Abstract: In the present study, the erosive wear of boat propeller blades with tungsten carbide cobalt (WC-Co) coatings by high-velocity oxy-fuel (HVOF) under different erosive wear conditions were investigated and compared with the wear of uncoated one. The (WC-Co) coating was deposited on Al7034 T6 composite reinforced with (Al₂O₃) and (SiC) particle in different weight percentages. Micro hardness test was employed to determine the hardness of the composite substrate. Eroded surface of the substrate was examined through scanning electron microscope (SEM). Finite element modelling was used to analyse the fracture surface of the propeller blade. Impact analysis was used to determine the stresses induced and deformation evolution under various impact condition. It is shown that crack was initiated from the surface of the blade and finally damages the blade at velocity 500 m/s under cyclic loading. This damage causes the improper functioning of the propeller blade and induced aerodynamic forces to increase the vibrational amplitude of the rotor blade. Results show that (WC-Co) coated propeller blade predominant over the life of the uncoated blade.
