Abstract (en)

[origin: US2002166357A1] The invention concerns a method for making alloy components characterised in that after casting the preform (2) and before transferring it into a forging matrix (5), said preform, still hot at the end of casting, is transferred and completely immersed in a vessel (3) for graphitization coating, then, on coming out of the vessel, the preform temperature enabling the water to be evaporated so that the preform is homogeneously coated with graphite.
