Our Anodizing Services
Anodizing aluminum is an essential process used in the aerospace industry for improving both the durability and aesthetic appeal of aluminum components and parts. This involves passing an electrical current through an electrolyte solution containing aluminum, creating a protective layer of aluminum oxide on its surface. This oxide layer protects from corrosion, wear, and abrasion while improving the strength and longevity of aluminum parts.
Benefits
- Anodizing increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than does bare metal. Anodic films can also be used for some cosmetic effects with thinner transparent coatings or thicker porous coatings that can absorb dyes.
- The anodizing process changes the microscopic texture of the surface and changes the crystal structure of the metal near the surface. Thick coatings are porous, so a sealing process is often needed to achieve corrosion resistance.
- Anodized aluminum surfaces, for example, are harder than aluminum, but can have good 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.
