Abstract
A coated article includes a coated surface which consists of a substrate and a coating system. The coating system has at least one protective layer consisting of one or more transition metal borides and one dopant element, wherein: 13 the protective layer having chemical element composition defined by the formula TMBSi, where TM is one or more of the transition metal elements Chromium and Hafnium; Si is Silicon present in the protective layer as the dopant element; B is Boron; x is the concentration in atomic percent of TM; y is the concentration in atomic percent of B; and q is the concentration in atomic percent of Si, where x+y+q=1, 0.15≤x≤0.33, 0.40≤y≤0.67, and 0.1≤q≤0.40, and—the atomic concentration ratio of boron to the transition metals in the protective layer is higher or equal to 2, i.e. y/x≥2, and—the protective layer exhibits an AlBcrystal structure.
