Hard and Wear Resistant

Boronizing (boriding) is a thermo-chemical diffusion procedure in which hard and wear resistant boron layers are obtained by diffusing boron into the material’s surface. 

The use of the Borodur® procedure which we developed, enables us to obtain boron layers in a wide range of materials. This applies to almost every kind of steel, including corrosion resistant stainless steels, cast iron, nickel based alloys, cemented carbides and many other special metals..




In particular boride layers show the following advantages: 

1. High hardness of 1400-2400HV depending on the base material
2. High layer hardness also on unalloyed steels
3. Significantly improved adhesion compared to conventional hard material coatings
4. High resistance against abrasive wear
5. High resistance against adhesive wear
6. Good stability at high temperatures
7. Good resistance against meltings of Al and Zn 
8. Good behaviour with respect to acids 

The excellent adhesion of boron layers offers the possibility to harden the material after boronizing treatment, without spalling the existing layer. 



Borocoat® layers are applied within many industrial fields such as: 

Valve manufacturing, offshore technology and petroleum industry, textile industry, automotive industry, milling and disintegration technology.
