摘要: 用声发射(Acoustic Emission)方法及扫描电镜SEM/EDXA,对Co-40Cr合金在1000℃空气中20h恒温氧化后表面膜的开裂和剥落进行了研究。并与该合金表面离子注入3×10 16Y+/cm2和3×10 17Y+/cm2 后的氧化结果进行了比较。结果表明,离子注钇后极大地改善了合金表面氧化膜的抗开裂和抗剥落性能。此外,用声发射方法能够间接地测量出氧化膜/合金界面处“预存缺陷”(pre-existing defects )的分布情况。离子注钇改善合金表面氧化膜的粘附性与注钇后减小了界面处:预存缺陷“的数目及平均大小有关。

Abstract:Acoustic emission (AE)and SEM/EDXS were used to study the cracking and spalling behavior of the scale formed on Co-40Cr aloy after 20h isothermal oxidation in air at 1000℃.By comparing the cracking and spalling behavior of scale formed on 3×10 16Y+/cm2 and 3×10 17Y+/cm2 implanted and non-implanted Co-40Cr alloys, it was found that yttruim implantation greatly improved the anti-cracking and anti-spalling properties of the scale.AE was used to study the distribution of pre-existing defects at the scale/ alloy interface.The improvement of adhesion of the scale formed on yttrium-implanted aloy was attributed to the decrease in the size and number of pre-existing defects at the scale/ alloy interface
Key wordsCo-40Cr alloy    acoustic emission    ion implantation    rare earth effect(REE)    conglutinate
