The invention relates to a tool or a part that is subject to wear and tear. Said tool or part comprises a basic member and a single-layer or multilayer coating. At least one layer of the coating is composed of aluminum borate or contains fractions of aluminum borate phases. Tools or parts that are subject to wear and tear and are coated according to the invention are provided with significantly improved resistance to abrasion, great ductility and resistance to oxidation, as well as a low coefficient of friction in contact with the part that is subject to wear and tear, resulting in a significantly improved service life behavior. ® KIPO & WIPO 2007
