    摘要： The invention relates to bodies, coated by a SiC hard material layer or by a layer system comprising at least one SiC hard material layer, and to a method for producing said type of coated bodies. The aim of the invention is to supply bodies with SiC layers that have a particle-free, non-porous structure, a high degree of hardness, low brittleness, high bond strength, good oxidation resistance and a high resistance to crack growth. According to the invention, the bodies are coated by a SiC layer or a multi-layer coating system comprising at least one SiC layer, wherein the SiC layer comprises nano-crystalline 3C-SiC comprising halogen or a mixed layer comprising nano-crystalline 3C-SiC comprising halogen and amorphous SiC or nano-crystalline 3C-SiC comprising halogen and amorphous carbon. The coating of said bodies is carried out in a thermal CVD process, wherein a gas mixture comprising H

    x N hard material coating in bodies coated with a hard material comprising a multi-layer coating system containing at least one Ti
    1-X Al
    X N hard material coating and a high degree of wear resistance. According to the invention, said bodies coated with a hard material comprising a multi-layer coating system containing at least one Ti
    1-X Al
    X N hard material coating are characterised by the following features: the coating system consists of a) a bonding coating applied to the body, consisting of TiN, Ti(C,N) or TiC; b) a phase gradient coating that is applied to the bonding coating; and c) the single or multi-phase Ti
    1-X Al
    X N hard material coating or coatings applied to the phase gradient coating. The phase gradient coating consists of a TiN/h-AIN phase mixture on the side facing the bonding coating and has an increasing phase fraction of fcc-TiAIN with an increasing coating thickness, (the fraction being > 50%), towards the Ti
    1-X Al
    X N hard material coating(s) and a corresponding simultaneous decrease in the phase fractions of TiN and h-AlN. The coating according to the invention can be used in particular for tools and components consisting of steel, hard metals, cermets and ceramics, such as for example drills, milling cutters and indexable cutting inserts.
