Abstract

The Ti-based metal matrix composite samples are novel, fabricated by using high voltage electric discharge and spark plasma sintering processes. They have potential usage in the aviation industry. A research that allowed measuring an electrical conductivity of Ti-based composites was performed. A collinear four-point probe method was chosen for measurement of electrical conductivity. Needle-like probes were used to contact the tested sample. Other aspects of the measurement setup are discussed and selected according to relevant literature. A simulation was performed using COMSOL software to validate the measurement method. Furthermore, a simulation performed for contact force of the probes was performed. A 3D model of the measurement tool was created and designed. The measurement setup was tested and validated by using a copper sample. electrical resistance of Ti-based composite samples was measured, and electrical conductivity was calculated. Furthermore, samples were measured at different temperatures and resistivity dependence to temperature was presented. Experimental results are compared to similar research results.
钛基复合材料电导率测定方法的发展
采用高压放电和火花等离子体烧结工艺制备了Ti基金属基复合材料样品。它们在航空工业中有潜在的用途。进行了一项允许测量Ti基复合材料的电导率的研究。选择共线四点探针法测量电导率。使用针状探针来接触测试样品。根据相关文献对测量设置的其他方面进行了讨论和选择。使用COMSOL软件进行仿真,以验证测量方法。此外,对探针的接触力进行了模拟。创建并设计了测量工具的三维模型。使用铜样品对测量装置进行了测试和验证。测量了Ti基复合材料样品的电阻,并计算了电导率。此外,在不同温度下对样品进行了测量,并给出了电阻率对温度的依赖性。将实验结果与类似的研究结果进行了比较。
