@article { , title = {Comparative study of corrosion performance of HVOF-sprayed coatings produced using conventional and suspension WC-Co feedstock.}, abstract = {Corrosion properties of nanostructured coatings deposited by suspension high-velocity oxy-fuel (S-HVOF) via an aqueous suspension of milled WC-Co powder were compared with conventional HVOF-sprayed coatings. Microstructural evaluations of these coatings included x-ray diffraction and scanning electron microscopy equipped with an energy-dispersive x-ray spectroscopy. The corrosion performance of AISI440C stainless steel substrate and the coatings was evaluated in a 3.5 wt.\% NaCl aqueous solution at ~25 °C. The electrochemical properties of the samples were assessed experimentally, employing potentiodynamic polarization and electrochemical impedance spectroscopy. The potentiodynamic polarization results indicated that coatings produced by S-HVOF technique show lower corrosion resistance compared with the coatings produced by HVOF-JK (HVOF Jet Kote) and HVOF-JP (HVOF JP5000) techniques. Results are discussed in terms of corrosion mechanism, Bode and Nyquist plots, as well as equivalent circuit models of the coating–substrate system.}, doi = {10.1007/s11666-018-0775-2}, eissn = {1544-1016}, issn = {1059-9630}, issue = {8}, journal = {Journal of thermal spray technology}, note = {COMPLETED -- Now fully published 18/12/2018 LM -- Info via Scopus alert, Open Access article ADDITIONAL INFORMATION: Faisal, Nadimul Haque -- Panel B}, pages = {1579-1593}, publicationstatus = {Published}, publisher = {Springer}, url = {http://hdl.handle.net/10059/3217}, volume = {27}, keyword = {Corrosion, HVOF, Nanostructured coatings, S-HVOF, Suspension spraying, WC-Co feedstock}, year = {2018}, author = {Ahmed, Rehan and Vourlias, G. and Algoburi, A. and Vogiatzis, C. and Chaliampalias, D. and Skolianos, S. and Berger, Lutz-Michael and Paul, Shiladitya and Faisal, Nadimul Haque and Toma, Filofteia-Laura and Al-Anazi, Nayef M. and Goosen, Mattheus F.A.} }
