Anodization of aluminum and dying with Infrared absorbing materials

将使用无机酸对铝件进行阳极氧化。阳极氧化铝件将分别采用两种不同的方法进行处理。第一种方法是用有机颜料染色，得到黑色。菁的水溶液将被用作红外吸收有机染料。第二种方法将涉及使用无机材料，即氧化钒（VO 2）以及硫化钴（CoS），以在阳极氧化表面上获得黑色涂层。这些染料/涂层纳入阳极氧化铝将被用作定制件为我们的特定工业合作伙伴谁是专门从事制造的光学设备，如身体部分的相机上使用的地球表面或航天器。

Inorganic acids will be used to anodize the aluminum pieces. The anodized aluminum pieces will be processedindividually by two different methods. The first method will involve dyeing using organic pigments to obtainblack colours. An aqueous solution of cyanine will be used as IR absorbing organic dye. The second methodwill involve the use of inorganic materials, namely, vanadium oxide (VO2) as well as cobalt sulphide (CoS) toobtain black coating on the anodized surface. These dyes/coatings incorporated anodized aluminum will beused as customized pieces for our specific industrial partners who are specialized in the fabrication of opticaldevices such as body parts of the cameras used on the surface of the earth or in the spacecrafts.
