A method of forming an interference film on an aluminum alloy substrate includes the following steps: providing an aluminum alloy substrate; cleaning the aluminum alloy substrate through a pre-treatment process; performing an anodic treatment on the aluminum alloy substrate for a predetermined amount of time till an oxidized film having a plurality of cellular tubes is formed on the surface thereof; expanding the holes of the oxidized membrane of the aluminum alloy substrate with an acidic solution to enlarge the diameter of the cellular tubes; enlarging the bottom of the cellular tubes to form a deposition area through an electrical enlarging process; depositing a metal material on the deposition area of the cellular tubes to form an interference structure; sealing the cellular tubes with a sealing agent; and removing dirt. Furthermore, an interference film structure is formed on the aluminum alloy substrate using the aforementioned method.

A surface treatment for metal surfaces can be used to create one or more desired effects, such as functional, tactile, or cosmetic effects. In one embodiment, the treatment involves selectively masking a portion of the surface using a photolithographic process. The mask can protect the masked portion of the surface during subsequent treatment processes such as texturizing and anodization. The mask can result in the creation of a surface having contrasting effects. A pattern can be formed by the contrasting effects in the shape of a distinct graphic, such as a logo or text.

An anodized layer on a metallic substrate is treated in a manner to directly electrodeposit a metal sulfide solid lubricant material represented by MS2, where M is Mo, W or other suitable metal, in pores of the anodized layer without any subsequent thermal and/or chemical treatment being needed.

An anisotropically conductive member includes an insulating base having through micropores and conductive paths formed by filling the through micropores with a conductive material, insulated from one another, and extending through the insulating base in its thickness direction, one end of each of the conductive paths exposed on one side of the insulating base, the other end of each of the conductive paths exposed on the other side thereof. The insulating base is an anodized film obtained from an aluminum substrate and the aluminum substrate contains intermetallic compounds with an average circle equivalent diameter of up to 2 μm at a density of up to 100 pcs/mm2. The anisotropically conductive member dramatically increases the density of disposed conductive paths and suppresses the formation of regions having no conductive paths, and can be used as an electrically connecting member or inspection connector for electronic components.

摘要:
A method of manufacturing a magnetic recording medium having a discrete track structure enables the discrete track structure to be fabricated in a simple method with good productivity while maintaining satisfactory accuracy of the discrete track structure and holding favorable magnetic separation performance between tracks. The method comprises steps of: forming an aluminum film on a nonmagnetic substrate; executing an anodizing process on the aluminum film to form an alumina layer including nano-holes in a self-organizing manner; forming a resist pattern exposing recording track regions; and depositing a magnetic material in the nano-holes in the recording track regions. The method can further comprise a step of forming recessed parts at positions of the nano-holes to be formed in the anodizing process. The method can further comprise a step of forming a first underlayer of titanium and a second underlayer of gold.
摘要:
A method is disclosed for defining discrete magnetic and non-magnetic regions on the magnetic film layer of a storage media substrate. The method applies anodic oxidation of a cobalt-containing magnetic film layer to remove cobalt, followed by controlled deposition of a non-magnetic matrix into the regions where the cobalt has been removed. Deposition may either be electrodeposition, collimated vacuum deposition, or other methods depending upon the composition of the non-magnetic matrix being deposited. The method may be performed in a single electrochemical cell.
摘要:
In a method of manufacturing a microstructure, an aluminum member having an aluminum substrate and a micropore-bearing anodized layer present on a surface of the aluminum substrate is subjected at least to, in order, a pore-ordering treatment which involves performing one or more cycles of a step that includes a first film dissolution treatment for dissolving 0.001 to 20 wt % of a material constituting the anodized layer and an anodizing treatment which follows the first film dissolution treatment; and a second film dissolution treatment for dissolving the anodized layer, thereby obtaining the microstructure having micropores formed on a surface thereof. This method enables a microstructure having an ordered array of pits to be obtained in a short period of time.
