Problem points of alloy series coating target materials
Ti-al alloy series coating target material is usually used for functional film layer. When it is used as decoration, there are the following problems: 1. The film layer itself has high internal stress, so the adhesion of the film layer to the 3d curved surface workpiece is poor. Proportional adjustment of Ti and Al elements in the target material is difficult to be realized in the production of target material. This is expected to be realized in the equipment of cylindrical target by installing Ti and Al targets in the vacuum chamber and adjusting the sputtering power ratio, which greatly reduces the cost of target material.
