For fast and secure determination of the quality of a metal coating as well as of an electrolyte for depositing a metal, in particular for electrolytic deposition of nickel such as of semi-gloss nickel and bright nickel and for analytical control of the deposition electrolyte, a method of inspecting a metal coating is provided, which involves the following method steps: a) depositing the metal coating from a deposition electrolyte onto a working electrode; b) electrolytically dissolving the metal coating through anodic polarization of the working electrode with respect to a counter electrode, which is in electrolytic contact with the working electrode; c) recording an electrical dissolution potential at the working electrode over time, said potential occurring during a dissolution of the metal coating; and d) determining a time-averaged vale of the dissolution potential.
