Magnetron sputtering technology can prepare thin film materials with high purity and adhesion, which are widely used in surface protection, decoration and other fields.

2. Vacuum evaporation technology: Vacuum evaporation technology involves heating and evaporating materials, and then condensing them onto a substrate to form a film. This technology has a high deposition rate and low temperature, making it suitable for preparing various metal and non-metal thin film materials. With the continuous progress of technology, the application of vacuum deposition technology in fields such as optics and electronics is gradually increasing.

3. Ion beam deposition (IBD): IBD technology achieves thin film deposition by injecting ion beams onto the substrate surface. Compared with traditional PVD technology, IBD technology has a higher deposition rate and more precise control of film thickness. IBD technology has broad application prospects in the preparation of special functional films, surface strengthening, and other fields.
