Chemical stripping of protective coatings

Image

Successful removal of protective coatings is the first step of the gas turbine overhaul & repair process. The predominant industrial method is complete part immersion in an acid bath solution utilizing concentrated acids such as Hydrochloric, Nitric and Phosphoric.

Electron supplies integrated turnkey chemical coating stripping systems for the efficient removal of diffusion & plasma-applied protective coatings and specifically focused on the gas turbine MRO sector.

In addition, we provide supplementary processing tasks such as acid barrier masking and heat tinting furnaces for successful coating removal inspection and evaluations.

TO CHEMICAL STRIPPING

HFIC superalloy cleaning

Image

Once the component has been stripped of its protective coatings, the next step is a crack defects identification. An HFIC (Hydrogen Fluoride Ion cleaning) furnace will clean and process deep fissure cracks within superalloys.

Electron offers safe and effective methods for cleaning hot-section gas turbine superalloy components. With our customized and customer-specific HF Ion cleaning furnaces, parts can be prepared compliant with OEM process specifications and in advance of vacuum diffusion brazing.

TO HFIC FURNACES

Vacuum diffusion brazing

Image

After HFIC processing, the cleaned & prepared parts are ready for the next thermal treatment process: diffusion brazing with a high vacuum furnace.

Electron provides various horizontal and vertical vacuum furnace designs and with all units supplied as a perfectly matched production combination for maximum operational flexibility.

All vacuum furnace units meet OEM diffusion brazing specification requirements such as:
GE’s ADH process, P&W’s TURBOFIX process, SAFRAN’s BD/RBD process and other OEM or customer-specific braze processing specs.

Tailored to each individual application, we equip a vacuum furnace with high-capacity dry screw/roots vacuum pumping systems, process sized diffusion pumps, rectangular or round hot zone geometry’s, and with Graphite based and/or Molybdenum hot zone chambers available. Our wide range of standard sizes offers a suitable furnace combination with a matching HFIC unit for each particular component.

Platinum electroplating

Image

To increase the service life of hot section superalloy gas turbine components, we offer conventional Platinum electroplating systems & technologies for various processing methods.

Our innovative Platomation system addresses the challenges of maintaining correct plating bath chemistry’s and demanding daily maintenance activities. Platomation processing technology brings genuine productivity gains and is a cost-effective and reliable method for the processing of Platinum electroplating.

TO PLATINUM ELECTROPLATING

Diffusion coating

Image

After stripping, cleaning, brazing and optionally Platinum electroplating, the next stage of processing is to apply protective coatings.

Electron offers high-end diffusion coating furnaces for additional oxidation and corrosion protection of critical hot section components. Thanks to the availability of large process chamber dimensions, our coating furnaces offer high-capacity coating batches.

We are qualified to supply coating furnaces and all supplementary equipment, including slurry type applied coatings, Powder Pack Cementation coatings, VPA coatings and our unique hybrid CVD coating system for component Aluminising. All our coating systems are designed based on many years of practical experience in processing within this highly-specialized and demanding process discipline.
