Twin Wire Arc Spray (TWAS) System

At Vacuum Engineering & Materials (VEM), our Twin Wire Arc Spray (TWAS) System provides a durable, cost-effective surface treatment solution engineered for the demanding conditions of thin film deposition and vacuum processing environments.

Designed to enhance component longevity, improve resistance to erosion, and maintain clean, stable process conditions, TWAS is a cornerstone of our advanced surface treatment services.

What Is Twin Wire Arc Spray (TWAS)?

Twin Wire Arc Spray (TWAS) is a thermal coating process that uses two electrically charged consumable metal wires. When the wires meet, an electric arc melts the material, and a high-velocity gas stream propels the molten droplets onto the target surface. The result is a uniform metallic coating that bonds tightly and provides exceptional protection against wear, oxidation, and heat.

At VEM, we apply TWAS coatings to vacuum chamber components and other precision parts that must perform reliably in extreme environments, from high-temperature processing to corrosive conditions.

Benefits of the TWAS System

  • Extended Component Life: TWAS coatings form a strong, resilient barrier that reduces erosion and thermal fatigue, keeping parts in service longer.

  • Enhanced Performance: Treated surfaces deliver improved stability, minimizing contamination and maintaining consistent thin film deposition results.

  • Reduced Downtime: Longer-lasting components mean fewer unplanned maintenance events and smoother production cycles.

  • Cost Efficiency: Extending the life of high-value components lowers replacement costs and total cost of ownership.

  • Versatile Applications: Suitable for both new parts and refurbishment projects across industries including semiconductors, data storage, LEDs, and wireless technologies.

Precision Application in a Controlled Environment

Every TWAS treatment at VEM is performed within our ISO-certified facility in Dallas, Texas, ensuring the highest level of cleanliness, precision, and repeatability. Our expert technicians combine TWAS with precision cleaning and other preparatory steps to guarantee a flawless surface bond and optimal coating performance.
