Abstract
Coated substrate comprising a surface coated with a coating comprising at least one coating layer of (TMAl)ONwith (0.75−y)≤z≤(1.2−y) and 0.6>y>0, exhibiting a solid solution with B1 cubic structure, wherein x is the content of aluminum in atomic fraction if only aluminum and TM are being considered for the determination of the element composition in atomic percentage, and y is the content of oxygen in atomic fraction if only 0 and N are being considered for the determination of the element composition in atomic percentage, wherein TM is one or more transition metals and 0.05<x<0.95, wherein y correspond to a value of oxygen concentration in the TMAlONcoating layer that produces an increment of the thermal stability in such a manner that no precipitation of w-AlN phase is produced when the coated substrate or at least the coated surface of the coated substrate is exposed to temperatures higher than 1100° C.
