In this study, 5, 10 and 15 wt.% commercial purity Co-Mo powders are added to Cu powders using the powder metallurgy method. The prepared powder mixtures are shaped under a pressure of 600 MPa in a uniaxial hydraulic a press and then sintered at 1000 °C for 30 min. Scanning electron microscopy is applied for microstructural analysis. In the microstructure analysis, it is seen that as the reinforcement ratio increases, the grain sizes increase, and it is evenly distributed in Cu. A wear test is then carried out. As a result of this test, the weight loss, friction coefficient change and wear diameter change results of the composites are obtained. Abrasion loads are applied at 15, 20 and 25 N for 4000 m. The samples manufactured for the tensile test are subjected to certain loads on a Shimadzu tensile device. As a result of the abrasion and tensile tests, it was determined that the sample reinforced with 5 wt.% Co-Mo has the best mechanical properties.

粉末冶金法制备的铜基钴钼增强复合材料的组织和力学性能

在这项研究中,使用粉末冶金方法将5、10和15 wt%的商业纯度Co-Mo粉添加到Cu粉中。制备的粉末混合物在单轴液压机中在600 MPa的压力下成型,然后在1000°C下烧结30分钟。扫描电子显微镜用于微观结构分析。在显微组织分析中,可以看出,随着增强比例的增加,晶粒尺寸增加,并且均匀分布在Cu中。然后进行磨损测试。作为该测试的结果,获得了复合材料的重量损失,摩擦系数变化和磨损直径变化的结果。在15 N,20 N和25 N处施加4000 m的磨损负荷。为拉伸测试而制造的样品在Shimadzu拉伸装置上承受一定的载荷。
