The invention relates to a coated substrate, preferably coated tool for use in manufacturing processes, such as machining processes or forming processes, comprising a coated surface, said coated surface formed by a substrate surface made of a first material ( 1 ) and a coating system, preferably an arc-PVD-deposited coating system, applied on said substrate surface, said coating system comprising an amorphous carbon film ( 100 ), wherein the amorphous carbon film ( 100 ) is a tetrahedral hydrogen-free amorphous carbon film in which the share of the sp 3 bond percentages of the C—C bonds exceeds that of the sp 2 bond percentages. The invention further relates to a method.

A method for producing coated substrates involving deposition of at least one coating layer on a surface of the substrate. The coating layer is synthesized in the interior of a vacuum coating chamber by using reactive PVD cathodic evaporation techniques. Nitrogen gas is introduced in the vacuum coating chamber to be used as reactive gas, and at least one arc evaporation source comprising a target material operated as cathode for evaporating the target material is used. The method involves a reactive deposition of aluminium titanium nitride as a result of a reaction between aluminium and titan from the target material with nitrogen from the nitrogen gas comprised in the coating chamber.

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 TM x B y Si q , 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 AlB 2 crystal structure.
