摘要：

Slurry erosion performance of detonation gun (D-gun) spray ceramic coatings (Al2O3 and Al2O3-13TiO(2)) on CF8M steel has been investigated. Slurry collected from an actual hydro power plant was used as the abrasive media in a high speed erosion test rig. Attempt has been made to study the effect of concentration (ppm), average particle size and rotational speed on the slurry erosion behaviour of these ceramic-coated steels under different experimental conditions. The analysis of eroded samples was done using SEM, XRD and stylus profilometry. The slurry erosion performance of the D-gun spray Al2O3-13TiO(2)-coated steel has been found to be superior to that of Al2O3-coated steel. Both the coatings showed brittle fracture mechanism of material removal during the slurry erosion exposure.
