Hard metal coating
Also known as: Thermal hard metal coating, Hard metal roller coating
The hard metal coatings made of titanium, aluminum and chromium oxide are resistant against wear from sliding and rubbing abrasion. They also offer a wear protection for the guiding of films, fibers, paper and cardboard. Defined surface structures ensure the transport and the air exhaustion.
Good sliding properties are achieved through coatings which have been ground. Hydrophilic or hydrophobic properties can be attained depending on the respective processing stage.
The essential properties of PROTEK hard metal coatings:
