Cobalt target with high intensity

The utility model discloses a cobalt target with high intensity. The cobalt target is manufactured by arranging a middle layer between a target material and a backboard and welding correspondingly, and a plurality of grooves are formed in a welding face between the target material and the backboard. Compared with the existing cobalt target, a contact area of the welding face is increased; the temperature and the pressure required in the welding process are reduced; and an obtained target material component is high in intensity and good in stability. According to the cobalt target with the high intensity, the pressure required by the welding can be reduced; the contact area between the target material and the middle layer and the contact area between the backboard and the middle layer are increased; stress generated between the target material and the backboard due to different linear expansion coefficients is effectively reduced; and the cobalt target with higher welding intensity can be obtained.
