Abstract
The invention relates to a tool, especially a cutting insert for cutting metallic materials, consisting of a hard metal, cermet, ceramic or steel base body and at least one coating deposited thereon. This single coating or in the event that there are several layers, the outer layer or the layer below the outer layer, consists essentially of molybdenum sulphide. The invention also relates to a method for producing the molybdenum sulphide coating by chemical vapour deposition. According to the invention, the molybdenum sulphide coating contains a mixture of the sulphide phases MoS.sub.2 and Mo.sub.2 S.sub.3 with an essentially random orientation (isotropic orientation) of the phase crystals. The coating is applied by means of a chemical vapour deposition procedure.
