顶头的高温氧化处理及其作用

HI-TEMPERATURE OXIDATION TREATMENT OF PIERCING PLUG AND ITS APPLICATION

阐述了穿孔顶头的高温氧化处理应包括预先氧化和穿孔过程中的氧化两个阶段；分析了最适宜的高温氧化气氛和氧化产物；指出了需进一步深入研究的领域。

The authors explain why the hi-temperature oxidation treatment process for piercing plug has to consist of two necessary stages, i. e.pre-oxidation and oxidation during piercing,analyze the optimum hi-temperature oxidation atmosphere, and at last predict the issues which need further research in this field.
