Abstract

The invention discloses a copperizing solvent and a preparation method thereof, belonging to the technical field of powder metallurgy. The copperizing solvent comprises the following components in percentage by weight: 0.5-10% of one or a plurality of Fe, Zn, Mn, Sn, P and Cr, and 90-99.5% of Cu The preparation method is as follows: weighting raw materials at ratio, adding ceramic balls or stainless steel balls and diffusion accelerating agent; after mixing, sending powder into a hydrogen reduction furnace for diffusion at the diffusion temperature of 300-1000 DEG C for 0.5-25h; cooling, discharging, breaking, screening and collecting; and adding lubricant for blending. The copperizing solvent prepared with the preparation method has the characteristics of favourable forming property, high infiltration efficiency, no erosion and small residue and obviously improves material density and mechanical property. The method has simple flow, required equipment is easy to operate and the coppering solvent can be produced in batch.

Description

technical field [0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to a copper infiltrating agent and a preparation method thereof. Background technique [0002] At present, due to its low cost and easy processing, iron-based powder metallurgy parts are more and more widely used in industrial production, especially in the automobile industry. Commonly used parts include gears, cams, valve seats, exhaust valve seats, etc. Due to their harsh service conditions, these parts have high performance requirements, which must not only be wear-resistant and corrosion-resistant, but also maintain high strength and hardness. However, powder metallurgy sintered steel contains a large number of pores, which affect the tensile strength, elastic modulus, elongation, impact toughness, fracture toughness, fatigue strength and hardness of sintered steel. Therefore, the best way to improve the mechanical properties of sintered steel One of the e...
