example 1

[0038] Prepare each main raw material and auxiliary raw material according to the aforementioned proportion two, and the copper powder wherein can adopt general commercial copper powder; Then prepare electroless copper-coated graphite powder, electroless-plated Nickel-coated tungsten carbide powder; then according to step C, three kinds of copper powder, electroless copper-coated graphite powder, and electroless nickel-coated tungsten carbide powder are put into a V-shaped mixer and sealed, and mixed. The mixing time is 15 Hours, Cu80%-C15%-WC2.5%-Ni2.5% copper-based anti-friction composite powder can be obtained. After conventional pressing and sintering processes, copper-based anti-friction composite materials can be made. After testing, compared with the copper-based anti-friction composite material block material made of ordinary copper-based anti-friction composite powder, the friction-reducing performance of the copper-based anti-friction composite material made of the c...

Abstract

The invention discloses copper-based antifriction compound powder, which comprises copper powder, chemical copper plating coating graphite powder and chemical nickel plating coating tungsten carbide powder. The copper-based antifriction compound powder is made of main raw material and assisting raw material, the main raw material is copper and weight portion is 75 to 95 portion; assisting raw material comprises graphite, tungsten carbide and nickel and the weight portion of each component is as follows; 4 to 19 portion of graphite, 0.5 to 5 portion of tungsten carbide and 0.5 to 5 portion of nickel. The invention also provides a manufacturing method for copper-based antifriction compound powder which comprises: A. the step of preparing chemical copper plating coating graphite powder; B. the step of chemical nickel plating coating tungsten carbide powder; C. the step of mixing. The copper-based antifriction compound powder provided by the invention contains antifriction phase and strengthening phase and greatly improves performance and product service life of copper-based antifriction compound material made of copper-based antifriction compound powder; the manufacturing method provided by the invention has simple process and low cost and is suitable for conventional production.

Description

technical field [0001] The invention relates to an antifriction composite powder and a preparation method thereof, in particular to a copper-based antifriction composite powder and a preparation method thereof. Background technique [0002] Copper-based anti-friction composite materials are widely used in the production of high-speed self-lubricating oil-impregnated bearings, gears and sliding parts, as well as brushes and electrical contacts due to their unique electrical and thermal conductivity and wear resistance, low friction coefficient and high mechanical strength. It is an important material for components, and has a wide market demand in aerospace, machinery, automobile, electrical appliances and other industries. [0003] The existing common copper-based antifriction composite powder materials do not contain antifriction phases and strengthening phases at the same time, so that the antifriction properties, high temperature strength and wear resistance of the produc...
