摘要: 以等離子弧為熱源,采用類似激光表面改性的辦法,研究了重熔處理對Ni基自熔合金組織和耐磨性的影響。經等離子弧掃描重熔,噴焊層表面形成重熔激冷層,該層基體組織由γ-Ni轉變為化合物Cr_0.7Fe_0.36Ni_2.90,并形成晶粒度很小的微晶組織。重熔后試樣的耐磨粒磨損與粘著磨損性能提高,且880W重熔較440W重熔試樣的耐磨粒磨損性能提高程度更大。

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.
