Cross-sectional images of the coatings revealed dense structures with low porosities. The coating thicknesses were 65 mu m for WC-12Co and 118 pm for WC-25Co. XRD analysis showed that no fragile phases were formed in the coatings. SEM images and electro-chemical 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.13 p.application/pdfengcc-by-nc-nd (c) Elsevier Ltd, 2018http://creativecommons.org/licenses/by-nc-nd/3.0/esCorrosió i anticorrosiusRevestiments protectorsCorrosion and anti-corrosivesProtective coatingsinfo:eu-repo/semantics/article6828922020-05-21info:eu-repo/semantics/openAccess
