Plasma Coating Removal
The plasma spray coating process builds up robust coatings and thermal barriers that can be as much as half an inch thick on a substrate. The material to be deposited — also called the “feedstock” — is often a corrosion-resistant alloy such as stainless steel or nickel. When fed into a plasma torch in the form of a powder, liquid, or wire, the material rapidly melts (at temperatures that can reach 10,000 K) and can then be deposited on a substrate in molten form. The plasma jet launches molten droplets onto a surface, where they quickly flatten, cool, and solidify into a deposit.
Plasma thermal spray coatings are useful for coating parts with resilient layers that ward off corrosion, prevent wear-and-tear from abrasions and impacts, or provide a valuable thermal barrier. However, when these protective layers are damaged or compromised over time, there may be a need to remove the plasma coating and restore or refurbish the part. Plasma removal is possible without base metal attack with the right, certified coating removal services.
Excellent results can be achieved through a combination of acid stripping, media blasting, power washing, and other plasma removal techniques. If necessary, a fully stripped part can then be treated with passivation, fresh platings, or renewed coatings of the substrate.
Coating Removal Services
- Chemical Stripping: Submerging a plasma coated part in a bath of specialized acidic solutions is another common and effective method for the complete removal of a coating material without damaging the substrate beneath it.
- Media Blasting: Blasting essentially means abrading the target surface with a focused stream of fine media so as to break down and strip away the outer material. This technique has two, opposite uses. First, it can be an excellent surface preparation method to optimize a surface for thermal spray coatings. However, it’s also a valuable tool for stripping those same plasma coatings.
- Power Washing: Forceful application of water jets can clean a surface of contamination, strip certain coating materials, or remove traces of products from the cleaning and stripping process.

Our 72,000 square foot facility in central Connecticut makes Metal Finishing Technologies one of the largest plating, finishing, and coating removal providers in the Northeast. With 9 plating lines, an FAA repair station, and a dedicated coating stripping area, we’re equipped to provide all of your metal finishing and MRO coating removal needs with high quality and short turnaround times.
Plasma coating removal is a process that we assign high priority and responsive attention. Not only can you expect efficiency and speed, but competitive pricing and the opportunity to test our capabilities beforehand. We’re willing to work on sample parts to showcase the results you can expect from a full plasma removal job. If you are looking for expedited quoting, industry-best TATs, and world-class performance, MFT is here to meet your needs!
The plasma coating process is effective at protecting the base metal, but only so long as the coating itself remains viable. A thermal spray coating can become damaged over time and exposure to harmful substances or extreme conditions and require removal. Plasma thermal barrier removal services make it possible to safely reverse the spray coating process, expose the base metal without damaging it, restore the substrate to optimum condition, and enable the part to be recoated if needed.
- Open capacity
- Rapid turnaround times (a very high priority process)
- More than 20 years of experience in plasma removal work
- An efficient, proven process with reliable results
- Cutting-edge equipment and continual re-investment in updates
MFT has deep familiarity with current OEM equipment: PW/GE/R-R. Our expert team is prepared to work on plasma coating removal in accordance with required OEM specs.
Monitoring and control of the stripping, blasting, and cleaning processes is critical and can be challenging. Base metal stress can occur if the thermal spray coating removal process is not carefully controlled by a partner with up-to-date equipment and the proper experience.
