本発明はアルミダイカスト製品のアルマイト加
工処理法の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved alumite processing method for aluminum die-cast products.
アルミダイカスト素材で鋳造された例えば魚釣

陥がある。 When alumite is applied to the surface of a product cast from aluminum die-casting material, such as a fishing reel, which has excellent aesthetics and corrosion resistance, it is affected by impurities such as silicon oxide, iron, and copper, resulting in so-called hot water. There is a defect in which traces occur, causing color unevenness and making it impossible to dye uniformly.

式は黒色などの濃色染色の場合は良いが、シルバ
ー、ゴールド色などの淡色染色の色むらの発生は
未だ確実に防止することはできない欠陥がある。 In order to prevent this defect, prior to degreasing the aluminum die-casting material, the material is treated with a solution containing hydrofluoric acid or a hydrofluoric acid compound as the main component, and then the surface is polished with a steel ball. It is known from Japanese Patent Publication No. 54-31744 that impurities can be removed to prevent color unevenness, but this method is good for dyeing dark colors such as black, but it is effective for dyeing dark colors such as silver and gold. The occurrence of color unevenness in light-colored dyeing is a defect that cannot yet be reliably prevented.
この原因は前記方式では不純物を除去して形成
される高純度アルミニウム層が１〜5μ程度に過
ぎず、通常のアルマイト層は５〜10μであるため
下層の除去されていない不純物が酸化物を形成し
て灰黒色に発色しこれが淡色染色を黒ずませて色
むらを発生し易いためである。 The reason for this is that in the above method, the high-purity aluminum layer formed by removing impurities is only about 1 to 5 μm in thickness, and a normal alumite layer is 5 to 10 μm in thickness, so the unremoved impurities in the lower layer form oxides. This is because the dye develops a gray-black color, which darkens light-colored dyeing and tends to cause color unevenness.

法によりアルマイト染色加工処理することを要旨
とするものである。 The present invention is intended to improve this defect. After polishing and hydrofluoric acid treatment on the surface of an aluminum die-cast material, high-purity aluminum is deposited in a vacuum, and then the high-purity aluminum adhesion layer is removed using a conventional method. The gist of this is that the alumite is dyed and processed.

色を簡易に行うようにしたものである。 The method of the present invention is to vacuum-deposit high-purity aluminum with a thickness greater than the thickness of the alumite forming layer on the surface of an aluminum die-casting material, and then process this high-purity aluminum layer with alumite to prevent the occurrence of color unevenness in light-colored alumite dyeing. It is possible to easily dye alumite in any color with good appearance and corrosion resistance while reliably preventing the staining.

を行う。 To explain the details of the present invention, a cast aluminum die-cast material (purity 80-82%) is degreased with alkali or surfactant as usual, and then subjected to polishing such as barrel polishing and shot barrel processing, and hydrofluoric acid treatment. After that, a high purity aluminum coating layer (purity 99.4) is applied to the surface by vacuum evaporation method.
% or more), and then this high-purity aluminum adhesion layer is subjected to steel ball polishing, shot blasting, chemical polishing, etc. as necessary, and then sequentially degreasing treatment, activation treatment, anodizing treatment, etc. according to conventional methods.

る。 However, since the high-purity aluminum adhesion layer usually has a thickness of about 5 to 10 μm,
Approximately 20μ is preferable. Also, to give an example of the vacuum evaporation method mentioned above, the product to be treated is set in a vacuum tank with a capacity of 10 -5 TORR or more, inert argon gas is introduced, and high voltage is applied to the inside of the vacuum tank. High-purity aluminum is evaporated and deposited on the surface of the workpiece by glow discharge for about 15 minutes, and the thickness of the deposited film can be adjusted arbitrarily by changing the discharge time.

Then, after 10 seconds of activation treatment with a 20% hydrofluoric acid solution, it was set in a vacuum tank of 10 -5 TORR, and inert argon gas was introduced to generate a glow discharge.
