Résumé :

An alternative approach of graphene implementation inside a porous structure has been presented. It consists ofthree stages: (I) preparation of a graphene ink–binder combination; (II) incorporation of graphene inside aporous medium; and (III) co-sintering of graphene within pores. The technique was verified for nickel andstainless steel 316 L materials. The presence of graphene was confirmed by Raman spectroscopy in both casesafter co-sintering. The alloy material showed improved performance that positively affected the overall flowdynamics. A significant increase in permeability, with a 60 % improvement over uncoated variants, was obtainedalong with a reduction in capillary pressure.
