摘　　要：试验研究了ＥＰＳ，ＰＭＭＡ，ＥＰＳ－ＰＭＭＡ共聚物模样铸钢件表面增碳的规律。认为新开发的ＥＰＳ－ＰＭＭＡ共聚物材料兼收了ＥＰＳ，ＰＭＭＡ二者的优点。The steel casting surface carburizing was studied in several series of tests using EPS, PMMA, EPSPMMA pattern. The reuslts showed that newly developed EPSPMMA compound pattern material has combined the advantages of both EPS and PMMA, and is a good material to reduce surface recarburizing for steel casting in EPC.
