Abstract: In a process for carbonitriding metallic components (1), provision is made of at least one carburization phase (C1, C2), in which the metallic component (1) is carburized with a carbon-donating gas. In addition, provision is made of a nitriding phase (C1, C2, C3), which is assigned to the carburization phase (D1, D2) and precedes the carburization phase (D1, D2). Here, in the nitriding phase, the metallic component (1) is nitrided by means of a nitrogen-donating gas at least superficially at at least one surface region (4) of the metallic component (1). It is thereby possible to avoid an excessive concentration of carbon, and therefore component failure is prevented and it is possible to dispense with costly remachining steps, e.g. grinding.

Abstract: The present invention comprises the nitridization of stainless steel with a gaseous nitrogen compound such as nitrogen gas (N2), or ammonia (NH3) at high temperature wherein the reaction pressure is lowered. A base powder with properties similar to those of a martensitic stainless steel is prepared from a molten metal with the subsequent incorporation of selective additives such as cobalt, chromium, boron, copper, vanadium, niobium and mixtures thereof to improve high temperature resistance to scuffing and adhesive wear. The molten mixture is then atomized by water- or air-atomization to yield a base powder which is mixed with nitrogen or ammonia gas at various pressures in a static or fluidized bed to provide a nitrogen alloyed particulate, i.e., a nitrided particulate alloy. The powder is heated in a hot isostatic press under vacuum with argon gas at reduced pressure and later cooled to ambient (room) temperature. A second embodiment of the invention also comprises the use of a wrought iron-based stainless steel or casting as the starting material to be nitrided.

Abstract: A furnace of heat treatment capable of keeping a stable nitriding quality for a long period of time is provided. The furnace of heat treatment performs a halogenation treatment and a nitriding treatment by heating a steel material under a predetermined atmosphere. An alloy containing Ni ranging between 50 mass % or more and 80 mass % or less and Fe ranging between 0 mass % or more and 20 mass % or less is used as a material of surfaces of core internals exposed to a treatment space where the nitriding treatment is performed. Accordingly, a nitriding reaction is hardly caused on the surfaces of the core internals, and the halogenation treatment and the nitriding treatment to an article to be treated can be stably executed for a long period of time. Further, a nitrided layer can be stably formed according to purposes on any types of steel materials including a steel type hard to be nitride.
