Abstract

For steel nitriding, treatment time is a important factor. Gas and plasma nitriding are usual method to increase surface properties by nitriding. A close retort is used. Total time for treatment are higher because are necessary transition time for heating and cooling. Fluidized bed offer a short time for heating and cooling because furnace having an open retort. Work paper is based by nitriding experiments by experimental fluidized bed furnace. A gas mixture of ammonia and nitrogen was used. For samples were used HHS (Rp3) . Results were investigated micrographic, surface hardness test (HV5) and micro hardness (HV0,05).
