Elaboration de multimatériaux multifonctionnels par métallurgie des poudres – Mécanismes de frittage de bimatériaux

Abstract : The processing of multifunctional multimaterials by powder metallurgy is useful to combine complementary properties and reduce the production cycle. A model Fe base/WC base bimaterial, with only three chemical elements, was studied to understand bimaterial sintering and develop a protocol to study the sintering of bimaterials. The protocol is based on physic-chemical approach, monomaterial sintering then bimaterial sintering. These results were applied to the sintering of X120Mn12 steel/carbide bimaterial with toughness and hardness properties. The same protocol was used to process the sintering of 1.4313 steel/Stellite 6 bimaterial, with mechanical and corrosion resistance properties. This work draws attention to the impact of chemical and mechanical interactions at the interface of a bimaterial during sintering.
