压铸铝合金外观件表面处理方法及压铸铝合金外观件制品
摘要：
本发明提供了一种压铸铝合金外观件的表面处理方法和压铸铝合金外观件制品，该表面处理方法包括：以铝为阳极，以压铸铝合金外观件为阴极，对压铸铝合金外观件进行离子镀膜处理，以在压铸铝合金外观件表面形成镀铝层；对进行离子镀膜处理后的压铸铝合金外观件进行阳极氧化处理，以在压铸铝合金外观件表面形成氧化膜层。本发明提供的压铸铝合金外观件的表面处理方法，在进行阳极氧化处理之前，在外观件的表面形成一层镀铝层，由于镀铝层中不含Si、Fe、Cu等元素，有效的保证了阳极氧化的效果及后续染色效果，且工艺简单，成本低，外观件的正品率高。
摘要（英）：

The invention provides a surface treatment method of a die-cast aluminum alloy exterior part and a die-cast aluminum alloy exterior part product. The surface treatment method includes the steps that aluminum serves as an anode, the die-cast aluminum alloy exterior part serves as a cathode, and the die-cast aluminum alloy exterior part is subjected to ion plating treatment so that an aluminum coating can be formed on the surface of the die-cast aluminum alloy exterior part; and anodic oxidation treatment is conducted on the die-cast aluminum alloy exterior part subjected to ion plating treatment so that an oxide film layer can be formed on the surface of the die-cast aluminum alloy exterior part. According to the surface treatment method of the die-cast aluminum alloy exterior part, the aluminum coating is formed on the surface of the exterior part before anodic oxidation treatment is conducted, and the aluminum coating does not contain Si, Fe, Cu and other elements, so that the anodic oxidation effect and the subsequent dyeing effect are effectively guaranteed. Besides, the process is simple, cost is low, and the qualified rate of die-cast aluminum alloy exterior parts is high.
