Author:Tlotleng, Monnamme; Akinlabi, E; Shukla, M; Pityana, Sisa L; Mathebula, T; Chauke, LevyDate:Nov 2014A method of synthesising a biocompatible HAP coating is presented. In the current study, Nd:YAG laser was used to directly melt pre-place HAP powder beds on Ti-6Al-4V. The processing parameters used were 750 W laser power, 5 mm/s scanning ...Read more
Author:Nyadongo, ST; Pityana, Sisa L; Olakanmi, EODate:Jul 2021It is anticipated that laser cladding assisted with preheat (LCAP)-deposited Tribaloy (T-800) composite coatings enhances resistance to structural degradation upon exposure to elevated-temperature oxidation service environments. The oxidation ...Read more
Author:Osburn, LDate:Mar 2008This study was performed in order to understand what work has been completed regarding the application of reactive surfaces primarily for pollution abatement in urban areas. These surfaces could then be applied to South African infrastructure ...Read more

Author:Katumba, G; Makiwa, G; Olumekor, L; Forbes, ADate:Jan 2008It is possible to design an optical material, through control of the substrate and coatings, to absorb a large fraction of the solar spectrum and to emit very little radiation energy in the near and far infra-red wavelength range. This requires ...Read more
Author:Jayaramudu, J; Guduri, BR; Rajulu, AVDate:Apr 2009The newly identified natural fabric from the tree of Sterculia urens was coated with polymethyl methacrylate. The tensile properties of both the uncoated and polymethyl methacrylate coated fabrics were studied. The tensile parameters such as ...Read more
