Plasma Coating Corporation (PCC)


Part of the Southwest United Industries family, Plasma Coating Corporation specializes in providing coating solutions to industrial and aerospace customers. Our primary business is the application of thermal spray coatings to aircraft, aerospace, and industrial parts. Our coating processes include HVOF, plasma, wire-arc, and combustion powder and wire. Plasma Coating Corporation's highly skilled and experienced workforce, extensive grinding capacity, and complete painting facilities allow us to provide our customers a range of finished products - both new and repaired.

We have provided the highest quality of metal finishing services for more than twenty-five years. Our primary goal at Plasma Coating Corporation is to provide high quality finishes and services delivered on a consistent, timely basis. We are continually seeking ways to improve our processes and services from the time we receive your part to the time your part is final inspected and shipped. Focusing on understanding our customer’s requirements and continuously working to adapt to an ever changing industry has provided us the opportunity to prosper and grow, while providing our customers the satisfaction of knowing their parts will be completed right the first time, every time.

Plasma Coating Corporation maintains quality system and metal finishing process approvals from most of the major prime contractors. We are constantly working to refine the processes we currently employ, and are always looking on the horizon to stay current with the latest technology. We maintain a balanced approach between production and quality. It is not just how much, but how well.

Southwest United Industries was acquired by Precision Castparts Corp. in December, 2012.


Plasma Coating Corporation services are designed to meet your thermal spray, painting, and grinding needs for newly manufactured parts and for repair and overhaul applications. We operate from a 20,000 square foot modern facility in Gardena, California including substantial new thermal spray and grinding equipment.


Thermal Spray

  • HVOF
  • Plasma
  • Wire Spray
  • Flame Spray

Thermal spraying allows high performance coating applications of materials such as metals, alloys, ceramics, and carbides to be applied to relatively easy-to-work and more economical base materials to significantly enhance the component performance such as wear, heat, oxidization, and corrosion resistance.

Thermal spray coatings:

  • are commonly used in the overhaul and repair of damaged or worn components
  • offer a cost effective and timely alternative to purchasing replacement parts
  • are widely accepted for use in diverse industries such as aerospace and oil and gas
  • have been approved for numerous new airplane production applications by Boeing and Airbus

Thermal spray technology has improved dramatically in recent years. Designers now commonly use thermal spray to enhance the performance of their products rather than as a last resort repair process.

Plasma Coating Corporation is continually investing in new technologies, production capacity, and techniques to meet the demanding standards of our customers.  Our coating engineers work closely with our customers and industry researchers to stay on the leading edge of thermal spray technologies and develop new materials and enhancements.


Painting or organic finishing is often used to provide improved corrosion resistance. Plasma Coating Corporation offers complete painting and other thermal spray related services as part of our complete thermal spray service.

Painted finishes can be specified for a number of purposes. The decisions to plate or paint a specific application will often depend on the following considerations:

  • Cost - Generally, on a per-unit, surface-area basis, organic coatings will tend to cost less than plated deposits.
  • Appearance - The broad range of colors and textures of painted surfaces often make it the finish of choice over plating.
  • Corrosion resistance - In many cases, a properly selected paint coating applied over the pretreatment will perform better in outdoor exposures than a plated one.

Thermal spray and painting complement each other in providing the best choices of finishes.

Plasma Coating Corporation is familiar with the best coating systems for improving corrosion resistance on steel, reducing oxidation on aluminum, and other benefits from painting.
