What Is Hard Coat Anodizing?
Anodizing ya kanzu ngumu ni njia ya anodizing aluminium. Anodizing ni mchakato wa elektroni ambao hubadilisha alumini ya uso kuwa oksidi ya alumini. Anodizing inaboresha upinzani wa metali dhidi ya kutu, kuvaa na kuongeza kudumu. Anodizing ya kanzu ngumu huongeza zaidi mali hizi.
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 kwa 37 amps. The time to hard coat is from approximately 20 minutes to 2 masaa. The alloy and coating thickness determines the amount of time.
Aloi
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.
Rangi
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. Kati yao, the metal is less resistant to abrasion, wears better, is harder and resists corrosion.
