| Abstract: |
| Cathode plasma electrolytic deposition (CPED) technology is a new type of surface modification technology developed in recent years. It has the advantages of low cost, high efficiency, highly adjustable coating composition and structure, etc. Various types of coatings such as metals, alloys, ceramics, carbon films, etc. can be fabricated through electrolyte configuration and regulation. It has good application prospects in corrosion protection, high-temperature oxidation resistance, thermal barrier, catalyst carrier, structured superhydrophobic surfaces and biocompatible coatings, etc. The development process of CPED technology was introduced and some important events promoting its development were elaborated, including the proposal of cathodic electrical breakdown mechanism and the modification treatment method to achieve preparation of uniform and controllable large-area coating. Based on the different stages of the development of CPED technology, the research progress in the electrical breakdown and the deposition mechanisms of CPED technology were summarized, including the gas film layer breakdown theory and the gas-solid dual dielectric layer theory model proposed at different stages. Through comparison between the two theories, the development process of CPED technology was further elucidated. On this basis, a systematic summary was conducted on the modification and regulation methods of CPED process, including universal gas film layer modification and specific coating regulation modification. The characteristics of the two modification methods and their role in promoting the development of CPED technology were analyzed, and the problems and suggestions for improvement were pointed out. Based on different coating types, the research progress of coating deposition by CPED technology in recent years was reviewed, including the preparation of metal coatings, alloy coatings, alloy based composite coatings, ceramic coatings, modified ceramic coatings, and carbon materials with CPED technology. The structure and performance of metal and alloy base coatings as well as modified ceramic coatings were emphasized. The microstructure characteristics and specific application performance data of different types of coatings prepared by CPED were clearly displayed in the form of figures and charts, and the application potential of coatings prepared by different modification processes was further clarified. Analysis showed that specific regulation for specific applications played an important role in the future research of CPED technology. Finally, the research prospects, development directions, and unresolved issues of CPED technology were discussed, including its potential application fields, process and mechanism research, preparable coating systems, and the shortcomings of environmental friendliness, as well as corresponding improvement directions. It is believed that better electrolyte modification and gas film layer regulation technologies need to be developed to make the gas film layer thinner and more uniform, to achieve coatings with larger area and lower energy consumption. More systematic and comprehensive discharge mechanisms and models need to be proposed. Preparable coating systems should be expanded, and electrolytes should be optimized to achieve environmentally friendly preparation. At present, CPED technology is still in the stage of rapid development and has great potential for application. China is at a relatively advanced level in the development of this technology. More systematic, in-depth, and comprehensive research is needed to further expand its industrial application fields. |
