A method for producing an Al—Cr—O-based coating on a workpiece surface, including: a) placing a workpiece in an interior of a vacuum chamber, and b) depositing a film comprising aluminum and chromium on the workpiece surface to be coated, wherein a ratio of aluminum to chromium in the film in atomic percentage has a first value corresponding to Al/Cr≤2.3, and c) forming volatile compounds of Cr—O, thereby causing at least part of the chromium contained in the film to leave the film in a form of Cr—O volatile compounds, and d) executing step c) during a period of time, within which the chromium content in the film is reduced until attaining a second value of the ratio of aluminum to chromium in the film in atomic percentage corresponding to Al/Cr≥3.5, thereby the film is transformed into a film containing a reduced content of chromium.
