| In many industries, such as mining, mineral processing, chemical processing, and energy production, facilities and machinery are often subject to combined attacks of corrosion, impact and wear. The combined action of these processes, i.e., corrosive impact wear, often results in mutual enhancement, leading to a significant increase in total material loss.;In this study, research was conducted to investigate effects of strain rate of prior deformation on corrosive wear behavior of materials with focus on carbon steel. In order to understand the role of strain rate in corrosive impact wear processes, studies of (1) effects of prior deformation on the corrosion and corrosive wear of copper respectively with and without passivation involved; (2) effects of the loading speed on corrosion and corrosive wear of impact-fractured and slow bending-fractured surface layers of AISI 1045 steel; (3) effects of strain rate of prior deformation on corrosion and corrosive wear of AISI 1045 steel were conducted more systematically using electrochemical test and corrosive sliding wear tests, respectively. In order to understand the mechanism responsible for the strain rate - corrosive wear behavior relationship, SEM fractography, X-ray line profile analysis and micro-hardness testing were employed to investigate changes in microstructure and corresponding mechanical properties with respect to the strain rate. During the studies, a modified experimental tribo-corrosion technique was developed to quantitatively investigate the corrosion-wear synergy for the materials. |
