Abstract

The invention discloses a novel special material for a powder metallurgy gear case. The novel special material for the powder metallurgy gear case comprises the following components of, by weight, 7-25% of aluminum nitride ceramic powder, 0.5-3% of nickel powder, 0.1-2% of aluminum powder, 0.5-3% of graphite, 0.2-2.5% of poly(isobutyl vinyl ether), 0.2-2.5% of zinc stearate, and the balance of iron powder; and the sum of the weight percentages of the components is 100%. A metal ceramic compound is formed by the iron powder and the aluminum nitride ceramic powder, through addition of a trace amount of the nickel powder and a trace amount of the aluminum powder, refining of a two-phase micro-interface is promoted, and wear resistance and strength of the manufactured gear case are further improved.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to a special material for powder metallurgy gearboxes. Background technique [0002] Powder metallurgy is a process technology that uses metal powder (or a mixture of metal powder and non-metal powder) as a raw material, after forming and sintering, to manufacture metal materials and various types of products. The production process of powder metallurgy parts has the advantages of rapid prototyping capability of complex parts and high utilization rate of materials. [0003] There are many types of powder metallurgy products, including powder metallurgy gearboxes. The existing powder metallurgy gearbox materials have poor wear resistance and low strength, which need to be improved. Contents of the invention [0004] The object of the present invention is to provide a powder metallurgy material capable of manufacturing high-strength and wear-resistant gear boxes. [0005] In orde...
