摘要: 本文对比研究了用喷射法加入 CeO_2弥散质点的低碳钢(含 C0.20%wt)在空气中550～650℃恒温与循环氧化。结果表明:加入 CeO_2 弥散质点后降低了所有三个实验温度下的恒温与循环氧化速率。X-射线衍射分析表明:含 CeO_2弥散质点样品在600℃和650℃氧化后 FeO 层消失,在550℃氧化后 Fe_2O_3层增厚。氧化层/基体界面的金相观察表明:含 CeO_2样品形成“锯齿”状界面,因此改善了氧化层的粘附性和抗剥落能力。

Abstract：In this work,isothermal and cyclic oxidation of carbon steel(containing 0.20%wt C)with and without CeO_2 dispersion added by jet injection are investigated at 550°、600°and 650℃ in air.Test retsults show that the addition of CeO_2 dispersion reduces isothermal and cyclic oxidation rates at all three test temperatures. X-ray diffraction analysis of the scale shows that for steel containing CeO_2 dispersion,wustite(FeO) disappears after oxidation at 600℃ and 650℃, and hematite(Fe_2O_3) layer becomes thicker after oxidation at 550℃. Metallographic examination of the scale/substrate interface shows that specimens with CeO_2 dispersion posses“saw-tooth”intrface,which accounts for the better adhesion and spalling resistane of the scale.
