| dc.description.abstract | The erosion studies of plasma sprayed NiCrBSi / Mo / Flyash Cenosphere and NiCrBSi / Flyash Cenosphere on Superni 76 at room temperature for 30° and 90° impact angle were studied. The microstructure, adhesion properties, microhardness and porosity were investigated. Using SEM, EDS and EDAX techniques, the effect of phase change in the coating during the erosion was analyzed. The NiCrBSi/Mo/Cenosphere coating exhibits greater erosion resistance, and its loss of volume accounting nearly to 50% of the NiCrBSi / Cenosphere coating. Compared to a 90° impact angle, the smallest erosion loss was observed at 30°. The erosion process assessed using SEM micrographs showed that the coating suffered ductile fracture, exhibited acute deformation and had abnormal oxide cracks. The enhanced metal oxide has a shielding effect, can resist erosion, and thus has better erosion resistance. © Published under licence by IOP Publishing Ltd. | en_US |
