| Erosion-corrosion | |
| Erosion-corrosion by either solid particle or liquid impact remains an issue affecting a wide variety of industries (from coal conversion processes to steam turbines in nuclear power generation). The E-C phenomena depend on properties of the material tested, particle properties and the nature of the environment (impact velocity, temperature and corrosivity). In studies of erosion-corrosion, the effects of alloy corrosion resistance are generally not well understood. The aim of the present work was to undertake a systematic study on the effects of erodent velocity for a 12 Cr stainless steel (taking for comparison a mild steel). Experiments were carried out in a FB rig at temperatures from 300 to 6000C and impact velocities between 1.5 and 4.5 m/s. The erodent used was alumina particles. Here, weight change data and analytical scanning electron microscopy were used to characterize materials degradation. The results showed that the ranking order of the wear rates of the alloys varied as a function of temperature and velocity. Reasons to explain the behavior found are given and discussed. | |
