WC Cemented Carbides: Microstructural Aspects Comparing L-Pbf Additive Manufacture And Convencional Lps
Abstract
<jats:p>This work aims to compare the conventional powder metallurgy (PM), via Liquid Phase Sintering (LPS), with additive manufacture (AM), via L-PBF (Laser Powder Bed Fusion), considering WC cemented carbides and binders like Co, Ni and mixtures of Co and Ni. The mixtures were produced from dried slurries and some powder agglomeration was obtained with the use of organic binder. The great challenge was to improve flowability to obtain a bed as homogeneous as possible, so, additionally, a vibrating container was used to spread powder trying an uniform layer. Conventional samples were produced by press and high temperature vacuum sintering. For AM, laser power versus velocity were investigated. Microstructures were evaluated considering carbide distribution and the presence of cracks and porosities. The effects of different metallic binders were presented and discussed.</jats:p>
