Hard coat anodizing is a proven electrochemical process that transforms a plain metal surface into an engaging exterior that provides both advanced corrosion-resistance and durability. Anodizing is an electrochemical process that converts surface aluminum to aluminum-oxide. This is called “hard coat” or “hard anodizing”. Surely the whole point of anodising is to make the surface of the aluminium hard? H&W Global offers a hard-coat anodizing service that is most commonly applied for mechanical strength, and to give an abrasive resistant coating. Kit is for user seeking best looking, semi reflective finish. What is a hardcoat anodizing? Hard anodizing Low roughness anodizing process (break master cylinder) Large anodizing thickness coating (up to 150µ) Anodizing from aluminum profiles and others similar with up to eleven meters long. Hard Anodizing / Hard Coat Anodize. These coatings are applied in thicknesses ranging from .001-.003 in. I'm getting ahead of myself, though. You use too much energy and the process time is often prolonged so a soft coating is found on the surface instead of a hard. and they are only found as a black hard coat. Hard coat: Type III, HCA or hardcoat anodizing processes at higher voltages and current densities. It is possible to achieve a .002″ thickness with a 50% Penetration and 50% Buildup on the surface. Voltage, amperage, and cycle times can be tripled or even quadrupled versus regular anodizing. The electrical power of the anodically applied waveform is significantly increased. The porous nature of the anodized layer allows the product to be dyed any color that is required. Hardcoat Anodizing Hard anodizing is a denser, thicker version of anodizing. 60,000 topics spanning 36 years. Hard coat (Uniform anodic coatings) Hardcoat or hard anodizing (Type III) is similar to standard anodizing, (Type II) in as much as it also creates a film of aluminum oxide on the part.
