Determine what NADCAP Anodizing Is to Boast Being a Supplier to American Aerospace

In a few words, NADCAP anodizing involves an extremely rigorous processing session and diligent adherence to distinct steps, procedures, and systems to get the product finishing required by Aerospace and Defense. It entails procedures including Boric Acid Sulfuric Acid Anodizing (BSAA), Chromic acid anodizing (CAA), Thin Film Sulfuric Acid Anodize (TFSAA), Sulfuric Acid Anodizing (SAA) and Phosphoric Acid Anodizing (PAA). The outcome of these procedures is highly improved corrosion protection, durability ( sun-glo.com/services/anodizing ), adhesion quality for painting and general adhesiveness (that comes through CAA, TFSAA, and BSAA), in addition SAA includes abrasion resistive quality.

An Overview: NADCAP Anodizing

 NADCAP Boric Sulfuric Acid Anodizing (BSAA)

BSAA anodizing standard has been developed by Boeing Aircraft cells being a changeover from traditional chromic acid anodize with a view to defy increasing environmental adversities. The product of BSAA is completely different from so called sulfuric acid anodize, while it yields a superior coating which is very thin and having steadiness to all sorts of deterioration.

 NADCAP chromic acid anodizing (CAA)

CAA standard must be meeting all requirements formulated by Mil-A-8625, (Type I and IB) and AMS 2470. Despite the fact that chromic acid offers a thin deposit of coating, however, it has been established as a superlative means to guard corrosion when compared to its counterparts. In addition, CAA includes exceptional quality for pre-treatment required for painting processes.

 NADCAP sulfuric acid anodizing (SAA)

SAA Anodize coating provides extremely abrasion resistance opposed to average anodizing procedures. Equivalent to hardcoat anodizing, SAA provides pretreatment and adhesion capability for paint and dry films with amazing competence.

 NADCAP Phosphoric Acid Anodizing (PAA)

PAA anodizing process involves developing film onto various aluminum substrates that are principally required for structural bonding adhesiveness. Typically it is needed for flight control applications and has been developed by the US Boeing Company for its specific needs.

Notably, from cleaning to finishing NADCAP anodizing procedure directs its suppliers to stand by several guidelines as mentioned by the authority.

Cleaning: Aluminum substrates should be cleaned through acid wash, alkaline cleaning, or ultrasonic vapor degreasing means. Followed by general cleaning, objects needs to be pre-treated to attain the desired level of reflectivity which can include highly reflective gloss finish ( http://www.sun-glo.com/blog/ ), low luster finish and matt monish.

Anodizing: As per BSAA, CAA, TFSAA); SAA and PAA

Sealing: Post anodizing seal options are widespread and an essential element of NADCAP anodizing systems. Depending the on class of anodizing procedure, ‘sealing’ process vary in terms of its specification in order to meet the need of its applications.
