| Abstract: |
| Cathodic plasma electrodeposition is a surface treatment and material preparation technology that combines traditional electrolysis technology and plasma. Compared with the traditional surface treatment and material preparation technology, the advanced technology of cathodic plasma electrolytic deposition can not only reduce the energy consumption in the deposition process, and improve the speed of surface treatment and material preparation, but also promote the increase of the density of the deposited layer and increase the bonding force between the deposited layer and the substrate. As a result, this advanced surface treatment and material preparation technology have attracted extensive attention from researchers in China and in other countries. In this work, the basic mechanism and evolution process of cathodic plasma electrolytic deposition are comprehensively explained. It includes the evolution of the voltage-current curve in the deposition process, the formation process of the gas sheath composed of hydrogen and water vapor near the cathode, the evolution law of plasma formed in the deposition process in the electrolyte, and the deposition phenomenon of metal ions gathered near the cathode gas sheath under the energized condition. Based on the analysis of the basic mechanism of the deposition process, the unique advantages of the cathodic plasma electrolytic deposition compared with other surface treatment and material preparation technologies are described. In view of the complex affecting factors in the process of the cathodic plasma electrodeposition, the effect of electrical parameters and solution parameters on the process and results of the cathodic plasma electrodeposition is analyzed and discussed in detail, and the effect rule of these electrical parameters and part of the solution parameters on the process of cathodic plasma electrodeposition are explained. The electrical parameters mainly include the operating voltage and deposition time in the straight and pulse modes, and the unique duty cycle and pulse frequency in the pulse mode. The solution parameters include acid content, electrolyte type, electrolyte concentration, solvent type, and additives such as polyethylene glycol, glycerol, carbon nanotubes, metal particles, etc. Through the analysis and discussion of the above factors, it provides the possibility for researchers from all over the world to freely control the morphology, structure, organization, and properties of the sedimentary layer by changing the experimental conditions, and obtaining the expected results. On the basis of analyzing and summarizing the basic mechanism and affecting factors of the above deposition process, the research progress of cathode plasma electrolytic deposition technology in many fields is analyzed. These research areas include advanced ceramic coatings, metal coatings and composite coatings in the field of coating preparation, catalyst field of high performance and self-support catalyst synthesis, microsphere synthesis field of nano microsphere and hollow microsphere, and graphene functional material synthesis and nitriding and carburizing and other material surface treatment field applications. Finally, combined with the current research hotspots, the potential application and development direction of cathodic plasma electrolytic deposition technology in the field of coatings, as well as the research prospects in new fields such as catalysts and graphene are analyzed and summarized. |
