Burnishing creates a decorative brownish to black oxide layer, which acts as a weak protective layer on iron-containing surfaces to reduce corrosion. The non-permanent corrosion protection of a burnished steel part is optimized by treatment with oils.
- The burnished surfaces are very ductile, grip-resistant and temperature-resistant up to approx. 300 ° C, whereby they do not change color.
- Corrosion protection (improved by oiling)
- True to size
Areas of usage
For technical reasons, burnishing is mostly used in tool and mechanical engineering for temporary corrosion protection in order to increase the shelf life of workpieces. Due to the deep black surface, the browning is also suitable as a decorative coating.
