What Is Hard Coat أنودة?

أنودة الطبقة الصلبة هي طريقة لأنودة الألمنيوم. الأنودة هي عملية كهروكيميائية تقوم بتحويل سطح الألومنيوم إلى أكسيد الألومنيوم. يحسن الأنودة مقاومة المعادن للتآكل, يرتدي ويزيد من المتانة. أنودة الطبقة الصلبة تعزز هذه الخصائص.

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 درجات F., with a current density of 23 إلى 37 amps. The time to hard coat is from approximately 20 minutes to 2 ساعات. The alloy and coating thickness determines the amount of time.

سبائك

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.

اللون

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. بينهم, the metal is less resistant to abrasion, wears better, is harder and resists corrosion.
