DURNI-COAT® is a process for the functional coating of ferrous and non-ferrous materials (Electroless Nickel).
The DURNI-COAT® process consists in electroless deposition without any external source of electricity. In this process the workpiece is immersed into an aqueous process solution with a specific content of nickel ions. During the process these ions are reduced into metallic nickel. The chemical reacting agents and formulators of the electrons required in this process are the hypophosphite ions in the solution. These agents are transformed, by oxidation in the course of the reaction, into orthophosphite. A nickel-phosphorus alloy layer forms on the workpiece's surface. This layer effectively protects the workpiece against wear and corrosion.

DURALLOY®

DURALLOY® is an extremely hard, crack-free, precise, very thin and ultrapure metallic chromium layer. A nodular structured surface can be deposited in the layer thickness range from 1.5 to 20 µm. Due to the low process temperature of under 70 °C no changes to the structure of the base material occur ...read more

TUFRAM®

Synergetic Coatings » TUFRAM® TUFRAM® is a collective name for a family of coatings in which an aluminum surface is converted in to aluminum oxide. During this process the aluminum crystals grow out to a porous layer that remains hygroscopic for a short time and therefore has optimum adhesive properties. ...read more

NEDOX®

In the NEDOX® process, a nickel-phosphor alloy is applied to the substrate surface under defined conditions. This layer contains numerous micro pores that are enlarged in patented mass processes. The surface is sealed by the controlled impregnation of polymer particles. At the end of the NEDOX® process, ...read more
