Abstract
Radio-frequency hollow cathode discharge has gained more interest due to the characteristics of micro-size plasma source. It has proven to be very effective to treat local surface of the component. A radio-frequency hollow cathode system has been developed in our group. The cathode may be made of stainless steel, titanium alloy or tantalum alloy. The cathode is shielded using a water cooled electrode. In this paper the system was utilized to treat the inner wall of cylindrical bore. The diameter of the cylindrical bore ranged from 30 mm to 100 mm. The implantation voltage changed from 5 kV to 30 kV. The stainless steel samples were utilized to evaluate the effectiveness of the processes. The experimental results have demonstrated that the process has substantially improved the wear resistance and corrosion-resistance using nitrogen plasmas. The implantation dynamics monitored by a ring-shaped detector has also been presented.
