The plasma spray coating process involves spraying a substrate with molten or semi-molten material to create a hard coating that protects against oxidation and corrosion wear caused by environmental and operating conditions. The coatings are dense and strong, making plasma coating a favorable option for equipment protection and refinishing.

Plasma Spray Coating Process

Plasma spray coatings are applied using a high temperature process that involves injecting powdered coating material into a plasma flame. The material is rapidly heated and then accelerated toward the substrate. Once it reaches the surface it begins to cool, forming a hard coating on the substrate. The high temperatures involved in plasma coating allow the use of ceramics and other materials that have a high melting point.

Plasma spray coating is a highly versatile process that is used by industries including:

Enhancing Durability and Wear Resistance Using Plasma Spray Coatings

ASB Industries’ plasma spray coating processes utilize heat energy to reach the melting point of the chosen ceramic chemistry. Plasma coatings are applied using spray guns that feature water-cooled copper anodes and tungsten cathodes. The plasma gas flows around the cathode and then through the copper anode. A high voltage discharge initiates an arc that creates extreme temperatures, which causes the plasma to form as the plasma flame mixes with the powder. The result is a hard coating adhered to the surface of the substrate.

This versatile system creates ceramic coatings that can protect components in even the most severe environments. Ceramic plasma spray coatings provide:

  • High Temperature Resistance
  • Extreme Wear Resistance
  • Inert Chemical Resistance

Availability of Materials Makes Plasma Coating a Versatile Process

The ability to use a range of materials makes plasma spray coating a highly versatile process. A few of the common materials ABS Industries uses for plasma spray coating processes include:

Thickness specifications are based on the component application, including wear and corrosion considerations. Along with multilayered coating systems, we will utilize specialized sealing treatments to optimize coating performance. Specialized coating materials may also be available upon request. Contact ASB Industries to discuss your material requirements.

ISO Certification and Documented Procedures for Plasma Spray Coating

Throughout the plasma spraying process, documented procedures are recorded for each job, and on-going inspections are performed for each critical step. Both the plasma spray control panel and our closed loop powder feeders are precisely calibrated to produce consistent coating quality.

All equipment is calibrated to ISO standards to optimize the injection of powder into the plasma jet, which ensures the proper melting of powdered materials. All lot numbers from our powder suppliers are recorded and, in most cases, sample pieces are processed for testing purposes during production spraying.

Effective Protection for A Range of Applications on Plasma Electric Arc Spray

Plasma Electric Arc Spray is an established thermal spray process that is commonly used for numerous applications across many industries. Aircraft turbine engines, land based turbines, and other applications that could achieve greater operating efficiencies with high temperature protection are prime examples. In the chemical industry, chemical corrosion, abrasive wear, erosion, and cavitation are common challenges that can be solved with the application of ceramic coatings using the plasma spray process.

If electrical current is an issue, plasma electric arc spray coatings also provide dielectric shielding. These coatings can prevent current from passing through critical components and causing harmful arcing. With the added protection of a plasma spray coating, components are shielded from potentially severe electrical corrosion and damage to bearing components.
