ABSTRACT:
A carrier material for a tool for treating surfaces is composed of a metal alloy with a homogeneous, fine-grained structure. The carrier material is treated in a material removing manner to obtain a predetermined size and a roughness. Then an activating layer, a pure metal layer and a transition layer composed for example from nitrogen are applied, so that the outermost region of the tool contains a non-metallic hard layer. The non-metallic hard layer has a high hardness and elasticity so that the tool is suitable especially for treating surfaces of structural parts.
