The invention discloses a self-lubricating anti-friction and wear-resistant alloy material and its preparation technology. The present invention adds copper powder with a mass percentage content of 20-25%, 16-20% ferrotungsten powder, 10-15% silicon powder, 8-12% high-carbon ferrochrome powder, 5-10% graphite, 5~10% copper-plated molybdenum disulfide, with iron powder as the balance, the preparation process is as follows: 1) Powder preparation; 2) Mixing and drying; 3) Compression molding; 4) Lofting and pumping; 5) Melting alloy; 6) alloy casting. The alloy prepared by the invention has small friction coefficient, good self-lubricating performance and wear resistance, and the alloy has good application prospects in the field of friction reduction and wear resistance, such as high-speed rolls. |
