What Is Surface Treatment?
Surface treatment involves applying specialized coatings or processes to metal surfaces. These treatments protect against rust, chemical exposure, and wear, making them essential for industries where parts must endure harsh conditions.
Silvex’s surface treatment solutions adhere to ISO 9001:2015 and NADCAP-certified standards, ensuring consistent, high-quality results that meet or exceed industry requirements.
Types of Surface Treatments at Silvex
Black Oxide
Black oxide is a conversion coating that enhances corrosion resistance while providing a sleek, non-reflective black finish. Commonly used in the defense industry, this treatment also reduces friction and improves wear resistance.
Citric Passivation
Passivation is a process that removes free iron and contaminants from stainless steel surfaces, creating a thin, protective oxide layer that prevents rust and oxidation. This treatment is crucial for aerospace, medical, and industrial applications where cleanliness and corrosion resistance are essential.
Chemical Film (Chem Film)
Also known as chromate conversion coating, the chemical film creates a corrosion-resistant layer on aluminum surfaces while maintaining electrical conductivity. This treatment is widely used in aerospace and electronics applications to protect parts without interfering with their functionality.
Manganese and Zinc Phosphate
Manganese and zinc phosphate coatings enhance durability, wear resistance, and corrosion protection for steel and iron components. Manganese phosphate is ideal for high-friction applications like firearms and industrial machinery, while zinc phosphate provides an excellent base for paint or lubricants. These treatments improve adhesion for oils and coatings, ensuring long-lasting performance in aerospace, defense, and heavy equipment manufacturing.

Frequently Asked Questions
What are surface treatments and why are they important?
Surface treatments modify a material’s surface to improve corrosion resistance, wear performance, paint adhesion, or appearance without altering the base material’s core properties.
How do I choose between plating and surface treatments?
Plating deposits a new layer of metal, while surface treatments modify the existing surface. Your choice depends on the desired function—our team can help identify the most cost-effective and performance-appropriate option.
Are Silvex’s surface treatments RoHS compliant?
Yes, many of Silvex’s surface treatments can be specified to meet RoHS compliance. We can assist in selecting the appropriate process for your regulatory needs.
Do surface treatments affect the dimensions of my parts?
Some treatments like passivation and chemical film add minimal thickness, while others may have measurable buildup. We can advise you on tolerances based on your specs.
What industries benefit from specialized surface treatments?
Aerospace, defense, medical, and electronics sectors all use surface treatments to ensure part longevity and compliance with stringent performance standards.
