WEAR-RESISTANT COATING OF CUTTING TOOL AND METHOD OF APPLYING SAME ABSTRACT A wear-resistant coating of a cutting tool has at least a single layer of an interstitial phase which comprises alloying components and a non- metallic one the content whereof falls within the boundaries of a region wherein a compound of this interstitial phase having an all-best thermodynamic stability is homogenous. One of the alloying com- ponents functions as a catalyst which facilitates the compound with an all-best thermodynamic stability to form. A method of applying the wear-resistant coating to a cutting tool provides for condensing matter by virtue of ion bombardment and consists in introducing the catalyst into a vacuum by evaporating the material of a cathode and depositing a layer of coating on the base material of the cutting tool at a temperature thereof which permits a catalytic reac- tion to take place owing whereto the content of the non-metallic component falls within the boundaries of a region wherein the compound with an all-best thermodynamic stability is homogenous.
