介绍一种用于发动机轴承的AlSn8Si2.5Pb2CuO.8Cr0.2新合金。专门开发的这种合金优化了抗咬合性,同时,又提供了极好的抗疲劳性和耐磨性。该合金的开发系利用高冷却率铸轧工艺的优点,并采用高温下把合金复于钢背上的粘结工艺。列出新合金的性能参数,包括抗疲劳、抗咬合特性及耐磨性,此数据包含与淬硬钢、球铁、软钢三种不同材料配对的抗咬合数据。 A new AlSn8Si2.5Pb2CuO.8Cr0.2 alloy for engine bearing is introduced. Specially developed alloy of this kind optimizes seizure resistance while offering excellent fatigue and wear resistance. The development of this alloy utilizes the advantages of a high cooling rate casting process and the bonding process of restoring the alloy to the steel back at high temperatures. Lists the performance parameters of the new alloy, including fatigue resistance, seizure resistance and wear resistance. This data includes the anti-seizure data paired with three different materials, hardened steel, ductile iron, and mild steel.
