)又称为微等离子体氧化(MPO) 、阳极火花沉积(ASD) Plasma micro-arc oxidation is also referred to as micro-arc oxidation ( MAO ), also known as micro-plasma oxidation (MPO) , anode spark deposition (ASD) ) ,还有人称之为等离子体增强电化学表面陶瓷化(PECC) 。 Or spark discharge anodizing (ANOF ) , also known as plasma enhanced electrochemical surface ceramics (PECC) . The basic principle and characteristics of this technology are: on the basis of ordinary anodization, arc discharge is used to enhance and activate the reactions occurring on the anode, so as to form high-quality workpiece surfaces with aluminum, titanium, magnesium metals and their alloys as materials. Method for strengthening ceramic membrane.

The method uses a special micro-arc oxidation power supply to apply high voltage to the workpiece, so that the metal on the workpiece surface interacts with the electrolyte solution, and a micro-arc discharge is formed on the workpiece surface. Under the action of high temperature, electric field and other factors, the metal surface is formed. The ceramic film achieves the purpose of strengthening the surface of the workpiece, greatly increasing the hardness, improving the wear resistance, corrosion resistance, pressure resistance, insulation and high temperature impact resistance. It is a new technology that directly grows the ceramic layer in situ on the surface of non-ferrous metals. This technology has been developed on the basis of anodization in the past ten years, but both have mechanisms, processes and film properties. Many differences. The so-called plasma is composed of a large number of free electrons and ions, and appears as an electrically neutral substance as a whole. It is called a fourth state other than solid, gaseous, and liquid. A substance in the thermal plasma state has strong electrical conductivity, concentrated energy, and high temperature, and is a high-heat, high-temperature energy source. Compared with the traditional anodic oxidation method, the micro-arc oxidation ceramic film is firmly combined with the substrate and has a dense structure. It has good abrasion resistance, corrosion resistance, high temperature impact resistance and electrical insulation, and has broad application prospects.
