ABSTRACT
Plasma was discovered by Sir William Crookes in 1879, but it was not until 1928 that it was officially named plasma by Owen Langmuir and Tonks. Afterward, scientists began to research its various physical characteristics and application. In 1950, Kellogg and other scholars began to publish articles on Electrolytic Plasma Processing (EPP) (H.H. Kellogg et al. 1950). The cleaning technology in EPT is mainly used to replace the existing pickling processes, which mostly use strong acid solutions. If the coating process is carried out subsequently, it can significantly increase the adhesion and can also significantly reduce the thickness of the coating. In 2002, E.I. Meletis and other scholars published a paper on steel sheet surface cleaning and EPP of metal coating (E.I. Meleti et al. 2002). In 2010, A. Yerokhin and other scholars also published a research discussion on the use of pulsed
1 INTRODUCTION
Regarding the materials that Electrolytic Plasma Technology (EPT) can handle, in addition to the known conventional metallic materials, some scholars are trying to test non-metallic material coating technology. Carbon steel processing is mainly coating and heat treatment. The direction of stainless steel research is mainly on improving corrosions such as boronizing treatment, nitriding, surface cleaning, and so on. Titanium is mainly used for carburizing nitriding treatment, coating, and anodizing coating; aluminum alloy is applied to the anodic process as a bulk, but a part of aluminum is also taken as a coating material. The main research direction has been used to explore the nature of the material. The appearance of plasma electrolysis technology will hopefully bring a favorable turn of the phenomenon. When the surface corrosion resistance of stainless steel is enhanced by plasma electrolysis technology and compared with that of titanium, the price advantage will be able to reverse the medical instruments market. As far as
current plasma to assist the electrolytic cleaning of AISI4340 steel and again mentioned the application of plasma electrolysis in cleaning and its advantages and disadvantages (A. Yerokhin et al. 2002).
