为满足新的使用条件和要求,在金属—氟塑料自润滑复合材料 JFS—1基础上,将钢基换为 Cu 基,并增加多孔层厚度,研制成自润滑复合材料 JFS—2。制备工艺是:在10mm厚的铸造铝青铜 ZQAl 9—4板上,烧结一层特制 Cu 粉,并在多孔 Cu 层中灌入高温润滑剂~([1])。JFS—2材料的机加工性能良好,复合层间有较好的结合。这些都为扩大 In order to meet the new operating conditions and requirements, based on the metal-fluorine plastic self-lubricating composite material JFS-1, based on the replacement of steel-based Cu-based and increase the thickness of the porous layer, developed into a self-lubricating composite material JFS-2. The preparation process is as follows: a special Cu powder is sintered on a 10mm-thick cast aluminum bronze ZQAl 9-4 plate, and a high-temperature lubricant ~ ([1]) is poured into the porous Cu layer. JFS-2 material machinability is good, there is a better combination of composite layers. These are all expanded
