Post-oxidation is an additional step in surface treatment processes, particularly after plasma nitriding. Let s explore how it contributes to corrosion resistance: Purpose of Post-Oxidation: After nitriding, the material s surface is enriched with nitrogen, resulting in improved hardness and wear resistance. However, nitrided surfaces can still be susceptible to corrosion due to their high nitrogen content. Post-oxidation aims to enhance the material s corrosion resistance by forming a protective oxide layer on the surface. Process of Post-Oxidation: Oxidation Step: The component is exposed to an oxidizing atmosphere (usually air) at elevated temperatures. Formation of Oxide Layer: During oxidation, the surface reacts with oxygen, forming a thin oxide layer. Benefits:Increased Corrosion Resistance: The oxide layer acts as a barrier, protecting the underlying material from corrosive agents. Improved Surface Stability: The oxide layer stabilizes the surface, reducing reactivity with aggressive chemicals. Enhanced Appearance: Depending on the material, post-oxidation can also improve the surface color and appearance. Application: Post-oxidation is commonly used after plasma nitriding of low and medium alloyed materials. It complements the benefits of nitriding by providing an additional layer of defense against corrosion. In summary, post-oxidation is a valuable step to enhance the longevity and durability of nitrided components, especially when corrosion resistance is crucial.

Plasma nitriding (Ion nitriding) is a plasma supported thermochemical case hardening process used to increase wear resistance, surface hardness and fatigue by generation of a hard layer including compressive stresses. The advantages of gaseous nitriding processes can be surpassed by plasma nitriding. Particularly when applied to higher alloyed steels, plasma nitriding imparts a high surface hardness which promotes high resistance to wear, scuffing, galling and seizure. Fatigue strength is increased mainly by the development of surface compressive stresses. Plasma nitriding is a smart choice whenever parts are required to have both nitrided and soft areas. The possibility of generating a compound layer free diffusion layer is often used in plasma nitriding prior to PVD or CVD coating. Tailor made layers and hardness profiles can be achieved.Plasma nitriding/ion nitriding is a modern thermochemical treatment which is carried out in a mixture of nitrogen, hydrogen and an optional carbon spending gas. In this low pressure process, a voltage is applied between the batch and the furnace wall. A glow discharge with a high ionisation level (plasma) is generated around the parts. On the surface area that is directly charged by the ions, nitrogen-rich nitrides are formed and decompose, releasing active nitrogen into the surface. Due to this mechanism shielding is easily done by covering the concerning areas with a metal blanket.Plasma nitriding allows modification of the surface according to the desired properties. Tailor made layers and hardness profiles can be achieved by adapting the gas mixture: from a compound layer-free surface with low nitrogen contents up to 20 microns thick, to a compound layer with high nitrogen contents and an add-on of carbonic gas (plasma nitro-carburation). The wide applicable temperature range enables a multitude of applications, beyond the possibilities of gas or salt bath processes.

Service Description: Plasma Nitriding produces a micro structure which is considerably different from that produced by gas nitriding. The outermost layer is extremely thin, typically 2-10 microns. It is mono-phased and contains either A or B ionitrides. It is unaffected by alcoholic nitric acid etch and remains white - hence it is referred to as the white layer. The mechanical properties of the surface i.e. wear resistance, ductility and resistance to rolling friction are much improved by this thin and homogenous white layer. Beneath the white layer is the diffusion zone, the hardness and depth of which depends on the material being treated, the treatment temperatures and the treatment time. The treatment gas ions penetrate the component surface where they impact, thus through grain as well as grain boundary diffusion occurs, producing small and evenly distributed nitride precipitates within the nitrogen diffusion zone. As the nitrogen precipitates in this zone are smaller and more evenly dispersed than those produced by gas nitriding, the ductility and torsional properties are considerably improved. Benefits: Improves Wear Resistance, Improves fatigue strength, improves basic strength, reduces friction, and reduces galling Latest Technology Most modern surface hardening process using Nitrogen Cost effectiveness No need for grinding after Plasma Nitriding, Prolongs component life, Saves on Plant down time, facilitates the use of smaller section for a given applied load Quality Approved to ISO9001-2000 Low Treatment temperature No Distortion Retains base hardness Hardness Profile: Up to 1200 VPN / up to 0.6 mm Effective Masking: Plasma Nitride selected areas of component only High Repeatability: Accurate control of Plasma Nitriding treatment parameters.

Plasma Nitrocarburizing Services is also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding. The process works to achieve the same result as the salt bath and gaseous process, except the reactivity of the media is not due to the temperature but to the gas ionized state.In this technique intense electric fields are used to generate ionized molecules of the gas around the surface to diffuse the nitrogen and carbon into the workpiece. Such highly active gas with ionized molecules is called plasma, naming the technique. The gas used for plasma nitriding is usually pure nitrogen, since no spontaneous decomposition is needed (as is the case of gaseous ferritic nitrocarburizing with ammonia). Due to the relatively low temperature range (420 C (788 F) to 580 C (1,076 F)) generally applied during plasma-assisted ferritic nitrocarburizing and gentle cooling in the furnace, the distortion of workpieces can be minimized. Stainless steel workpieces can be processed at moderate temperatures (like 420 C (788 F)) without the formation of chromium nitride precipitates and hence maintaining their corrosion resistance properties. Uses: These processes are most commonly used on low-carbon, low-alloy steels, however they are also used on medium and high-carbon steels. Common applications include spindles, cams, gears, dies, hydraulic piston rods, and powdered metal components.

Plasma Ion Nitriding is a process for surface treatment of metal parts to make them resistant to wear and fatigue.Parts to be treated are placed in a vacuum chamber and a high DC voltage (typically around 1000 volts) is established between the parts and the chamber wall. As nitrogen gas is introduced into the chamber, a glow discharge plasma (ionized gas) builds up around the parts. The reactive nitrogen atoms thus bombard the surface, forming a thin layer of hard metal nitrides. Advantages of Plasma Nitriding are:- Glow discharge that envelopes the entire surface achieves a consistent hardness and case depth. This is specially noticeable on complex geometries where gas nitriding case depths can be non-uniform. Plasma nitriding (H2+N2) least affects the surface finish of the product. Salt bath and gas nitriding, which uses ammonia (NH3) and phosphate for activa- tion , will roughen a ground or polished surface. Higher surface hardness is achieved at lower processing temperatures (500 C). Thus distortion is almost zero and no changes in the properties at the core of the material

Controlled process ensures accurate results Suitable for alloy steel, stainless steel, maraging steel, cast iron and SG. Iron
