研究了0Cr18Ni9Ti不锈钢及其分别经过双辉等离子渗Zr、渗Zr+渗C、渗Zr+预氧化、渗Zr+渗C+预氧化不同工艺阶段处理后的试样在静态空气中的抗高温氧化性.在1150℃静态空气中氧化20 h后,经过渗Zr+渗C+预氧化、渗Zr+预氧化、渗Zr+渗C、渗Zr处理的氧化增重分别只有未处理基材的0.04、0.07、0.09、0.12,表明抗氧化性能较未处理的基材都有很大程度的提高,其中经过渗Zr+渗C+预氧化处理后,效果最佳,其次依次是经过渗Zr+预氧化、渗Zr+渗C、渗Zr处理的试样;高温氧化后,不锈钢基材表面氧化严重,氧化层多次剥落,截面上出现了非常宽的裂缝;渗Zr、渗Zr+渗C、渗Zr+预氧化处理、渗Zr+渗C+预氧化处理的试样高温氧化后,表面致密度及截面形貌依次渐好,说明经以上各阶段处理后,材料的抗高温氧化性依次有所提高.特别是经渗Zr+渗C+低温预氧化处理的试样在高温氧化后,截面无孔洞与裂纹,其结构非常致密,表面平整,基体与改性层有一条明显的界面且结合比较牢固.
