The vacuum gas nitriding furnace is a cylindrical shell made of steel plates, and inside is a heating studio made of shaped standard refractory bricks. The heating chamber and the shell are filled with insulation materials. There is a stainless steel welded sealed furnace tank in the heating chamber. The upper part of the furnace tank is equipped with a vacuum rubber sealing ring, and the lower part is a water-cooled jacket. The top of the furnace cover is equipped with a soaking fan to ensure the uniform atmosphere in the furnace.
Vacuum Gas Nitriding Furnaces are specialized heat treatment systems designed to perform nitriding—a thermochemical surface hardening process—under controlled vacuum environments. This technology enhances the surface hardness, wear resistance, fatigue life, and corrosion resistance of metal components, particularly steel and certain alloys, by diffusing nitrogen into the metal surface to form hard nitrides. Compared to conventional nitriding methods, vacuum gas nitriding offers superior process control, improved surface quality, and environmental benefits, making it increasingly preferred in high-precision manufacturing sectors. The core of a vacuum gas nitriding furnace consists of a vacuum chamber equipped with heating elements, gas supply systems, vacuum pumps, and advanced process control units. During operation, the furnace evacuates air to create a high or low vacuum, eliminating atmospheric contaminants and enabling precise control over the process atmosphere. Nitrogen-rich gas—often ammonia (NH3) or nitrogen-hydrogen mixtures—is then introduced under carefully controlled pressure and temperature conditions, allowing nitrogen atoms to diffuse into the workpiece surface layer at temperatures typically ranging from 500°C to 600°C. Vacuum gas nitriding enhances surface properties by producing a hard, wear-resistant nitride layer, often combined with a diffusion zone beneath it that improves fatigue strength. This method reduces distortion and prevents surface oxidation or decarburization, which are common in open-air nitriding processes. The controlled vacuum environment also minimizes the formation of unwanted compounds and ensures a clean, uniform case depth with superior adhesion and dimensional stability. Industries such as automotive, aerospace, tooling, energy, and heavy machinery rely heavily on vacuum gas nitriding furnaces to treat components like gears, shafts, camshafts, crankshafts, valves, and dies. These components demand high surface hardness and fatigue resistance to withstand rigorous operational stresses and extend service life. Additionally, vacuum gas nitriding is suitable for treating stainless steels and other alloys that require precise surface hardening without compromising corrosion resistance.
