| description | In this study, a WC-reinforced Ni-based surfacing layer was prepared on Q235 steel plate by plasma arc welding. The effects of nano-Y<sub>2</sub>O<sub>3</sub> with different contents (0 wt.%, 0.4 wt.%, 0.8 wt.%, 1.2 wt.%, and 1.6 wt.%) on the microstructure, phase composition, microhardness, and wear resistance of the surfacing layer were studied by scanning electron microscope (SEM), energy dispersive spectrometer (EDS), X-ray diffraction (XRD), microhardness test, and pin-on-disk test. The results show that the phase composition of the surfacing layer was γ-Ni, FeNi<sub>3</sub> solid solution, WC, W<sub>2</sub>C, M<sub>23</sub>C6, M<sub>6</sub>C, Cr<sub>7</sub>C<sub>3</sub>, and other carbides. When the addition of nano-Y<sub>2</sub>O<sub>3</sub> was 1.2 wt.%, it has a good improvement on microstructure grain refinement and carbide hard-phase increase. Compared with other contents, 1.2 wt.% nano-Y<sub>2</sub>O<sub>3</sub> surfacing layer has the highest microhardness and the lowest friction coefficient and wear loss. At this time, the wear mechanism is abrasive wear accompanied by slight adhesive wear. |
