Author:Makoana, Nkutwane W; Yadroitsava, I; Möller, H; Yadroitsev, IDate:2018Global industrial adoption of laser-based powder bed fusion (LPBF) technology is still limited by the production speed, the size of the build envelope, and therefore the maximum part size that can be produced. The cost of LPBF can be driven ...Read more
Author:Bayode, A; Akinlabi, ET; Pityana, Sisa LDate:Jun 2016Laser metal deposition (LMD) is an innovative manufacturing technique that uses laser to melt powders to fabricate fully dense components layer by layer. It is capable of processing different metallic powders and can also be used for consolidating ...Read more
Author:Obadele, A; Olubambi, PA; Pityana, Sisa L; Popoola, APIDate:Jul 2011In order to examine the microstructure and hardness behaviour of WC cermets, coatings have been obtained by laser surface alloying technique. WC-9Co-4Cr particulate was injected onto the surface of AISI 304L austenitic stainless steel (ASS) ...Read more
Author:Hoosain, SE; Tshabalala, Lerato C; Skhosana, Besabakhe S; Freemantle, C; Mndebele, NDate:Nov 2021One of the main considerations in adopting the additive manufacturing (AM) technology is whether the material properties of the AM-produced part are comparable with the wrought material. This study compared the properties of AM-produced 304 ...Read more
Author:Seleka, TS; Pityana, Sisa LDate:Nov 2006Laser surface melting has been conducted on a 304 stainless steel (SS) with the aim of enhancing pitting corrosion resistance of the material. This process involves rapid melting of the material’s surface followed by rapid solidification to ...Read more
