PURPOSE:To improve the bondability between a normal temperature damper and inner and outer layer reinforcing rings by filling and solidifying a normal temperature damper material in a melted state between the rings of inner and outer layers to form the damper. CONSTITUTION:Inner and outer layer reinforcing rings 3b, 3c made of nickel- base alloy are formed in advance by ring forging or bending welding, and mechanically cut, and finished as required. After copper plating is pretreated on the cut and finished surface, the rings 3b, 3c are concentrically disposed, melting copper alloy 14 is filled therebetween, solidified, and the three layers of the damper, and the rings 3b, 3c are integrated. Eventually, the alloy is age-hardened and heat treated, thereby improving the strength of the damper made of the alloy. |
