Method for repairing component

A method for repairing a component, comprising:

• tracing a non-consumable electrode across a defect/damage on the component at a preselected distance from the component;
• feeding a first metal powder and a second metal powder into a discharging gap between the electrode and the component, wherein the first metal powder comprises a first metal or alloy with a Vickers hardness rating of about 70-200% of the Vickers hardness rating of the component and wherein the second metal powder comprises a second metal or alloy having lubricating/anti-corrosion properties;
• controlling feed rates of the first and second metal powders separately;
• micro-spark depositing the first metal powder to the component to form a first metal coating layer from the first metal powder;
• and
• tracing the electrode back over the first metal coating layer and micro-spark depositing the second metal powder over the first metal coating layer to form a second metal coating from the second metal powder overlying the first metal coating layer, the first and second metal coating layers defining a hybrid metal coating.
