A method for restoration of a metallic coating of a component, wherein the coating includes a consumed portion (3, 4), the method comprising the steps of: a. identifying the consumed portion (3, 4) as a function of location on the component, wherein the identification is performed by using one or several non-destructive techniques; b. removing essentially only the consumed portion (3, 4) as a function of the location as identified in step a., wherein removal is carried out using an electrolytic method comprising the steps of: b1. immersing the component in an electrically conductive liquid bath; b2. electrically contacting the component and a counter electrode, which are immersed in said bath; b3. applying a potential between the component and said counter electrode, such that the component functions as an anode and the counter electrode as a cathode; b4. controlling the potential between anode and cathode and measuring the current in order to monitor the coating removal or controlling the current between the anode and the cathode and measuring the voltage in order to monitor the coating removal; and b5. stopping the coating removal of step b4. based on the monitoring of the coating removal; wherein in step b. the geometry and the material of the counter electrode for electrolytic removal is configured and arranged to selectively remove metallic coating as a function of the location as identified in step a., c. applying new metallic coating in a manner at least compensating for the coating removed in step b.. a. identifying the consumed portion (3, 4) as a function of location on the component, wherein the identification is performed by using one or several non-destructive techniques; b. removing essentially only the consumed portion (3, 4) as a function of the location as identified in step a., wherein removal is carried out using an electrolytic method comprising the steps of: b1. immersing the component in an electrically conductive liquid bath; b2. electrically contacting the component and a counter electrode, which are immersed in said bath; b3. applying a potential between the component and said counter electrode, such that the component functions as an anode and the counter electrode as a cathode; b4. controlling the potential between anode and cathode and measuring the current in order to monitor the coating removal or controlling the current between the anode and the cathode and measuring the voltage in order to monitor the coating removal; and b5. stopping the coating removal of step b4. based on the monitoring of the coating removal; wherein in step b. the geometry and the material of the counter electrode for electrolytic removal is configured and arranged to selectively remove metallic coating as a function of the location as identified in step a., b1. immersing the component in an electrically conductive liquid bath; b2. electrically contacting the component and a counter electrode, which are immersed in said bath; b3. applying a potential between the component and said counter electrode, such that the component functions as an anode and the counter electrode as a cathode; b4. controlling the potential between anode and cathode and measuring the current in order to monitor the coating removal or controlling the current between the anode and the cathode and measuring the voltage in order to monitor the coating removal; and b5. stopping the coating removal of step b4. based on the monitoring of the coating removal; c. applying new metallic coating in a manner at least compensating for the coating removed in step b..
