Abstract

The main aim of the present work is is to investigate the slurry erosion behavior of Al₂O₃-40TiO₂ and Al₂O₃-13TiO₂ ceramic coatings deposited using d-gun thermal spray process characteristics resulting in quality coating. Slurry erosion testing was performed using a pot-type slurry erosion tester to evaluate slurry erosion resistance of the coatings. Three parameters are considered for slurry erosion wear testing viz. Impingement angle, slurry concentration and type of coating used. Surface morphology was examined using SEM images. The erosion behavior and mechanism of material removal was studied and discussed based on microstructural examination. It was observed that Al₂O₃-13TiO₂ ceramic coatings deposited on SAE 431 exhibits higher slurry erosion resistance under all testing conditions as compared to Al₂O₃-40TiO₂ and uncoated substrate material.
