings.
