Plasma nitriding

Plasma nitriding is a surface treatment process that is used in metal processing to improve the surface properties of workpieces in a targeted manner. In this process, the workpiece, typically made of steel, is placed in a vacuum chamber and exposed to a nitrogen plasma.

By applying electrical energy, the gas is ionized and converted into a plasma-like state. The reactive nitrogen species in the plasma then diffuse into the surface of the workpiece. There they react with the metal atoms, form nitrogen compounds and thus create a nitrogen-enriched layer.

Plasma nitriding offers several advantages. Firstly, it increases the hardness, wear resistance and corrosion resistance of the treated surface. Secondly, it leads to improved adhesion of coatings and reduces the risk of cracking and deformation compared to conventional heat treatment processes.

In addition, plasma nitriding enables precise control of the nitriding depth and distribution, which makes it possible to adapt the treatment precisely to the requirements of different applications. The process is therefore used in a wide range of industries, including the automotive industry, tool manufacturing, aerospace and medical technology. Overall, plasma nitriding is an effective method for improving the surface properties of metal workpieces, helping to increase their performance and service life in demanding applications.
