| 摘 要： | 本文探讨了20钢在铸铁浴中经不同温度及时间渗碳的渗层组织。结果表明，试样在1270℃的铸铁浴中保留30秒，距表面130－150μm处，其渗层组织为渗碳体＋珠光体＋铁素体；试样在1300℃的铸铁浴中保留30秒，距表面0－120μm处，其渗层组织为渗碳体＋珠光体，且在基体上形成棒条状的碳化物。

| Abstract: | The microstructure of carburized layer in 20 steel cast-iron molten bath carburized at different temperature and time was studied in the paper.The research results show that the microstructure of carburized layer which is at 130～150μm from the surface is cementite+pearlite+ferrite,when specimen immevsed for 30s in 1270℃；the micvostruchre of carburized layer which is at 0～120μm from the surface is cementite+pearlite,and bar carbides is obtained in the base. |
