| titleOfInvention | Preparation method of copper-aluminum gradient alloy transition joint for submarine cable welding |
| abstract | The invention discloses a preparation method of a copper-aluminum gradient alloy transition joint for submarine cable welding. The method of mechanical alloying is used in advance to prepare copper-aluminum composite powders with different copper/aluminum ratios respectively, and then through layered composite electrodeposition The copper-aluminum gradient connecting material is prepared by the process, and aluminum is used as the cathode. Before deposition, a thin layer of composite powder is evenly spread on the upper surface of the aluminum cathode, and copper is used as the anode. Copper ions are deposited on the aluminum cathode plate and the pores of the composite powder are filled; Layer-by-layer thin layers of copper-aluminum composite powder are deposited, layer-by-layer, to achieve a gradient change in the copper/aluminum ratio in the height direction during the laying process. The aluminum-copper gradient material is prepared by combining gradient layer-by-layer laying of composite powder and composite electrodeposition process, which can effectively avoid the generation of aluminum brittle phase, realize the designable transition of copper/aluminum ratio, and achieve a good combination between composite powders; the principle of this method Simple, fast forming rate, can realize gradient change of material composition, and strong applicability. |
