COATING INCREASING THE FRICTION COEFFICIENT AND PRODUCTION THEREOF BY MEANS OF ATMOSPHERIC PRESSURE PLASMA COATING

摘要

The present invention provides an advantageous method for producing a coating which increases the friction coefficient (3) on a surface (5) of a component (6), wherein the method comprises the following steps: a) activating hard particles (1) that are coated in part or entirely by an adhesive (2) in a non-thermal plasma (low-temperature plasma) under atmospheric pressure; and b) producing the layer (3) which increases the friction coefficient on the surface (5) of the component (6) by depositing the hard particles (1) activated by the non-thermal atmospheric pressure plasma and coated with the adhesive (2) on the surface (5) of the component (6). Said method is particularly more economic for components with complex forms or large dimensions than known methods. No matrix or intermediary layers are required for anchoring the hard particles. The hard particles engage directly in the contact surfaces.
