| titleOfInvention | Iron-based bearing material with in-situ pore forming and lubrication enhancement functions and preparation method thereof |
| abstract | The invention discloses an iron-based bearing material with in-situ pore-forming and lubrication enhancement, which comprises the following components in percentage by mass: 80-88% of iron powder, 5-10% of copper powder, 0.4-0.8% of expanded graphite powder, 2-3% of nickel powder, 2-4% of ammonium molybdate powder, 2-4% of ammonium thiomolybdate powder and 0.5-1.2% of zinc stearate powder. Ammonium molybdate and ammonium thiomolybdate are preferably selected as composite pore-forming agents for the iron-based bearing material, and the pore-forming agents can react with a substrate material to synthesize solid lubricating components such as ferrous sulfide, copper sulfide, molybdenum disulfide and the like while decomposing and forming pores. Therefore, the iron-based bearing material has the oil lubrication function of pore oil storage separation and the solid lubrication function of a solid lubrication component in the friction process, and can ensure the excellent self-lubricating performance of the bearing material under the complex and severe lubrication working condition. |
