What Is Hard Coat 陽極酸化処理?
ハードコートアルマイトはアルミニウムにアルマイト処理を施す方法です。. 陽極酸化は、表面アルミニウムを酸化アルミニウムに変換する電気化学プロセスです。. 陽極酸化により金属の耐腐食性が向上します, 摩耗して耐久性が向上します. ハードコートアルマイト処理によりこれらの特性がさらに強化されます.
Hard Coat Anodizing
Anodizing is designated as Type I or Type II. Hardcoat anodizing is referred to as Type III anodizing.
The Hard Coat Process
Hard anodizing or hard coating uses a sulfuric acid electrolyte to convert the aluminum surface to aluminum oxide. The sulfuric acid bath is approximately 32 degrees F, with a current density of 23 に 37 amps. The time to hard coat is from approximately 20 minutes to 2 時間. The alloy and coating thickness determines the amount of time.
合金
Aluminum alloys will accept anodizing. Alloys higher in aluminum with less copper and silicone will accept the hard coat process better. The type of alloy changes the rate the coating builds up.
色
Hard coat anodizing colors aluminum gray. It can also be dyed, but the colors don’t come out as vibrant as they do with Type I or II anodizing.
Benefits of Hard Coat
Hard coat anodizing gives several advantages over anodizing. その中で, the metal is less resistant to abrasion, wears better, is harder and resists corrosion.
