In the aerospace and defense industries, precision, durability, and compliance are non-negotiable. Every part, from a tiny fastener to a massive structural assembly, must meet strict quality and performance standards. One of the most critical steps in achieving these standards is metal finishing — the process of enhancing a component’s surface to improve corrosion resistance, wear properties, and overall performance.
When it comes to selecting NADCAP metal finishing companies, experience and capability make all the difference. White Oak Manufacturing Solutions represents one of the world’s top providers of NADCAP-accredited aerospace metal finishing, offering a full range of certified processes that meet the most demanding specifications.
Why NADCAP Certification Matters
The National Aerospace and Defense Contractors Accreditation Program (NADCAP) is the gold standard for special process certification in aerospace manufacturing. Achieving NADCAP accreditation requires passing intensive audits that validate technical competence, process control, and quality assurance.
Working with a NADCAP-certified metal finishing company ensures:
- Full compliance with aerospace and defense specifications
- Consistent, repeatable quality in every batch
- Reduced risk of part rejection or rework
- Confidence in meeting both domestic and international standards

Core Aerospace Metal Finishing Processes
A world-class NADCAP metal finishing company offers a wide variety of specialized processes tailored to aerospace applications. Below is a breakdown of the processes available through one of the best providers in the industry:
1. Anodizing
An electrochemical treatment for aluminum that enhances corrosion resistance, surface hardness, and paint adhesion. Available in chromic, sulfuric, and hard-coat variations for different performance needs.
2. Cadmium Plating
A sacrificial metallic coating that provides exceptional corrosion protection, especially in marine and salt-rich environments. Common for aerospace fasteners and hardware.
3. Chemical Film Treatment
Also known as chromate conversion coating, this process improves corrosion resistance and acts as a base for paint or adhesive bonding.
4. Chrome Plating
Applies a hard, wear-resistant chromium layer for durability, corrosion protection, and a reflective finish.
5. Dry Film Lubricant
A specialized coating that reduces friction and wear without liquid lubricants — ideal for high-temperature or vacuum environments.
6. Electroless Nickel Plating
Deposits nickel evenly on complex parts without electrical current, creating a uniform, corrosion-resistant coating.
7. High-Temperature Aluminum Coating
Protects parts exposed to extreme heat, such as engine components, while maintaining corrosion resistance.
8. Nickel Cadmium Plating
Combines nickel and cadmium layers for superior corrosion resistance at elevated temperatures. Often used in landing gear components.
9. Nickel Plating
Enhances wear resistance, corrosion protection, and conductivity. Can be decorative or functional.
10. Passivation
A chemical cleaning process for stainless steel that removes surface contaminants and restores corrosion resistance.
11. Phosphate Coating
Provides corrosion protection and serves as an excellent base for paint or other finishes.
12. Prime and Paint
Aerospace-grade primers and paints provide UV stability, corrosion protection, and part identification.
13. Silver Plating
Boosts electrical conductivity while offering moderate corrosion resistance. Common in electrical connectors and contacts.
14. Strip and Blast
Removes old coatings or contaminants and prepares the surface for re-coating or inspection.
15. Titanium Clean
Specialized cleaning process for titanium to remove oxides and contaminants before further processing.
16. Zinc Nickel Plating
An alloy coating that offers superior corrosion resistance over traditional zinc, especially in harsh environments.

Quality Control in NADCAP Metal Finishing
For aerospace components, even a small surface defect can lead to costly failures. NADCAP-certified facilities implement rigorous quality assurance protocols including:
- Coating thickness measurement
- Adhesion and hardness testing
- Corrosion resistance evaluation (salt spray testing)
- Electrical conductivity verification
- Visual and microscopic inspections
These checks ensure each part meets exacting aerospace requirements before leaving the facility. Reach out here to work with a provider that embeds quality at every step.
Aerospace Applications for Metal Finishing
Metal finishing processes are used in nearly every part of an aircraft or spacecraft, including:
- Landing gear assemblies – protected against corrosion and wear
- Engine components – finished for heat resistance and durability
- Aircraft fasteners – plated for corrosion resistance and conductivity
- Cabin interior hardware – anodized for aesthetics and protection
- Satellite structures – coated for thermal control and radiation protection
The right finishing process can dramatically extend a component’s service life and improve operational performance. Consult with an expert to match your part’s environment with the ideal coating or plating.
