摘要： A laminated colour change device which exhibits an irreversible colour change upon delamination. The device comprises two layers (11 and 13) capable of generating a colour by a light interference and absorption phenomenon that requires direct and intimate contact between the two layers. One of the layers (11) is a colour-generating metal, such as a valve metal (e.g. tantalum), and the other (13) is an overlying light-transmitting film thin enough to cause light interference effects. The film (13) is produced by coating the colour generating metal (12) with aluminum or an aluminum alloy and then anodizing (preferably porous anodizing) the aluminum to consumption in the presence of an adhesion-reducing agent, e.g. fluoride, that reduces the strength of attachment between the layers so that the laminate can be uniformly and reliably separated at the interface between the adjacent two layers. An overlying layer of transparent or translucent material (14) is normally adhered to the laminate to facilitate the separation of the layers. When the thin film (13) is detached from the colour-generating metal (11), the generated colour is lost, thus providing a colour change that is in effect irreversible. The device can be incorporated into a variety of closable articles or products to provide evidence of opening or tampering, or can be used for other purposes.
摘要翻译：一种叠层变色装置，其在分层时表现出不可逆的颜色变化。该装置包括能够通过需要两层之间的直接和紧密接触的光干涉和吸收现象产生颜色的两层（11和13）。层（11）中的一个是诸如阀金属（例如钽）的发色金属，另一个（13）是足够薄以致引起光干涉效应的上覆透光膜。通过用铝或铝合金涂覆产生颜色的金属（12），然后在存在着色剂的情况下对铝进行阳极氧化（优选多孔阳极氧化）来制造薄膜（13）。氟化物，这降低了层之间的附着强度，使得层压体可以在相邻的两层之间的界面处均匀可靠地分离。透明或半透明材料（14）的上层通常粘附到层压板上以促进层的分离。当薄膜（13）与发色金属（11）分离时，产生的颜色就会消失，从而提供实际上不可逆的颜色变化。该装置可以并入各种可关闭的物品或产品中以提供打开或篡改的证据，或可用于其他目的。

摘要： A method for forming multicolor aluminum alloy part has steps of preparing, surface treating, forming, processing and reprocessing. Preparing comprises providing an aluminum alloy substrate and cleaning with water. Surface treating comprises disposing the substrate in a first electrolytic solution to form a base oxide layer by anodizing. Forming comprises applying a membrane of transparent, acid-proof, insulating plastic on the substrate. Processing has locally removing an area of the membrane and corresponding oxide layer from the substrate and cleaning. Reprocessing has disposing the clean substrate in a subsequent electrolytic solution to form a subsequent oxide layer by anodizing on areas of the substrate exposed by local removal of an area of the membrane.

摘要： A process for producing electronic package components (12, 14) from an aluminum alloy is disclosed. The components have a black color through integral color anodization. The desired color, thickness and surface finish are achieved by regulation of amperage (36). The amperage (36) is rapidly raised to in excess of 8.61 A/dm2 (80 amps per square foot) and then allowed to gradually decrease as a function of oxide growth.

摘要： An electrolytic bath for coating articles of aluminum and its alloys consists essentially of an aqueous solution containing an alkali metal silicate, or hydrofluosilicic acid, a peroxide, a water-soluble carboxylic group containing organic acid and a water-soluble fluoride. A vanadium compound may also be included in the bath whenever the coated articles are intended to be used for decorative purposes. In the process, the aluminum article is immersed in the bath and a voltage shock is applied thereto by imposing a voltage potential between the aluminum metal serving as the anode and a cathode immersed in the bath. The voltage potential is quickly raised to about 300 volts within about 2 to about 10 seconds and thereafter, the voltage is increased gradually to about 450 volts within a few minutes until the desired coating thickness formed.
