Phosphoric Anodize

In the multifaceted department of aerospace finishes, one process stands as a cornerstone for producing components that are not only resilient but also perfectly primed for bonding. That process is phosphoric acid anodize. Essential to the aerospace industry, this electrochemical treatment is the key to ensuring aluminum parts endure the rigors of their application environments while maintaining their structural integrity.

 

What Is Phosphoric Anodize?

Phosphoric anodize is a specialized form of anodizing that uses phosphoric acid to create a protective oxide layer on the surface of aluminum parts. This process is essential in the aerospace industry, where metal components must withstand extreme conditions and adhere reliably to structural adhesives. Let’s explore the specifics and the impact this innovative treatment has on aircraft components.

 

The Science Behind Phosphoric Anodizing For Aircraft Components

Phosphoric anodizing is more than a simple coating; it’s a scientific method that significantly enhances metal surfaces. By immersing aluminum parts in a phosphoric acid solution and applying an electrical current, an oxide layer forms on the surface. This layer improves corrosion resistance and ensures better adhesion for paints and bonding agents, critical for the assembly and longevity of aircraft.

 

Understanding Phosphoric Anodize And Its Applications In Aviation

Aviation relies on phosphoric anodize for its unique properties that guarantee safety and efficiency. This treatment method supports various applications, ensuring parts perform at their best when it matters most.

 

Priming Surfaces For Adhesive Bonding

Crafting an aerospace structure demands precision and enduring bonds, and here phosphoric anodize acts as a key preparation step. It meticulously conditions aluminum surfaces to create an exceptionally receptive base layer for adhesives, facilitating unions that define the aircraft’s structural resilience. The precise nature of Valence’s anodizing process ensures the uniformity of this crucial layer, providing reliability in the performance of every bonded joint.

 

Enhancing Corrosion Resistance

In the battle against corrosion, the oxide layer bestowed by phosphoric anodize is an aluminum component’s first line of defense. This protective shield mitigates the decaying effects of oxidative elements, safeguarding the integrity of each part. By extending the resistance to corrosion, Valence’s expertly applied anodizing services prolong the service life of components that are essential to the safe operation of every aircraft.

 

Improving Paint Adhesion

Consider the life of an aircraft—it must withstand velocities and altitudes that would compromise lesser finishes. Phosphoric anodize offers an optimal surface that not only firmly anchors paints but also contributes to their vibrancy and longevity. Valence understands that paint adhesion goes beyond cosmetic appeal; it is a critical layer that serves both brand representation and protective functionality.

 

Ensuring Part Longevity

The ultimate test for any aeronautical component is time itself. Phosphoric anodizing imbues parts with the resilience necessary to sustain the ceaseless demands of flight. This process is instrumental in decreasing the likelihood of fatigue and wear, allowing aerospace components to serve safely over extended periods.

Valence offers every variety of anodizing, including but not limited to:


Type I Anodize

  • Boric Anodize – Boric-Sulfuric Acid Anodize (BSAA) is an alternative to chromic acid anodize (CAA), that builds a thin-film anodic coating and provides corrosion protection and a mechanical bond. This is a nonchromated, environmentally friendly solution.
  • Tartaric Anodize – Tartaric-Sulfuric Anodize (TSA) is an alternative to chromic acid anodize (CAA), that builds a thin-film anodic coating and provides corrosion protection and a mechanical bond. This is a nonchromated, environmentally friendly solution – typically specified in Airbus programs like the A350.
  • Chromic Anodize – Chromic Acid Anodize (CAA) creates the thinnest anodic coating, while providing the same corrosion resistance as other types of anodization, such as boric or sulfuric.

Type II Anodize

  • Sulfuric Anodize – Sulfuric Acid Anodize (SAA) is used when hardness and abrasion resistance is required on a part, and creates a surface that is harder than traditional chromic anodizing.

Type III Anodize

  • Hard Anodize – Hardcoat anodize is created is a sulfuric acid bath, but results in a much thicker surface anode coating than traditional sulfuric acid anodizing.

Phosphoric Acid Anodize

  • Phosphoric Acid Anodize – Phosphoric Acid Anodize (PAA) is most commonly used in bonding applications, as it provides a superior porous surface for bonding to composites.
