Abstract
In this study, WC-Co/NiCrBSi and Cr3C2 powders were coated on surface of Al alloys (AA7075-T651, AA5083, AA2024-T4) by using HVOF (High Velocity Oxy Fuel) process. The coated samples were characterized by means of a scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX, XRD), hardness and bonding strength. These results showed that the maximum hardness and minimum surface roughness have been obtained at specimens coated with WC-Co. The bonding strengths of specimens used AA2024-T4 substrates were maximum. XRD study revealed that WC, W2C, C, Co, Cr3Ni2SiC, W5Si3, Cr7C3, Cr3C2, Cr, and Ni phases are present in the coatings.
