The effect of TiC coating in electrode tip surface on spheriform electrode degradation during resistance spot welding zinc coated steel was investigated by SEM, EDX and XRD. 利用SEM、EDX和XRD等方法分析了在点焊镀锌钢板时球形电极表面熔敷TiC涂层对电极失效的影响。
The results show that electrode degradation mechanism was basically caused by wear due to fracture of local welding between the electrode tip surface and zinc coated sheet steel happen at electrode surface and alloying between electrode and zinc on zinc coated steel during resistance spot welding zinc coated steel. 结果表明:点焊镀锌钢板时电极的失效机制主要是电极和镀锌板之间局部焊接的断裂发生在电极表面而导致的电极磨损以及电极和镀锌板表面的锌之间的合金化。
