- Description
- The slurry erosion behavior of thermally sprayed Cr2O3 coatings on Aluminium alloy is evaluated in the current research. By employing a high-velocity oxy-fuel (HVOF) spraying process, Cr2O3 coatings were deposited on the Aluminium 6061 alloy. Microhardness, as well as microstructure of the coatings, were explored to analyze the developed coatings. Slurry erosive wear experiments have been conducted by varying the conditions of the slurry erosion process, such as test duration, slurry concentration, slurry speed, and size of impinging particles, on the erosion test rig. The outcome has shown that with an increase in slurry concentration, slurry speed, and impinging particle size, the slurry erosive wear loss increases. By utilizing 3D confocal microscopy and scanning electron microscopy, the wear mechanisms of uncoated and Cr2O3-coated samples have been examined. 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
