What is plasma nitriding? How does a nitride layer arise? What is plasma nitriding? How does a nitride layer arise? Plasma nitriding is a thermochemical diffusion process for surface layer hardening. In this process, a surface layer of a workpiece or component is enriched with nitrogen. [...]
How does a plasma nitriding plant work? How does a plasma nitriding plant work? During plasma nitriding, a plasma is generated between the components and the vessel wall. This plasma ensures that chemical processes which normally only take place at high temperatures take place at low temperatures [...]
What is the difference between plasma nitriding and plasma nitrocarburising? What is the difference between plasma nitriding and plasma nitrocarburising? The key difference between plasma nitriding and plasma nitrocarburising is the different treatment gases: In plasma nitriding, the surface layers are enriched with nitrogen; in plasma [...]
Which materials can be plasma nitrided and which hardness can be achieved in the process? Which materials can be plasma nitrided and which hardness can be achieved in the process? Nitridable materials are steels, high-alloy steels and titanium. You will find an overview of the typical [...]
How long does the plasma nitriding last? How long does the plasma nitriding last? The process time of the plasma nitriding is composed of different phases: heating up, surface activation, dwell time at nitriding temperature and the cooling time. The treatment time at nitriding temperature depends [...]
Is the corrosion resistance retained when treating stainless steels? Is the corrosion resistance retained when treating stainless steels? Stainless steels can also be plasma nitrided. With the technology from Eltro-Corr, we offer the possibility of the plasma nitriding of stainless steel while retaining the corrosion resistance. [...]
What level of warpage should I anticipate with plasma nitriding? What level of warpage should I anticipate with plasma nitriding? Thanks to low treatment temperatures, plasma nitriding is especially low-warpage. In most cases, no rework is necessary after plasma nitriding and you can install the components [...]
Can sintered parts be plasma nitrided? Can sintered parts be plasma nitrided? Sintered parts can be plasma nitrided! In an Eltropuls treatment, an oil-removal process first takes place in the plasma nitriding plant, in which the calibration oil is also removed from the pores near the [...]
Why would I partially nitride components? How can I mask during plasma nitriding? Why would I partially nitride components? How can I mask during plasma nitriding? Partial nitriding by masking opens up considerable opportunities to the engineer for composite structures, such as optimum weldability and compressibility. [...]
How do I test nitride layers? How do I test nitride layers? The testing of nitride layers is described in detail in the following standards: DIN50190-3: Hardness depth of heat-treated parts; determination of the effective depth of hardening after nitriding DIN EN-ISO 6507-1: Metallic materials – [...]
