摘要:
该文针对发动机活塞的磨损特点,采用活塞环材料(合金球铁)作为对磨副,分别在高温、高负荷、高速度等条件下,将常用的活塞材料ZL109和镶圈材料(高镍奥氏体铸铁)与硅酸铝短纤维增强ZL109复合材料(Vf=4.5%)进行了磨损对比试验。结果表明,复合材料在上述条件下的耐磨性能都明显优于ZL109的,在高负荷条件下,其耐磨性已超过铸铁镶圈。
Abstract:
Aiming at the w ear characteris tics of pist on, cont ras t w ear tests were researched with three kinds of materials: common pist on mat erial ZL 109; inserted ring mat erial ( such as aust enitic nihard) and ZL 109 composit e reinforced with aluminosilicat e fiber at fiber content v f = 4. 5%. T he results show ed that , under conditions of elevated temperature, exces s load and high velocity respect ively, wearing against piston ring mat erial ( alloy nodular cast iron) , the w ear resistance of the composite was always superior t o that of the pist on mat erial ZL 109, and surpas sed the w earing qualit y of the inserted ring material under the condit ion of excess load .
