- 摘要:
- 发动机铝合金缸体和铸铁缸套的结合性能直接影响热传导性，需要对铝材和缸套之间的间隙及结合强度
进行质量控制。 采用模拟分析软件 FLOW-3D 对不同的缸体压铸工艺方案进行了分析，选取最优工艺方案进行生产；抽
取工艺稳定的铸件，分析了铝合金本体和缸套（喷铝）喷铝层的结合情况和抗拉强度，并与目前主机厂常用的蘑菇头缸
套的结合性能进行了对标。 结果表明，缸套（喷铝）和铝缸体的结合间隙优于蘑菇头缸套，结合强度满足性能要求
标准。
The bonding performance of aluminum alloy cylinder block and cast iron cylinder liner has a direct impact on
the thermal conductivity, so it is necessary to control the quality of the gap between aluminum and cylinder liner and the
bonding strength. The simulation software Flow-3D was used to analyze different cylinder die-casting process schemes, and
the optimal process scheme was selected for production. The casting with stable process was extracted, and the bonding
and tensile strength of the aluminum alloy body and the cylinder liner (aluminum spray) aluminum spray layer were
analyzed. The results show that the bonding gap between the cylinder liner (sprayed aluminum) and the aluminum cylinder
block is better than that of the mushroom head cylinder liner, and the bonding strength meets the performance
requirements.
