| description | The invention relates to a self-lubricating copper-based abrasion-resistant alloy which consists of the following elements in percentage by weight: 75-85wt% of Cu, 5-8wt% of Sn, 0.5-2wt% of lanthanum-cerium misch metal and the balance of lead; and an alloy material is prepared by weighing the raw materials according to the proportion, subsequently pre-smelting the alloy in a medium-frequency induction furnace, and carrying out atomization and deposition by using spraying forming equipment. According to the alloy material, on the basis of the conventional ZCuPb15Sn8 cast alloy, by adopting the novel preparation process with the addition of rare earth elements and spraying deposition, the strength and the self-lubrication of a matrix are improved, and the abrasion resistance is remarkably improved. |
