利用场发射扫描电镜表征了Zr-Co粉体的形貌特征和烧结后的陶瓷薄膜结构，热重分析了Zr-Co粉体烧结过程的失重和相转变吸放热过程，X射线衍射分析跟踪了不同温度段烧结体系的组成变化趋势，在此基础上对粉体烧结后陶瓷薄膜的防氧化效果进行了分析，结果表明：温度对粉体的颗粒形貌和晶相结构有较大的影响，高温烧结的粉体性质稳定，经过1200℃烧结后的陶瓷膜层具有很好的致密性，具有很好的防氧化效果。

The author analyzed total oxygen content, nitrogen content in steel made by typical process and the inclusion composition, change rule, morphology and distribution qualitatively and quantitatively by image analyzer, big sample electrolysis, SEM and energy spectrum analysis. The results showed that final inclusion form was small granule MnS, calcium aluminate, a small quantity of silicate and lumpy Al2O3. By intensifying deoxidation alloying process control in converter, argon blowing and slagging control and desulphuration and calcium reduction operation in refining course and overall-protection casting, the oxygen content was reduced by 20% above averagely, nitrogen content was reduced by about 10% and the inclusion content was reduced by 30%.
