Abstract
The wearing part, such as a cutting insert, is made from hard metal or cermet. A hard-material coating is applied on the base material. The coating includes a single-layer or multilayer mixed-oxide coat, predominantly comprising Al O , in which defined proportions of titanium oxide and boron oxide are dissolved or homogeneously distributed extremely finely. The wearing part is distinguished by a high wear resistance, which improves the service life, and a fine-grained structure and uniformity of the coat and by a highly economic application of the coat.
