    • PURPOSE: A method of manufacturing aluminum alloy with a groove unit and a protruded undercut is provided to strongly maintain the bonding state of an aluminum alloy material and a resin material since an aluminum alloy structure covered with a fine groove unit and a protrusion unit is put into a mold and then resin composition is insert-injected. CONSTITUTION: A method of manufacturing aluminum alloy with a groove unit and a protruded undercut comprises next steps. Aluminum alloy is shaped by die casting or mechanical processing. Oil components adhered from the shaping process are removed using surfactant. The oil-removed aluminum alloy is immersed in alkali solution of 10~100 g/l. Foreign materials and an aluminum oxide film are removed from the immersion process, and the surface activated aluminum alloy is etched by acid solution of 100~300 ml/l, which is selected from hydrochloric acid, sulfuric acid, and nitric acid.
    • 目的:提供一种制造具有凹槽单元和突出底切的铝合金的方法,以强烈地保持铝合金材料和树脂材料的粘合状态,因为放置有细槽单元和突出单元的铝合金结构 进入模具,然后插入树脂组合物。 构成:制造具有凹槽单元和突出底切的铝合金的方法包括以下步骤。 铝合金通过压铸或机械加工成型。 使用表面活性剂除去从成型过程粘附的油组分。 除油铝合金浸入10〜100 g / l的碱溶液中。 从浸渍工艺中除去异物和氧化铝膜,用盐酸,硫酸和硝酸选择100〜300ml / l的酸溶液蚀刻表面活性铝合金。
