Abstract
A wear-protective layer for cutting tools is formed by the chemical vapor deposition or chemical plasma deposition or plasma sputtering by depositing a plurality of layers to a support of the cutting tool to form a multilayer in which each successive layer remoter from the support has a higher elasticity module and a greater diamond portion than the preceding layer. The outermost layer is a layer of diamond.
