ABSTRACT:
There is disclosed a wearing part comprising a basic body, a coating applied directly to the basic body or to a backing provided on the basic body and which coating consists of one or a plurality of layers of oxycarbides and/or oxynitrides and/or oxyborides and/or oxyboron nitrides and/or oxyboron carbon nitrides of the elements Ti, Zr, Hf, B, Si and Al and having an oxygen content in a range of from about 0.1 to about 5% by weight, alternating in each case with one or a plurality of layers of aluminum-boron mixed oxides having a boron content in a range of from about 0.01 to about 1% by weight. Compared to previously known wearing parts provided with multi-layer coatings a wearing part in accordance with the present invention exhibits significantly increased resistance to wear, as well as excellent adhesive strength, with respect to the hard-material coating, thus resulting in a substantially prolonged useful life.
