一、序言铝及其合金由于重量轻、加工性能良好,因此被应用在装饰、防腐、产品轻量化、降低成本等方面。但是,铝因为它的性质柔软,容易划伤和腐蚀,所以不能以其原状态使用。为了提高耐机械疲劳性、耐蚀性及装饰性等性能,一般要对铝制品进行氧化及涂漆等表面处理。对铝氧化膜过去利用其耐蚀性,着色后主要应用于装饰上,但是最近对过去的铝氧化膜改良后,制得了又厚又硬的氧化膜,这种硬质
First, the preamble Aluminum and its alloys due to light weight, good processing performance, it is used in decoration, anti-corrosion, lightweight products, reduce costs and so on. However, aluminum can not be used in its original state because of its soft nature, easy scratching and corrosion. In order to improve resistance to mechanical fatigue, corrosion resistance and decorative properties, generally aluminum products for oxidation and painting surface treatment. In the past, the aluminum oxide film used its corrosion resistance and was mainly used for decoration after coloring. However, recently, after the improvement of the past aluminum oxide film, a thick and hard oxide film was obtained, and this kind of hard
