经过钎焊后的铝及其复合合金材料,通过热水清洗,除去粘附的钎剂(炉盐),随着清洗水中含炉盐量的增加,是否会引起严重的腐蚀呢?我们进行了试验,取得了数据,为某些全铝结构的焊后清洗工艺提供了依据。一、试验材料用来进行试验的材料有纯铝、单面复铝硅、双面复铝硅、单面复铝锌四种材料,制成长、宽为25×50毫米的试片。二、试验条件与试验程序
After the brazing of aluminum and its composite alloy materials, hot water through the wash to remove the adhesion of the flux (furnace salt), with the increase in the amount of salt contained in the washing water, will cause serious corrosion? We conducted Test, obtained the data, provided the basis for some all-aluminum structure after-welding cleaning process. First, the test materials used to carry out the test materials are pure aluminum, aluminum single-sided aluminum, aluminum double-sided aluminum, aluminum aluminum single-sided four materials, made of long, wide 25 × 50 mm of the test piece. Second, the test conditions and test procedures
