Author: Olakanmi, EO ; Sepako, M ; Morake, J ; Kutua, S ; Hoosain, Shaik E ; Pityana, Sisa L Date: Aug 2018 The engagement of additive manufacturing (AM) technology in developing intermetallic coatings involves additional heat treatment with a view to obtaining desirable microstructure and mechanical properties. This eventually increases the lead ... Read more
Experimental and numerical analyses of geometrical and microstructural features of Tribaloy T-800 composite coating deposited via laser cladding-assisted with pre-heat (LCAP) process

Author: Nyadongo, ST ; Olakanmi, EO ; Pityana, Sisa L Date: Sep 2021 Laser cladded (LC) tribaloy (T-800) coating has been used for surface modification of engineering components in high wear and elevated temperature service environments. However, the cracking phenomenon often observed in LC T-800 coating is ... Read more
Hybrid optimisation studies on the microstructural properties and wear resistance of maraging steel 1.2709 parts produced

Author: Maodzeka, DK ; Olakanmi, EO ; Mosalagae, M ; Hagedorn-Hansen, D ; Pityana, Sisa L Date: Aug 2022 Improper selection of laser powder bed fusion (LPBF) process parameters tends to result in poor quality parts which imposes limitations with respect to the mechanical performance due to process induced defects. To address this LPBF processing ... 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
