Abstract

The invention proposes a high-wear-resistant composite alloy ring and its preparation process, which includes an annular alloy steel base material, a transitional infiltrated layer, and a hard alloy cladding layer. The transitional infiltrated layer has a thickness of 0.2-0.7mm and is hard The thickness of the alloy cladding layer is 1-3mm. Through reasonable raw material ratio and coating selection, arc-added glow ion plating technology and synchronous laser cladding technology are used to treat the base material respectively, and a composite alloy with three-layer structure is obtained. The ring, base material, permeable layer and cladding layer are well combined, have excellent wear resistance, corrosion resistance, toughness and stability, high surface density, significantly improved mechanical properties, and effectively prolong the service life of the product.
