Cross-sectional images of the coatings revealed dense structures with low porosities. The coating thicknesses were 65 μm for WC-12Co and 118 μm for WC-25Co. XRD analysis showed that no fragile phases were formed in the coatings. SEM images and electrochemical results obtained after 700 h exposure to NaCl solution showed that WC-25Co exhibited better corrosion resistance performance. The WC-12Co and WC-25Co coatings withstood 1000 and 3000 h of salt fog spray test, respectively.engCold sprayEISMetal coatingsPolarizationSEMXRDArtigo10.1016/j.corsci.2018.03.010Acesso aberto2-s2.0-850440071682-s2.0-85044007168.pdf
