Microstructure characterization of laser-deposited titanium carbide and zirconium-based titanium metal matrix composites

Author: Ochonogor, OF ; Meacock, C ; Pityana, Sisa L ; Popoola, PAI ; Dutta Majumder, J Date: Sep 2012 Laser metal deposition (LMD) is an additive manufacturing technique whereby a stream of metal powder is consolidated by a focused laser beam on the surface of a substrate or engineering component. The interaction zone between the laser beam ... Read more
Nd: YAG laser treatment of aluminium-TiB2 coated: optimization of corrosion properties

Author: Popoola, PAI ; Pityana, Sisa L ; Fedotova, T ; Popoola, OM Date: Jun 2011 As the reports in the literature regarding corrosion performance of Al/TiB2 MMC are rather contradictory, the optimization of laser surface alloying parameters for these composite coatings seems to be necessary. The characterization of the ... Read more
NiTi intermetallic surface coatings by laser metal deposition for improving wear properties of Ti-6Al-4V substrates

Author: Mokgalaka, MN ; Pityana, Sisa L ; Popoola, PAI ; Mathebula, T Date: Mar 2014 The NiTi intermetallic possesses a number of good properties, such as high wear, oxidation, and corrosion resistance. This paper focuses on the deposition of NiTi intermetallic coatings on Ti6Al4V substrate by laser melting of Ti and Ni ... Read more
