Abstract: A coated tool, such as a rotating, cutting tool, includes a tool body and a multilayer wear protection coating system. The wear protection system coats a functional surface of the tool body that is subject to wear and includes a first undoped diamond layer and a second undoped diamond layer disposed over the first undoped diamond layer. The first undoped diamond layer is electrically conductive and exhibits grain boundary conductivity from delocalized electrons. The second undoped diamond layer is electrically insulating. The first undoped diamond layer is 4-20 microns thick and is made with diamond grains whose size ranges from 4-10 nm. The first and second diamond layers are applied by chemical vapor deposition (CVD) using a hot-wire method. The wear protection system also includes an additional undoped diamond layer that is electrically insulating and is disposed between the functional surface of the tool body and the first diamond layer.

Abstract: The present subject matter relates to a micromechanical component having a top face and a bottom face and at least two side faces, and a coating of diamond and/or diamond-like carbon (DLC) which encompasses all the surfaces of the component, wherein on at least one side face, across at least a part of said side face, the coating has a smaller coating thickness than that of the top face and/or bottom face, so that a reinforced area in reference to the at least one side face is produced.
