The dual finishing process uses the best each process has to offer, anodizing with its hard wear resistance and chromate conversion coating with its electrical conductivity. The process steps can typically involve chromate conversion coating the entire component, followed by a masking of the surface in areas where the chromate coating must ...
Top-view scanning electron microscopy image of AAO . Anodic aluminum oxide, anodic aluminum oxide (AAO), or anodic alumina is a self-organized form of aluminum oxide that has a honeycomb-like structure formed by high density arrays of uniform and parallel pores.
anodizing – electrolytic passivation process used to increase the thickness of the natural oxide layer, producing a porous surface which can accept organic or inorganic dyes easily. In the case of titanium, niobium, and stainless steel, the colour formed is dependent on the thickness of the oxide (which is determined by the anodizing voltage).
You'll also often see "anodized" or "hard-anodized" aluminum, too, which is a process that makes aluminum more durable. Both aluminum and anodized aluminum are commonly used as the base for ...
But Calphalon’s signature style, hard-anodized aluminum is designed with durability in mind. It has a nonstick surface for easy cooking and cleanup, but the try-ply construction ensures it'll ...
Photosensitive anodized aluminum was qualified to Federal Specification GG-P-455 in 1965, a document that outlines the performance of Type 1 and Type 2 photosensitive anodized aluminum. [3] Since qualification to GG-P-455, photosensitive anodized aluminum has been specified by many military, government and industrial organizations, including:
In the aluminum industry, the process is also called chemical film [13] or yellow iridite, [13] Commercial trademarked names include Iridite [13] and Bonderite [14] (formerly known as Alodine, or Alocrom in the UK). [15] The main standards for chromate conversion coating of aluminium are MIL-DTL-5541 in the US, and Def Stan 03/18 in the UK.
Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.
