钢背—青铜—聚四氟乙烯三层复合自润滑轴承材料(下称SF材料)具有优异的减摩耐磨自润滑特性,作为滑动轴承材料在机械设备中已获得广泛应用。由于氟塑料有熔融特性,金属基与氟塑料层的复合需经高温烧结处理,而高温烧结(?)工艺方法对SF材料的理化特性和摩擦磨损性能都有重大影响。 SF材料的烧结复合,目前国内普遍采用的仍是开式烧结法。这种
Steel back - bronze - PTFE three-layer composite self-lubricating bearing material (hereinafter referred to as SF material) has excellent anti-friction and anti-wear self-lubricating properties, as a sliding bearing materials in machinery and equipment has been widely used. Due to the melting characteristics of fluoroplastic, the composite of metal matrix and fluoroplastic layer needs to be sintered at high temperature, while the high-temperature sintering process has a significant effect on the physical and chemical properties and friction and wear properties of SF. SF sintered composite materials, the current widespread use of open-type sintering method is still. This
