以 Cu、Sn、Ti 等为原料,利用热压烧结制备金属结合剂试样。研究 Ti 对 Cu 基金属结合剂性能的影响,并通过 Inspect S50扫描电子显微镜(SEM)对其微观结构进行分析。结果表明：随着 Ti 质量分数的增加,Cu 基金属结合剂试样的密度呈逐渐减小的变化趋势,抗折强度和冲击韧性呈先增大后减小的变化趋势,洛氏硬度(HRB)呈逐渐增大的变化趋势；与 Cu 基金属结合剂相比,当 Ti 质量分数为3%时,其抗折强度和冲击韧性最大,分别提高了5.27%和20.89%；同时,Ti 的加入,形成了新的核/壳结构；该结构由中心到边缘按照从 Ti 到 Cu-Sn 脆硬相进行的梯度过渡,其组织成分依次为 Ti/Ti-Cu/Ti-Cu-Sn/Cu-Sn。

Hot-pressing sintering technology was used to prepare metal bond with copper,silver, titanium.The effect of titanium on performance of Cu-based metal bond was studied with its micro-structure analyzed by Inspect S50 SEM.Results showed that along with increasing Ti,the density of Cu-based metal bond tended to minish,while the flexural strength and impact toughness first rose and then decreased and the HRB tended to increase.Compared with Cu-based metal bond,the flexural strength and impact toughness of Cu-based metal bond with 3wt% of titanium were maximum and respectively increased 5.27% and 20.89%.The corn/shell structure that from center to edge changed from Ti to hard and brittle phase of Cu-Sn gradienthy,namely Ti/Ti-Cu/Ti-Cu-Sn/Cu-Sn.
