Multi-Step in Situ Preparation Tib2 Particle-Reinforced Copper Matrix Composites for Spot Welding Electrodes and Their Applications
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 2
Abstract
In order to improve the service life of spot welding electrodes, TiB2- reinforced copper matrix composites were prepared using a multi- step method. The physical phase and microscopic morphology of the TiB2-reinforced copper matrix composites prepared by the multi-step method were analyzed using X-ray diffraction (XRD), metallographic microscopy and scanning electron microscopy (SEM) characterization. By measuring the mechanical property indexes of the composites, it was found that the copper matrix composites prepared by the multi- step preparation had better comprehensive mechanical properties. The copper matrix composites prepared by the multi-step method were processed into spot welding electrodes, its life test results were the highest compared with other comparison samples, with a life time of 1 500 solder joints, which was 2.6 times longer than the life time of common chromium zirconium copper spot welding electrodes.
