Anodizing, is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of aluminum parts; it increases corrosion and wear resistance, and provides better adhesion for paint primers and glues than bare aluminum. Anodic films can also be used for a number of cosmetic effects, either with coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light. Anodizing is also used to prevent galling of threaded components and to make dielectric films for electrolytic capacitors.  Anodized aluminum surfaces, for example, are harder than aluminum but have low to moderate wear resistance that can be improved with increasing thickness or by applying suitable sealing substances. Anodic films are generally much stronger and more adherent than most types of paint and metal plating, but also more brittle. This makes them less likely to crack and peel from aging and wear, but more susceptible to cracking from thermal stress, which can be reduced by using various sealers. We perform sulfuric anodizing to a number of specifications.  Tri-State also offers re-work capabilities and impregnation solutions for anodized films.
