Porous multi-element lubrication nickel-containing phosphor bronze antifriction material and preparation method thereof

The invention discloses a porous multi-element lubrication nickel-containing phosphor bronze antifriction material and a preparation method thereof. The porous multi-element lubrication nickel-containing phosphor bronze antifriction material comprises the following components in percentage by mass: 5%-10% of pure tin powder, 2.0%-8.0% of nickel-plated graphite powder, 2.0%-12.0% of nickel-plated molybdenum disulfide powder, 2%-6% of phosphor copper (Cu3P) powder, 0.4%-1.0% of zinc stearate and the balance of pure copper powder. Phosphorus bronze with nickel as a strengthening element is added into a matrix of the material, and graphite and molybdenum disulfide are adopted as multi-element self-lubricating components; the porous multi-element self-lubricating nickel-containing phosphor bronze antifriction material disclosed by the invention has excellent comprehensive mechanical property, frictional wear property and oxidation resistance, can ensure excellent friction property under the working condition of hi
