nitriding furnace soft nitriding heat Treatment

- Jul 18, 2017 -

soft nitriding methods are divided into: gas soft nitriding, liquid soft nitriding and solid soft nitriding three major categories. At present, the most widely used in domestic production is gas soft nitriding. Gas soft nitriding is in the atmosphere containing active nitrogen, carbon atoms in the low-temperature nitrogen, carbon infiltration, common infiltration medium has urea, formamide, ammonia and triethanolamine, they occur at soft nitriding temperature decomposition reaction, producing reactive nitrogen, carbon atoms. Activated nitrogen and carbon atoms are absorbed by the surface of the workpiece and infiltrated into the surface of the workpiece through diffusion, thus obtaining nitrogen-dominated nitrogen-carbon infiltration layer.
