Anodization of aluminum and dying with Infrared absorbing materials

无机酸将用来对铝件进行阳极氧化。阳极氧化铝件将通过两种不同的方法单独处理。第一种方法是使用有机颜料进行染色，以获得黑色。花菁的水溶液将被用作红外吸收有机染料。第二种方法是使用无机材料，即氧化钒(VO2)和硫化钴(CoS)，在阳极氧化表面获得黑色涂层。这些含有阳极氧化铝的染料/涂层将被用作我们的特定工业合作伙伴的定制件，这些合作伙伴专门制造光学器件，例如用于地球表面或宇宙飞船的相机的机身部件。

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.
