▎ 摘　　要

NOVELTY - Reutilized diamond crushing material and graphene composite doped modified nickel-based alloy material comprises diamond crushing powder, graphene and nickel-based material, where the nickel-based materials comprises nickel powder, boron iron powder and chromium powder. USE - Used as reutilized diamond crushing material and graphene composite doped modified nickel-based alloy material. ADVANTAGE - The nickel-based alloy material: utilizes graphene and crushed diamond powder to generating finely dispersed self-lubricating graphite/graphene self-lubricating phase, which greatly improves anti-friction performance; and utilizes nickel powder, boron-iron powder and chromium powder, which improves wear-resistant property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of reutilized diamond crushing material and graphene composite doped modified nickel-based alloy material. The method utilizes steel substrate, binding agent and protective gas.
