The subject matter invention is a passivation process against the nitriding process in the parts where the hardness, toughness and fatigue strength are not desired to be changed after the nitriding process of any injector component (10). Accordingly said process is characterized by comprising the steps of: a. Subjecting the injector component (10) to a grinding process, b. Subjecting the injector component (10) to the chemical washing process, c. Subjecting the injector component (10) to the electrochemical washing process, d. Subjecting the injector component (10) to the nickel coating process. |
