Boriding

Boriding is a thermochemical process used in surface technology to improve the surface hardness and wear resistance of metallic workpieces. In this process, boron is diffused into the surface of the workpiece, creating a boride layer. This layer gives the workpiece improved mechanical properties, such as increased hardness, wear resistance and corrosion resistance.

The boriding process usually takes place at high temperatures, often above 800°C, to allow the boron to diffuse into the workpiece. There are various methods of introducing boron into the surface, including pack boronizing, gas boronizing and electrolytic boronizing. Each method has its own advantages and applications, depending on the specific requirements of the workpiece and the manufacturing process.

Boronizing is used in various industries, including the automotive, aerospace and tooling industries, to improve the life and performance of components, especially those subject to high stress and wear.
