Microhardness and wear behaviour of surface modified Ti6Al4V/Zr-TiC metal matrix composite for advanced material

Author: Popoola, API ; Ochonogor, OF ; Abdulwahab, M ; Pityana, Sisa L ; Meacock, C Date: Dec 2012 Surface modification of titanium alloy (Ti-6Al-4V) was made using a Rofin Sinar 4 kW Nd: YAG laser. A laser multi-track 50% overlapping process was employed to produce Zr and Zr-TiC metal matrix composite (MMC) coatings on Ti6Al4V substrate. ... Read more
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
Particle variations and effect on the microstructure and microhardness of Ti6al4V hybrid metal matrix system

Author: Akinlabi, ET ; Nyembwe, KD ; Pityana, Sisa L ; Shongwe, MB ; Ochonogor, OF Date: Jan 2017 Manufacture of hybrid Ti6Al4 V alloy systems for application specifically in hot parts of turbine engines has been a challenge in recent years. This is due to the need to increase efficiency and reduce combustion rate and emission. In this ... Read more
