The invention discloses a wear-resistant alloy material, in particular a processing method of wear-resistant and high temperature-resistant nickel-based alloy sleeve. The alloy composition of the raw material weight percentage is: nickel 53-66%, chromium 20-25%, copper 3-5.8%, holmium 0.05-0.15%, manganese 10-12%, titanium 0.25-0.35%, cobalt 0.4-0.6%, and the remaining amount is rare earth. As the addition of chromium and copper in the nickel-based alloy for axle sleeve of the present invention increases the tensile strength and hardness of the alloy, increases the hardness and toughness of the alloy dramatically, holmium can improve the corrosion resistance of the alloy, cobalt can increase the hard point of the alloy, greatly improves the wear resistance, titanium can refine the grain, improve the strength and toughness of the alloy, especially by adding a large number of rare earth elements. Its quality is higher. By choosing suitable material and matching relationship, the sleeve has good hardness, strength and toughness. It can achieve good mechanical properties, long service life, better economy and comprehensive mechanical properties.
