Abstract: A hard coating comprising at least one hard layer with dedicated architectural design for attaining enhanced tribological performance (low abrasive and adhesive wear) at room and elevated temperatures in contact with Al-, Zn- and Fe-based or other counter bodies.

Abstract: A coated product having coating that includes a layer of hard material having a defined multi-ply layer structure, thereby significantly minimizing or preventing heat input into the coated substrate resulting from the effect of thermal hot spots.

Abstract: A coating method based on gas phase deposition by arc evaporation, with the steps: selecting a first target as a material source for the coating; providing a coating chamber with an arc evaporation source including the selected target; loading the chamber with substrates to be coated; pumping down the chamber to a process pressure suitable for the arc evaporation; and igniting and operating the arc such that material is evaporated from the first target and is then deposited on the substrates to be coated, optionally after reaction with a reactive gas admitted into the coating chamber. The first target includes at least one matrix component and one doping component such that the doping component has a melting point at least 500° C. lower than the matrix component, and a melted drop of the doping component on a solid surface of the matrix component assumes a contact angle of a least 90°.

Abstract: A coated body includes a body (1) with a body surface (3) and a coating system (20) deposited on at least a portion of the body surface (3). The coating system (20) includes at least one hard friction reducing coating deposited as an outermost layer (9) which exhibits droplets (10) at its surface. The outermost layer (9) includes molybdenum copper nitride and/or molybdenum nitride and copper nitride, and at least some of the droplets (10) consist mainly of copper. Preferably most of the largest droplets (10) consist mainly of copper.

Abstract: A hard material layer system with a multilayer structure, comprising alternating layers A and B, with A layers having the composition MeApAOnANmA in atomic percent and B layers having the composition MeBpBOnBNmB in atomic percent, where the thermal conductivity of the A layers is greater than the thermal conductivity of the B layers. MeA and MeB each comprise at least one metal of the group Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, and Al, pA indicates the atomic percentage of MeA and pB indicates the atomic percentage of MeB and the following is true: PA=PB, nA indicates the oxygen concentration in the A layers in atomic percent and nB indicates the oxygen concentration in the B layers in atomic percent and the following is true: nA<nB, and mA indicates the nitrogen concentration in the A layers in atomic percent and mB indicates the nitrogen concentration in the B layers in atomic percent and the following is true: pA/(nA+mA)=pB/(nB+mB).
