PRODUCTION of a COATING INCREASING THE FRICTION COEFFICIENT BY MEANS OF ATMOSPHERIC PRESSURE PLASMA COATING

摘要

The present invention provides an advantageous method for producing a coating (3) increasing the coefficient of friction on a surface (5) of an element (6), wherein the method comprises the following steps: a) activating of hard particles (1) partially or completely covered by a bonding agent (2) in a non-thermal plasma (low-temperature plasma) at atmospheric pressure; and b) producing a layer (3) increasing the coefficient of friction on a surface (5) of the element (6) by depositing the hard particles (1), which are activated by the non-thermal atmospheric pressure plasma and which are coated with the bonding agent onto the surface (5) of the element (6). Specifically, for elements having a complicated shape or having a big size, this method is more efficient than known methods. No matrix or intermediate layers are necessary to fix the hard particles. The anchoring of the hard particles takes place directly in the joining surfaces themselves.
