一、概述铝及铝合金材料广泛地用于航空工业。为了进一步扩大它的应用范围和提高铝及铝合金的耐磨性能,对铝制品多采用硬质阳极氧化的方法,但这一工艺目前还存在着膜层光洁度差、脆性大、零件尖边锐角处膜甚易脱落、氧化过程中经常出现电腐蚀和不易获得较厚膜层等缺点。因此,本文将着重论述产生这些缺陷的主要原因—界面温度的影响及如何提高硬质阳极氧化产品质量的问题。所谓界面温度或叫孔穴温度,是指零件表 First, an overview of aluminum and aluminum alloy materials are widely used in the aviation industry. In order to further expand its scope of application and improve the wear resistance of aluminum and aluminum alloys, the use of hard anodized aluminum, but this process there are still poor film finish, brittleness, the sharp point of the sharp edges The film is very easy to fall off, often appear during the oxidation of electricity corrosion and difficult to obtain thicker film and other shortcomings. Therefore, this article will focus on the main reason for these defects - interface temperature and how to improve the quality of hard anodized products. The so-called interface temperature or hole temperature, refers to the parts table
