在650 ℃的水蒸气中对喷丸处理和未经喷丸处理的TP304H钢和Super304H钢的氧化行为进行了研究.使用GIXRD,SEM和EDX对氧化膜进行了分析.结果表明,喷丸使TP304H和Super304钢的抗氧化性能显著提高.TP304H钢经喷丸处理后提高抗氧化性能的效果优于Super304H钢.喷丸在奥氏体钢表面产生的超细晶粒和滑移带促进了Cr向表面扩散并形成富Cr的氧化物.喷丸诱发的马氏体对Cr的扩散及氧化行为也起着重要作用.对经内壁喷丸处理和未处理的TP304H钢制成的锅炉再热器管,在实际工况下服役7474 h后,经过内壁喷丸处理的TP304H钢管,内壁氧化膜的厚度只有未喷丸管子氧化膜厚度的约3％.实验室短期试验及实际应用均表明,传统钢材TP304H制成的锅炉管,内壁进行喷丸处理是提高抗水蒸气氧化性能的有效途径.
