摘要: <正> 在石油催化裂化装置中,使用了钴基高温耐磨合金,它在700℃氧化环境下运行,因此研究其氧化特征是非常必要的。钴基合金的使用温度可达1000℃,Co-25％Cr合金具有较好的抗氧化性能,但对含有大量碳化物(Cr_7C_3)的钴基合金的氧化特征还研究得很少。

Abstract：The wear resistance of Co-26Cr-3Mo-2.5C alloy is shown to be related to the presence of precipitated particles. The long time oxidation dynamics at different temperatures was studied. Results indicate that there is a linear relationship at 700,800 and 900℃ either between weight gain in oxidation and time or detween the amount of the exfoliated oxides and time. When oxidized for 500 hours at 700℃, the oxides are mainly Co_3O_4 and Cr_2O_3 (also CoCr_2O_4 in minor amounts). Above 800℃, CoCr_2O_4 becomes the main oxide.
