中文摘要:
      通过化学热力学从理论上推导高温合金Inconel625切削用刀具材料在高温下可能发生的氧化反应,选用硬质合金(YG8)、涂层硬质合金和陶瓷三种刀具材料,利用高温加热炉对不同刀具材料进行抗氧化实验,并对高温氧化产物进行扫描电镜(SEM)和X射线衍射(XRD)分析。结果表明: 在高温氧化试验中,YG8和涂层硬质合金的刀具材料中的WC和Co部分被氧化成WO3、Co3O4,且随着温度的升高,氧化反应更加剧烈;而陶瓷刀具中只有TiC被氧化成了TiO2,表现出较好的抗氧化性能;三种刀具材料的抗氧化性的顺序为:陶瓷刀具>涂层硬质合金>YG8。
Study on the Antioxidant Properties of Tool Material Used for Cutting Inconel625

英文摘要:
      The oxidation reactions of different tool materials under high temperature were derived from the theory of Gibbs free energy function, and the experimental study on the high temperature oxidation of tool materials was carried out. Cemented carbide (YG8), coated cemented carbide and ceramic tool materials were used in this study, and the oxidation products under high temperature were analyzed by SEM and XRD. The results showed that the WC and Co were oxidized into WO3, Co3O4 respectively in the high temperature oxidation tests. With the increase of temperature, oxidation behavior is more severe. For the ceramic tool, onlyTiC is oxidized into TiO2, which showed very good antioxidant properties. The order of oxidation resistance of the three kinds of tool materials is as follows: Ceramic Cutting Tools > Coated Cemented Carbide > YG8.
