Abstract

The invention discloses an amorphous diffusion alloy and a preparation method thereof. The amorphous diffusion alloy is prepared from nickel coated titanium carbide, boron carbide, mixed rare earth, ferrotitanium powder, superfine high-carbon chromium iron powder, silicon carbide whiskers, boron nitride, lanthanum oxide, cerium oxide, zirconium oxide, copper powder, high-nitrogen ferrochrome, cobalt powder, manganese powder, tungsten powder, nanometer titanium oxide, and the balance of superfine iron powder, wherein the mixed rare earth is heavy rare earth or light rare earth. The amorphous diffusion alloy is mainly used in iron-based powder metallurgy products, can improve the impact, tensile fatigue, wear and heat resistance of the products, can partially or completely substitute noble metal elements, and reduces the cost of the products.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to an amorphous diffusion alloy and a preparation method thereof. Background technique [0002] Powder metallurgy is a processing method for preparing metal powder and making the mixture of metal powder or non-metal powder into products through forming and sintering processes. It can not only produce special materials that are difficult to produce by ordinary smelting methods, but also manufacture various A kind of precision mechanical parts, saving labor and materials. However, the cost of the mold and metal powder is relatively high, and it should not be used when the batch size is small or the product size is too large. Compared with traditional material technology, powder metallurgy materials and processes have the following characteristics: 1. The powder metallurgy process is carried out at a temperature lower than the melting point of the base metal, so a variety of...
