Just a couple of thousandths of a millimetre make all the difference
BALINIT® coatings are just a few thousandths of a millimetre 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".
