Influence of Ti and Cu on the corrosion properties of laser-deposited high entropy alloys

Author: Dada, M ; Popoola, P ; Mathe, Ntombizodwa R ; Pityana, Sisa L ; Adeosun, S ; Dlamini, Thembisile P ; Aramide, O Date: Nov 2021 In this study, AlCoCrFeNiCu (Cu-based) and AlCoCrFeNiTi (Ti-based) high entropy alloys were fabricated using laser additive manufacturing. The influence of the alloying elements and the laser processing parameters, the laser power and scanning ... Read more
Optimization of the corrosion property of a high entropy alloy using response surface methodology

Author: Dada, M ; Popoola, P ; Aramide, O ; Mathe, Ntombizodwa R ; Pityana, Sisa L Date: Jun 2020 Laser Additive Manufacturing was used to fabricate AlTiCrFeCoNi high entropy alloy and the corrosion properties of the alloy were investigated in 3.5 wt% NaCl solution. The tests were conducted via potentiodynamic polarization at room temperature ... 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
