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.
Claims11
A wear-protective layer for a support of a metallic or non-metallic hard material, said layer being formed by chemical vapor deposition or plasma deposition as a multilayer comprising a layer of diamond, and means for reducing a difference in elasticity between said support and said layer of diamond said means comprising plurality of layers arranged to be located between said support and said layer of diamond and formed so that each following layer remoter from said support has a greater diamond portion and a higher elasticity module than each preceding layer positioned below said remoter layer.
