摘要
本文概述了无缝钢管穿孔机顶头的失效形式及高温氧化热处理工艺。介绍了对氧化表面的扫描电子能谱分析，X－光衍射分析及氧化表面的光电子能谱分析的研究工作。
The high temperature oxidation processes of the piercing plug are introduced and studied. The quallty of the scale is an important fadtor that influencec the service life of piercing plugs. The analysis deals with the element distrbution, the structure of the scale and the oxygen weight percent on the plug surface by EPAM, X - ray and ESCA. The growth mechanism and the factor of scale are also brought into discussion.
