Manganese is widely used in magnetron sputtering technology, mainly for
Coating materialAnd protective coating. Below, we will explore the application and importance of manganese in magnetron sputtering from multiple dimensions.
1. Improve corrosion resistance performance
Manganese, as an anodic coating, can significantly improve the corrosion resistance of metals after treatment. Manganese coating can prevent metal from corrosion in humid air and maintain its luster for a long time. This makes manganese an important protective coating material.
2. Suitable for magnetron sputtering equipment
Manganese is widely used in the preparation process of PVD coating materials. PVD technology is a method of physically evaporating or sputtering materials onto the surface of a substrate to form a thin film. Manganese can be used as a target material in various magnetron sputtering equipment such as single target systems, multi-target sputtering systems, and ion sputtering systems.
3. Physical properties
Manganese has a series of special physical properties, making it an ideal material for magnetron sputtering. The thermal conductivity of manganese is 7.81 W · m-1 · K-1, which means that manganese can effectively conduct heat and contribute to the uniform growth of thin films. The density of manganese is 7.21 g · cm ³, and the relatively high density makes the sputtered manganese film uniform and dense. In addition, the expansion coefficient of manganese is 21.7 μ m · m-1 · K-1, and the bulk modulus is 120 GPa, which also contribute to the stability and uniformity of the manganese coating.
4. Provide examples for argumentation
Taking LED backlight module as an example,
Magnetron sputtering coatingTechnology is widely applied in its manufacturing process. In LED backlight modules, it is necessary to use materials with good conductivity and corrosion resistance to prepare connecting wires and electrodes. Manganese, as a common material, plays a crucial role here. By using magnetron sputtering technology, manganese layers can be deposited on key areas of LED backlight modules to improve the conductivity and corrosion resistance of connecting wires and electrodes, thereby enhancing the performance and lifespan of the entire LED backlight module.
In summary, manganese, as an anodic coating material, is widely used in the manufacturing process of various equipment through magnetron sputtering technology. Its improved corrosion resistance, suitability for magnetron sputtering equipment, special physical properties, and specific applications in LED backlight modules make manganese an indispensable and important material in magnetron sputtering.
