Three different WC-Co powder mixtures and a precipitation-hardenable steel powder, which is ordinarily used for this process, were compared. Metallographic analysis by means of optical and scanning electron microscopes was performed for evaluating their properties. Phase composition of the powders was studied using X-ray analysis. Results of these analyses enable the WC-Co powder mixtures to be ranked in the order of suitability for the SLM process.
