Just a couple of thousandths of a millimetre make all the difference
BALINIT® coatings are just a few thousandths of a millimeter thick but harder than steel; these low-friction coatings are extremely wear-resistant and chemically inert.
The optimum coating is determined on the basis of both conditions of use and economic considerations. The material and properties of BALINIT® coatings can be selected to match the customer's specific requirements.
The typical coating thicknesses that can be reproduced in mass-production lie between 0.5 µm and 4 µm. Sharp edges, textured or mirror surface finishes and close production tolerances remain unaltered. Therefore no finishing work is required and the coating can be carried out as the final production step.

Reliable measuring methods, applied under standardised test conditions are essential to correctly evaluate and determine the properties of PVD and PACVD coatings.
The following table gives an overview of the most important properties of BALINIT® coatings and includes links to detailed information on the individual coatings. Further information and application results for tools can also be found in the "Oerlikon Balzers Coating Guide".
