Experimental Study on the Plasma-Arc Remelting Treatment of Ni-Based PTAW Cladding

    Graphical Abstract
    • Abstract
  • The effect of plasma arc remelting treatment on the microstructure and wear resistance of overlay is investigated and discussed.With plasma are remelting process, a remelting-chilling layer formed on the overlay surface.In the layer,the matrix structure transormed from γ-Ni to Cr0.7Fe0.36Ni2.90,and fine crystallite grains were obtained. Both abrasive and adhesive wear resistance were maised by plasma the remelting process.
