Bioceramic hydroxyapatite coating fabricated on TI-6Al-4V using Nd:YAG Laser

Author: Tlotleng, Monnamme ; Akinlabi, E ; Shukla, M ; Pityana, Sisa L ; Mathebula, T ; Chauke, Levy Date: Nov 2014 A 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
Isothermal oxidation performance of laser cladding assisted with preheat (LCAP) Tribaloy T-800 composite coatings deposited on EN8

Author: Nyadongo, ST ; Pityana, Sisa L ; Olakanmi, EO Date: Jul 2021 It 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
Literature review on the application of titanium dioxide reactive surfaces on urban infrastructure for depolluting and self-cleaning applications

Author: Osburn, L Date: Mar 2008 This 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
The proton conductivity and mechanical properties of Nafion®/ ZrP nanocomposite membrane

Author: Sigwadi, R ; Dhlamini, MS ; Mokrani, T ; Nemavhola, F ; Nonjola, Patrick NT ; Msomi, PF Date: Aug 2019 Zirconium phosphates (ZrP) were incorporated into Nafion® 117 membrane by impregnating method to obtain a reduced methanol permeation and improved proton conductivity for fuel cell application. The mechanical properties and water uptake of ... Read more
Solar selective absorber functionality of carbon nanoparticles embedded in SiO2, NiO and ZnO matrices

Author: Katumba, G ; Makiwa, G ; Olumekor, L ; Forbes, A Date: Jan 2008 It 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
Tensile properties of polymethyl methacrylate coated natural fabric Sterculia urens

Author: Jayaramudu, J ; Guduri, BR ; Rajulu, AV Date: Apr 2009 The 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
