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 Cr_0.7Fe_0.36Ni_2.90,and fine crystallite grains were obtained. Both abrasive and adhesive wear resistance were maised by plasma the remelting process.
