|Abstract:||High velocity oxygen fuel (HVOF) sprayed cermet coatings are extensively used to combat erosion-corrosion in naval applications and in slurry environments. HVOF spray parameters such as oxygen flow rate, fuel flow rate, powder feed rate, carrier gas flow rate and spray distance have significant influence on coating characteristics like adhesion bond strength and shear strength. This paper presents the use of statistical techniques in particular response surface methodology (RSM), analysis of variance and regression analysis to develop empirical relationships to predict adhesion bond strength and lap shear bond strength of HVOF sprayed WC-CrC-Ni coatings. The developed empirical relationships can be effectively used to predict adhesion bond strength and lap shear bond strength of HVOF sprayed WC-CrC-Ni coatings at 95% confidence level|
