摘要
对Zr-3试样进行500～700℃下3h氧化,研究其氧化组织及磨损行为。结果表明:Zr-3在500～700℃氧化后表面形成的氧化物主要为单斜ZrO2,另外还有少量ZrO1.99;氧化后Zr-3表面硬度增加,随氧化温度升高,氧化层硬度增加;Zr-3磨损的主要原因是表面塑性变形和氧化,而氧化后Zr-3的磨损主要是由于氧化膜发生剥落及其产生的二次磨损。
The oxidation of Zr-3 sample was carried out at 500-700℃ for 3 h, and the formation of the scale and the abrasion behavior of the scale was studied. The results reveal that the phases appear on Zr-3 after oxidation at 500-700℃ is mainly monoclinic ZrO, and little ZrOL99. The surface hardness of Zr-3 increases after oxidation, the higher oxidation temperature, the higher surface hardness. The abrasion of Zr-3 results from the plastic deformation and oxidation in the surface, while the abrasion of Zr-3 after oxidation is due to the spalling of scale and the abrasion from the spalling debits.
