Provided herein is a method for securely fixing a connecting element on a metal workpiece by welding involving the formation of locally confined weld points that permits the friction-increasing, play-free, reversible connection of joined workpieces for applications in assembly and transportation. The connecting element includes a metal foil having hard material particles fixed on the joining surfaces by a metallic binding layer. Similarly, a component having a metal workpiece and the connecting element, which is suitable for the connection of workpieces to be joined in machine, plant, and motor vehicle construction, is also provided.

The invention relates to a suspension for producing a friction-increasing layer on a substrate, which comprises a liquid suspension medium, a predominantly inorganic binder or precursor compounds thereof and suspended hard material particles. The invention further relates to a shaped body comprising a substrate and a friction-increasing layer which has been applied to at least part of the surface of the substrate and comprises a predominantly inorganic binder matrix and hard material particles embedded therein, where the thickness of the binder matrix is less than the average particle size of the hard material particles so that the hard material particles project from the binder matrix and where the friction-increasing layer has been formed from a suspension according to the invention. The invention likewise relates to a process for producing the abovementioned shaped bodies and also their use for producing press or clamp connections and also as securing element.

Described is a device and method for a securing element for screw connections as an interlayer, between the screw head and supporting material and/or between the nut and supporting material, the basic body of the element consisting of a metallic material, to the top side and underside of which hard material particles are fixed, wherein the hard material particles are fixed by means of a metallic binding phase, the thickness of the metallic binding phase being lower than the mean diameter of the hard material particles, so that the hard material particles project out of the metallic binding phase.
