Applied FilmApplied in surface treatment of magnesium alloys. This article will introduce the basic principles of magnetron sputtering technology and its application in surface treatment of magnesium alloys. At the same time, we will also look forward to the future trends of magnetron sputtering technology in the field of magnesium alloy surface treatment.
Characteristics and Applications of Magnesium: As an alkaline earth metal element of Group IIA on the periodic table, magnesium has a silver white luster and slight ductility. It has a low density, but a high tendency towards ionization. Therefore, a very thin oxide film will be generated in the air, making it difficult for the air to react with magnesium. Magnesium reacts with alcohols, acids, and hot water to produce hydrogen gas. In addition, magnesium emits strong white light when burned in air and can react strongly with halogens and sulfur. The main uses of magnesium include manufacturing aluminum alloys, die-casting, and desulfurization treatment in steel production.
Advantages of Magnetron Sputtering Technology: Magnetron sputtering technology is a commonly used method for surface treatment, which can form a film layer on the surface of magnesium alloys. These film layers have excellent anti-corrosion performance and strong wear resistance. Moreover, due to the lighter weight of magnesium compared to aluminum, magnesium aluminum alloys containing magnesium have excellent mechanical properties and are widely used in aviation, aerospace and other fields.
Application of Magnetron Sputtering Technology in Magnesium Alloy Surface Treatment: Magnetron sputtering technology has a good development trend in magnesium alloy surface treatment. It can prepare alloy surface facial mask with excellent corrosion resistance and strong wear resistance. In addition, magnetron sputtering technology can also be used to improve the hardness and wear resistance of magnesium alloys. The composition and microstructure of the surface facial mask can be controlled by adjusting the magnetic field and sputtering parameters, thus improving the performance of magnesium alloys.
Simplified calculation method for the "Bern" model: In order to better understand the process of magnetron sputtering, researchers have proposed the "Bern" model. This model can be used to calculate the temperature, particle velocity, and energy distribution of sputtering targets and deposited thin films. By simplifying the calculation method, the performance of the thin film can be predicted more accurately and the parameters of the magnetron sputtering process can be optimized.
The future trend of magnetron sputtering technology: With the continuous development of technology, magnetron sputtering technology will continue to make progress in the field of magnesium alloy surface treatment. In the future, magnetron sputtering technology will pay more attention to the composite performance and controllability of thin film layers. At the same time, new materials and processes will be explored to meet the demand for magnesium alloys in different fields.
