| abstract |
The invention relates to a tool having at least one convex or pointed and at least one concave or planar formed region comprising a substrate and a boride layer electrochemically deposited thereon at least in part compartments, wherein the boride consists of one or more metals of IVb, Vb and Vlb Elements is formed, wherein the average boride layer thickness in the convex or pointed area x and the average boride layer thickness in the concave or planar formed area is y, with y / x> 1.3. Furthermore, a method for producing such layers is described. |
