Abstract
A method and system is provided for reducing surface roughness of a diesel engine component. The method and system may apply a voltage to a plasma electrolyte polishing cell. The plasma electrolyte polishing cell may include a diesel engine component and an aqueous electrolyte solution. The method and system may cause a plasma layer to form around a surface of the diesel engine component as a result of applying the voltage to the plasma electrolyte polishing cell. The method and system may terminate the voltage to the plasma electrolyte polishing cell. The method and system may apply a coating process to the diesel engine component.
