What Is Thermal Spray Aluminum (TSA) Coating?
Thermal Spray Aluminum (TSA) coating is a highly effective corrosion protection method that involves spraying molten aluminum particles onto a substrate using arc or flame spray techniques. The process creates a metallurgically bonded layer that provides exceptional resistance to corrosion, abrasion, and chemical damage.
How It Works
- Arc/Flame Spray Process: Aluminum wire is melted using an electric arc or combustion flame, and the molten particles are propelled onto the surface using compressed air.
- Bonding: The aluminum particles solidify upon impact, forming a dense, adherent coating that protects the underlying material.
- Sealing (Optional): A sealer or topcoat can be applied to enhance durability and resistance to specific environments.
Benefits of TSA Coatings
- Superior Corrosion Resistance: Aluminum forms a passive oxide layer that prevents rust and degradation, even in harsh marine or industrial environments.
- Durability: TSA coatings can last 20+ years with minimal maintenance, making them ideal for long-term asset protection.
- Versatility: Suitable for steel, concrete, and other substrates, TSA coatings can be applied to complex geometries and large structures.
- Cost-Effective: Compared to stainless steel or other corrosion-resistant alloys, TSA coatings offer a more affordable solution without sacrificing performance.
Why Choose TSA Coating?
Superior Corrosion Resistance
TSA coatings provide outstanding protection against:
- Saltwater and marine environments (ideal for ships, offshore platforms, and coastal infrastructure).
- Industrial chemicals and pollutants (suitable for refineries, chemical plants, and storage tanks).
- Atmospheric corrosion (protecting bridges, pipelines, and structural steel from rust and weathering).
Long-Lasting Protection (20+ Years)
Unlike traditional coatings that may degrade over time, TSA coatings maintain their integrity for decades. This extends the lifespan of assets, reducing the need for frequent repairs or replacements and lowering long-term maintenance costs.
Compliance with Industry Standards
TSA coatings meet stringent international standards, including:
- ISO 2063: Standard for thermal spraying of metallic and other inorganic coatings.
- NACE SP0108/SSPC-CS 23: Standards for corrosion protection of steel structures.
- ASTM B117: Salt spray test for evaluating corrosion resistance.
By adhering to these standards, TSA coatings ensure reliability, safety, and compliance with industry and regulatory requirements.
Our TSA Application Process
At Vivablast, we follow a structured and precise process to apply TSA coatings, ensuring maximum protection and durability for your assets.
Surface Preparation
Proper surface preparation is critical for coating adhesion and performance. Our process includes:
- Grit Blasting: Using abrasive media (e.g., aluminum oxide or steel grit) to clean the surface and create a rough profile for optimal bonding.
- Cleaning: Removing dust, grease, and contaminants to ensure a clean substrate.
- Degreasing: Eliminating oils and residues that could compromise adhesion.
Thermal Spray Application
Our certified technicians use state-of-the-art equipment to apply TSA coatings with precision:
- Arc Spray: Uses an electric arc to melt aluminum wire, producing a high-velocity spray for efficient coverage.
- Flame Spray: Utilizes a combustion flame to melt aluminum, ideal for detailed or small-area applications.
- Coating Thickness: Typically applied at 100–300 microns, depending on the environmental conditions and project requirements.
Inspection and Quality Control
To ensure coating integrity and performance, we conduct rigorous inspections and tests, including:
- Visual Inspection: Checking for uniformity, adhesion, and defects.
- Thickness Measurement: Using magnetic or ultrasonic gauges to verify coating thickness.
- Adhesion Testing: Performing pull-off tests to assess bonding strength.
- Holiday Detection: Identifying pinholes or discontinuities using high-voltage testing.
Our quality control processes ensure that every TSA coating meets ISO 2063, NACE, and client-specific standards.
