Arc Spray Equipment

Astro Alloys offers TAFA® arc thermal spray systems and equipment, which are engineered to maximize simplicity, durability and repeatability regardless of your coating application.  This process involves two wires that are fed into the gun, they are then charged and an arc is generated between them.  The heat from the arc melts the incoming wire and the molten feedstock is then deposited on the substrate.

TAFA Model 8830MHU / 8835MHU

TAFA Arc Spray System

The TAFA Models 8830MHU and 8835MHU puller arc spray systems are proven performers, consistently delivering high-quality coatings with minimal operator adjustment. They’re designed to optimize particle atomization and spray pattern distribution, ensuring optimal coating repeatability. Both models offer high deposition efficiency and produce good bond strength, uniform microstructure and excellent machining properties.

Arc Spray Applications

Praxair has worked closely with the industry to develop arc spray solutions for some of the most demanding industries including:

Aircraft Component Repair- Most major aircraft engine manufacturers specif the use of the arc spray process to repair many aircraft engine components. Thermal spray coatings are applied to various components for dimensional restoration, hot temperature erosion reistance, and as bond coats.

Heavy Equipment Repair- The heavy equoment industry uses arc spray to restore worn components as well as repairing surface defects on new components. These coatings have proven their excellence in challenging environments such as the repair of large diesel engine decks. Application of the coatings can occur at OEM manufacturing sites or at after-market repair facilities. 

Power Generation-  The arc spray process is used in the power generation industry for coatings that procide corrosion protection, part restoration, and life extension. 

Part Restoration-  The forgiving nature and flexibility of the arc spray process enables economical application of thick coatings without significant loss of bond strength. Because of this, arc spray has become the process of choice for part restoration in applications where the replacement costs are high, or the part has to be refurbished on-site. 

Arc Spray Equipment Benefits

Praxair's advanced arc spray equipment offers the following benefits but are certainly not limited to:

  • Higher deposition efficieny
  • Higher particle velocities
  • Denser coatings
  • Focused, narrow spray pattern
  • Superior bond strength
  • Smoother as-sprayed coating
  • More uniform microstructure
