The invention discloses an anti-wear alloy layer based on a high boron iron base and a method for preparing a composite anti-wear part. The anti-wear alloy layer is a high boron iron-based alloy, andcomprises, by mass, 0.2%-0.3% of C, 1.20%-1.60% of B, 0.4%-0.9% of Si, 0.6%-1.1% of Mn, 8.3%-10.5% of Ni, 17.0%-20.0% of Cr, 0.08%-0.15% of Ce, 0.10%-0.15% of Ti, 0.04%-0.08% of N, less than 0.05% ofP, less than 0.05% of S, and the balance Fe and other unavoidable impurities. By adopting an advanced resin sand production line and an electric-furnace smelting technology, surface alloying is achieved through a cast infiltration technology to replace heat treatment surface strengthening, the elements of titanium, zirconium, tantalum and tungsten are evenly mixed with inorganic salt to be fixed in a casting mold, metal liquid is casted, and the composite anti-wear part is obtained after cooling and unpacking. The anti-wear alloy layer based on the high boron iron base and the method for preparing the composite anti-wear part can improve the toughness and the surface hardness of the high boron iron-based alloy anti-wear part, and can prolong the service life of the high boron iron-based alloy anti-wear part.
