Abstract：In this paper,the double high pressure pre-ionization technique is used to clean the oil on the metal surface by changing the length of two discharge zones with argon plasma jet.From the cleaning effect,when the length of the discharge zone is 6 cm,there is a critical discharge frequency for cleaning,and once the discharge frequency exceeds the critical frequency,the cleaning effect will be greatly improved.When the length of discharge zone is 10 cm,there is no critical discharge frequency for cleaning,and the cleaning effect is continuously improved with the increase of discharge frequency.At the same discharge frequency,the cleaning effect of plasma jet with discharge zone length of 10 cm is better than that of plasma jet with discharge zone length of 6 cm.The electron excitation temperature of the argon plasma jet produced in two discharge zones is found to be similar to that of the cleaning effect,indicating that the electron collision mechanism reflected by the electron excitation temperature plays a crucial role in the plasma cleaning process.
