The Advanced Nitriding Process – Enhance Fatigue Strength and Save Money

Ion nitriding with plasma ions is an industrial surface hardening treatment for iron-based materials. It is technically the highest of all nitriding processes and has many advantages over traditional salt baths and gas nitriding. The nitrated plasma portion is usually ready for use immediately after treatment that does not require treatment, polishing, or other post-mortem post-nitride treatment. The process is environmentally friendly, saves energy and causes little or no disruption. Steel is the most common material treated with plasma nitriding. This process allows precise control of the nitrided microstructure, allowing nitriding with or without a composite layer (white layer). In addition to improved material performance, the life of your parts will increase, significantly improving deformation limits, fatigue resistance, abrasion resistance and corrosion protection.

With a wide range of process control and optimization options, plasma nitriding allows you to meet stringent requirements that gas or salt bath nitriding cannot. Nitriding body depth, surface hardness and composite layer thickness (white layer) can be optimally achieved to meet the requirements of your application.

The plasma ion process is performed in a vacuum vessel at low temperature 400–560 ° C, where a high-voltage electric charge forms the plasma, causing nitrogen ions to accelerate and metal to be pressed. When nitrogen ions bombard a part, they heat the metal, clean the surface and absorb nitrogen on the surface, and can be applied to any ferrous metal.

The typical applications of plasma nitriding are:

·         Molds and punches for metal forming

·         Gears

• ·         Crankshafts

• ·         Feed screws

• ·         Camshafts

• ·         Guides

• ·         Balloons

• ·         Plastic molds

• ·         Molds for casting of non - ferrous metals and alloys

• ·         Milling tools

• ·         Drilling tools

Due to the increased compressive strength on the surface of the parts, the fatigue strength is improved five to ten times from its typical "raw" life, depending on the material and the construction of the part. Thus the fatigue strength is improved without distortion compared to other surface treatment methods, thus saving customers money.
