Abstract
A method for repairing a component is provided. The method comprises: tracing an 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; controlling feed rates of the first and second metal powders separately; and electro-spark depositing the first and second metal powders to the component to form a hybrid metal coating. 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. The second metal powder comprises a second metal or alloy having lubricating/anti-corrosion properties.
