| 摘 要： | 用EPS做模型，干砂造型在负压的状态下浇注ZG25，系统研究涂层厚度对气化模铸造碳钢件表面含碳量变化。结果表明，适当的涂层厚度，铸件表面含碳量不会变化，随着涂层厚度的增加，铸件表面脱碳区－增碳区－正常区。

| Abstract: | Effects of coating layer thickness on the surface C content in ZG25 carbon steel casting in EPC by using EPS pattern, dry sand mould, and vacuum pouring were studied systematically. The results showed that surface C content has no change with proper coating layer thickness while with increasing in the coating layer thickness casting surface will appear in following sequence: decarburized zone carburized zone normal zone moreover,with decrease in decarbured zone and increase in carburized zone graduately. |
