@inproceedings { , title = {Comparison of wear performance of thermal sprayed cermet (WC-Co) coatings from suspension and feedstock powders.}, abstract = {WC-Co coatings were deposited using conventional High Velocity Oxy-Fuel Jet-Kote (HVOF-JK) and Suspension HVOF (S-HVOF) methods. Microstructural and mechanical properties along with the wear resistance of coatings were investigated. Reciprocating sliding wear tests were conducted against sintered Si3N4 counter-body with a normal load of 25N and total sliding distance of 500m following ASTM G133-2 standard. Coatings were characterised by Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD) and nano-Indentation techniques. HVOF-JK coating showed good retention of WC whereas S-HVOF coating showed the presence of W, W2C and amorphous/nanocrystalline phases. Nano-indentation of HVOF-JK and S-HVOF showed that the relative hardness of the HVOF-JK coating was higher but their elastic modulus was lower. The lower total wear rate was exhibited by the HVOF-JK coating. This difference in wear performance is attributed to the difference in hardness of the coatings and decarburisation of WC particles.}, conference = {2017 International thermal spray conference and exposition (ITSC 2017)}, isbn = {9781510858220}, note = {COMPLETED -- Requested AAM from contact 2/8/2018 LM -- Chased 6/7/2018 LM -- Rec'd auto reply acknowledging email from info@messe-essen.de 8/6/2018 LM -- Requested permission from info@messe-essen.de and media@dvs-hg.de 8/6/2018 LM -- Info via Scopus 7/6/2018 LM ADDITIONAL INFORMATION: Faisal, Nadimul -- Panel B}, pages = {681-686}, publicationstatus = {Published}, publisher = {DVS Media}, url = {http://hdl.handle.net/10059/3043}, volume = {2}, keyword = {Nanocomposite, Sliding wear, Suspension spray, Tribology}, year = {2018}, author = {Ali, O. and Ahmed, R. and Alawadhi, H. and Shameer, M. and Faisal, N.H. and Al-Anazi, N.M. and Goosen, M.F.A.} }
