Design and optimisation of a pulsed CO2 laser for laser ultrasonic applications

Author: Forbes, A ; Botha, LR ; Du Preez, N ; Drake, TE Date: Jul 2006 Laser ultrasonic is currently the optimal method for non-destructive testing of composite materials in the aerospace industry. The process is based on a laser-generated, ultrasound wave which propagates inside the composite. The response at ... Read more
Effect of laser parameters on the properties of high entropy alloys: A preliminary study

Author: Dada, M ; Popoola, P ; Mathe, Ntombizodwa R ; Pityana, Sisa L ; Adeosun, S Date: May 2020 This preliminary study investigates the fabrication of Al-Co-Cr-Fe-Ni-Cu and Al-Ti-Cr-Fe-Co-Ni High Entropy Alloys with the Laser Deposition Technique. The effect of the laser parameters on the microstructure and hardness properties of the ... Read more
In-situ formation, anti-corrosion and hardness values of Ti-6Al-4V biomaterial with niobium via laser deposition

Author: Phume, L ; Popoola, API ; Aigbodion, VS ; Pityana, Sisa L Date: 2018 Ti-6Al-4V alloy biomaterials have low hardness, wear resistance, high corrosion rate and toxicity as results of release of aluminium and vanadium ions that led to the premature failure of the implant. In order to overcome some of these problem ... Read more
Investigating the elastic modulus and hardness properties of a high entropy alloy coating using nanoindentation

Author: Dada, M ; Popoola, P ; Mathe, Ntombizodwa R ; Adeosun, S ; Pityana, Sisa L Date: Sep 2021 Using a focused ion beam TTX-NHT3 Nanoindentation tester with a load of 500 mN, we study the micromechanical properties of laser-deposited AlCoCrFeNiCu high entropy alloy coatings. The indentation tests conducted were used to examine the ... Read more
Process optimization of high entropy alloys by laser additive manufacturing

Author: Dada, M ; Popoola, P ; Mathe, Ntombizodwa R ; Pityana, Sisa L ; Adeosun, S ; Aramide, O ; Lengopeng, Thabo Date: Aug 2020 Aerospace components and their coatings are required to possess excellent surface properties over a wide temperature range. Stainless steels, titanium, nickel superalloy, and more recently high entropy alloys (HEAs) have been used to improve ... Read more
