| 英文摘要 | One of the key issues in clarifying the mechanism of critical flow velocity (CFV) for erosion-corrosion is whether the surface film is ruptured mechanically below the CFV. This paper aims to address such an issue for titanium by using ion-labelling and colour-labelling methods. The results show that the pre-labelled ion and colour cannot be detected on the titanium surface after impingement in liquid-solid two-phase fluid below the CFV, suggesting the surface film has been ruptured mechanically. Accordingly, the phenomenon of CFV is attributed to the competition between the depassivation process induced by solid particle impacting and the subsequent repassivation process. Furthermore, a critical criterion is proposed and the expressions of depassivation time and repassivation time are derived and discussed. |
