采用粉末轧制工艺将Al粉、Al-Pb粉及SAC粉等三种粉末制成Al-(Al-Pb)-SAC三层复合轴承合金板。粉末预先进行脱气处理并采用较大的轧制力进行粉末轧制,可避免烧结板的鼓泡并获得机械性能较好的烧结板。
Aluminum powder, Al-Pb powder and SAC powder were made into Al- (Al-Pb) -SAC three-layer composite bearing alloy plate by powder rolling process. The powder is degassed in advance and subjected to powder rolling with a large rolling force, so that bubbling of the sintering plate can be avoided and a sintered plate having good mechanical properties can be obtained.
