Corrosion and Abrasion Behaviors of T2 Sliding-collecting-current Material in Rainy Environment

The corrosion and abrasion behaviors of T2/QCr0.5 rubbing pairs in rainy environment were studied using a friction and wear tester of HST-100 under current-carrying condition. The morphology and macroscopic temperature of worn surfaces were observed and measured by scanning electron microscopy(SEM) and thermocouple respectively. The results show that the fog simutating rainy environment could improve the corrosion and abrasion behaviors of T2 sliding-collecting-current material by lowering temperature of worn surfaces. The corrosion and abrasion mechanism with fog was arc erosion and slight adhesive wear.
