| 摘 要： | 铝合金铸件在铸造过程中形成的疏松、缩孔、气孔等缺陷,会影响零件的气密性和抗压性能.为了解决铝合金机体废品率高的问题,采用了局部加压浸渗技术.此外,还介绍了浸渗剂与整体真空加压浸渗工艺,通过50 h台架试验后,经过浸渗处理后的机体没有发生渗漏.

| Abstract: | Aimed at the problem of often forming the casting defects,such as dispersed shrinkage,shrinking holes and gas holes,in aluminum alloy castings,affecting the air-tightness and press resistance performance of the parts,local press impregnation technology was adopted,and penetrating agents and total vacuum pressure penetrating process were introduced.It was proved that the cylinder block by impregnation process was not leakage after 50 hours bench scale test. |
