利用离子探针分析仪分析了铸钢件的Ｃ、Ｈ浓度分布规律。实验结果表明，采用聚苯乙烯泡沫塑料模时，铸钢件表面不仅存在增碳现象，同时还发现有增氢的问题。铸件表面的增碳和增氢，既恶化了铸件的加工性能，也降低了材料的塑性和韧性。

Using the ion probe mass spectrometer

this paper presents the carbon and hydrogen content in the steel casting produced by Evaporative Pattern Casting（EPC）. Not only carbon pick up

but also hydrogen pick up were discovered on the surface of steel casting. When the mold was made up of polystyrene foam plastics

this defect worsens the machining properties and downs the palsticity and toughness.
