Main features and advantages of PVD coating (ion coating) technology - compared with vacuum evaporation coating and vacuum sputtering coating, PVD ion coating has the following advantages:
A. The adhesion between the film layer and the workpiece surface is strong, making it more durable and wear-resistant
B. The diffraction performance of ions is good, and the workpiece with complex shape can be plated
C. Film deposition rate is fast and production efficiency is high
D. a wide variety of coating types
E. Stable performance and high safety of the membrane (approved by FDA and implantable).
