Bright Treatment Line
Available Services
- Oxynitriding treatment
Low polluting, eco-friendly technology that enables a part to receive nitriding treatment simply by adding ammonia gas and a small amount of oxygen (air) into the furnace. - Oxidized membrane treatment
Produces a thin oxidized membrane of Fe3O4 on the surface of the part, which enhances abrasion resistance and corrosion resistance. In addition to individual treatment, part qualities can also be further enhanced by combining this treatment with gas nitrocarburizing or oxynitriding treatments.
