为了满足航空航天、能源、医疗等领域对高耐磨钴基材料的需求，本研究试图通过添加增强相和调整烧结温度来提高该材料的综合性能。结果表明，纯Co-Cr-W合金由γ-Co、M29C和M6C(Ni3W3C)组成，Co-Cr-W基复合材料由γ-Co、M29C、M6C(Co2W4C)、M23C6和WC组成。随着热压烧结温度的升高，元素在材料中的扩散变得充分，Co-Cr-W合金及其复合材料的组织更加致密。当烧结温度高于1150℃时，Co-Cr-W基复合材料的抗弯强度和韧性均高于纯Co-Cr-W合金。增强相的加入有利于复合材料获得多尺度的强化效果，使复合材料具有更全面的性能。我们的结果强调了添加增强相的重要性，并有助于优化制备Co-Cr-W合金的工艺。
In order to meet the demand for high wear-resistant Co-based material used in fields such.as aerospace, energy, medical, etc., this study attempts to improve the comprehensive performance.of this material by adding some reinforced phases and adjusting the sintering temperature. Results.indicate the pure Co–Cr–W alloy is composed of γ-Co, M29C, and M6C (Ni3W3C), and the Co–Cr–W.matrix composites are composed of γ-Co, M29C, M6C (Co2W4C), M23C6, and WC. With increasing the.hot-pressing sintering temperature, the element diffusion in the material becomes sufficient, and.the microstructure of Co–Cr–W alloy and composites materials becomes denser. When the sintering.temperature is over 1150 °C, the bending strength and the toughness of the Co–Cr–W matrix composites are higher than that of the pure Co–Cr–W alloys. The added reinforced phases help the.composites to gain a multi-scale strengthening effect, which makes the composites have a more.comprehensive performance. Our results emphasize the importance of added reinforced phases and.help to optimize the preparing process in preparing the Co–Cr–W alloys.
