一种在铜排表面浸镀铝层的方法
摘要：
本发明涉及一种在铜排表面浸镀铝层的方法，包括以下步骤：1）用砂纸对铜排表面进行打磨处理，并用140-150℃蒸汽处理10-20min；2）将蒸汽处理后铜排置于70-75℃的碱液中碱洗30-40min，取出再用140-150℃蒸汽处理3-5min，最后用清水冲洗；3）将碱洗后的铜排置于30-35℃酸液中酸洗10-15min，取出再用140-150℃蒸汽处理1-2min，最后用清水冲洗；4）将步骤3）处理的铜排均匀喷射一薄层粘接剂，并控制厚度在0.5-0.6mm，然后进行烘干处理；5）将步骤4）处理的铜排置于680-700℃的铝液中，浸泡20-25s，取出后自然冷却；6）将浸镀好的铜排在800-900℃氧化处理，即得成品。本发明镀锡效率高，质量好，铜排的镀锡层表面亮度亮、光滑平整，镀层结晶均匀、细致，耐腐蚀性能强，致密度高且不脱落。
摘要（英）：

The invention relates to a method for immersion plating of an aluminum layer on the surface of a copper bar. The method comprises the following steps: 1) grinding the surface of the copper bar with abrasive paper, and steaming the copper bar for 10-20min at 140-150 DEG C; 2) putting the steamed copper bar in alkali liquor at 70-75 DEG C to be washed by alkali for 30-40 min, taking out the copper bar and steaming the copper bar for 3-5 min at 140-150 DEG C, and finally washing the copper bar with clean water; 3) putting the copper bar washed by alkali in an acidic liquid at 30-35 DEG C to be pickled for 10-15 min, taking out the copper bar, then steaming the copper bar for 1-2 min at 140-150 DEG C, and finally cleaning the copper bar with clean water; 4) spraying a thin adhesive uniformly to the copper bar treated in the step 3), controlling the thickness at 0.5-6.0mm, and then drying the copper bar; 5) putting the copper bar treated in the step 4) in aluminum liquor at 680-700 DEG C tobe soaked for 20-25s, and taking out the copper bar and naturally cooling the copper bar; and 6) oxidizing the copper bar treated by immersion plating at 800-900 DEG C to obtain a finished product. The method provided by the invention is high in tinning efficiency and good in quality, the tinned layer of the copper bar is high in surface brightness and smooth and level, and a plated layer is uniform and fine in crystal, high in corrosion resistance and high in compactness, and does not fall.
