Type III – Deeper oxide build-up to give a very hard, wear and corrosion resistance surface. Coating takes place in a cooled acid electrolyte. Top Coats for Anodizing. Hardcoat Anodizing: Hardcoat anodizing (also called hard coat anodizing, or hard anodizing) is a process that forms a very hard, dense, and relatively thick coating of aluminum oxide. That is the type of anodizing that takes dye well and is typically used mainly for cosmetic purposes, but also adds a hard aluminum oxide coating to the part that is very corrosion resistant as well as wear resistant and has electrical insulating properties. Hardcoat Anodizing Hard anodizing is a denser, thicker version of anodizing. It is the electrochemical process for producing an extremely hard, dense and wear resistant oxide of aluminum which approaches the hardness of tool steel and corrosion resistance of Stainless Steel. These coatings are applied in thicknesses ranging from .001-.003 in. Hard coat anodizing further enhances these properties. Steve Hall has almost 40 years of experience in the anodizing business. Our Hardcoat line uses the latest technology to give a pore structure so dense, that even your mother would have a hard time damaging it on the stove while making your dinner. Anodizing is an electrochemical process that converts surface aluminum to aluminum-oxide. Kit is for user seeking best looking, semi reflective finish. Comprised of 44 process tanks, the 5000 sq.ft line produces anodizing with high pH sealants and organic die coloring capabilities. As anodizing can be a fussy process, a top coat covering all imperfection can be applied. Following anodizing, some components are sealed while others are Teflon® (PTFE) impregnated without sealing. It is possible to achieve a .002″ thickness with a 50% Penetration and 50% Buildup on the surface. Hard Coat Anodize (Type III) is similar to Anodize in that it increases the thickness of the natural Aluminum oxide layer, though Hard Coat Anodize is a much thicker and harder coating - .001-.002” thick and up to 70 Rc. Hard Anodizing / Hard Coat Anodize. PFI’s powder coating process bakes powdered plastic onto the metal surface, creating a finish that provides a hard, abrasion-resistant, shell.
