铜钢组合件钎焊氧化皮去除法北京航空工艺研究所（１０００２４）朱彦海在焊接过程中，钢和铜因受高温作用而在其表面生成厚氧化皮。用化学浸蚀法去除，要将钢零件放到含有铜离子的酸中，使钢表面附上置换的铜，而这置换的钢又很难从钢表面上去掉。因此，在除锈时应尽量避... Copper and steel assembly brazing oxide removal Beijing Institute of Aeronautical Technology (100024) Zhu Yanhai In the welding process, steel and copper due to high temperature and the surface to generate thick oxide scale. To remove by chemical etching, place the steel part in an acid containing copper ions to attach the displaced copper to the surface of the steel, which is hard to remove from the steel surface. Therefore, rust should be avoided as far as possible ...
