Abstract
The invention discloses a high-strength wear-resistant powder metallurgy gear material. The high-strength wear-resistant powder metallurgy gear material comprises the following components of, by weight, 5-15% of tantalum carbide ceramic powder, 0.5-3% of nickel powder, 0.5-2% of titanium powder, 0.5-2% of molybdenum powder, 0.1-2% of poly (isobutyl vinyl ether), 0.1-2% of zinc stearate, and the balance 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 tantalum carbide ceramic powder, through addition of a trace amount of the nickel powder, a trace amount of the titanium powder and a trace amount of the molybdenum powder, refining of a two-phase micro-interface is promoted, and wear resistance and strength of a manufactured gear are further improved.
Description
Technical field
The present invention relates to a kind of field of powder metallurgy, be specifically related to a kind of high-strength wearable powder metallurgical gear
Material.
Background technology
Powder metallurgy be one metal dust (or mixture of metal dust and non-metal powder) as raw material,
Through shaping and sintering, manufacture metal material and the technology of all kinds goods.Powdered metal parts is raw
Production. art has Quick-forming ability and the advantage of material high usage of complex parts.
Sintered metal product has many types, including powder metallurgical gear.Existing powder metallurgical gear material is resistance to
Mill property is poor, intensity is low, to be improved.
