EURO PM2018 (Powder Metallurgy) Congress & Exhibition, 14-18 October 2018, Bilbao, Spainhttp://hdl.handle.net/10204/10681Paper presented during EURO PM2018 (Powder Metallurgy) Congress & Exhibition, 14-18 October 2018, Bilbao, SpainLaser Enabled Net Shaping technology in the manufacture of cemented tungsten carbides is challenging and many scientific gaps still need to be addressed to ensure commercial viability. In this study the feasibility of using LENS® to produce cemented tungsten carbides having a steel binder was investigated. A full factorial design of experiments (DoE) was used in order to configure the LENS® process parameters which were varied, namely, powder feed rate, traverse speed, and laser power. Single wall samples were deposited and characterized using scanning electron microscopy (SEM), electron dispersive x-ray spectrometry (EDS) and X-ray diffraction (XRD). Vickers micro-hardness, surface roughness measurements, and porosity of the samples were also done.enLaser enabled net shapingWC-Fe alloysConference PresentationMolobi, E., Sacks, N., & Theron, M.
