Banner CCRS - redirection

The majority of gas turbines require a coating system to protect the components from heat, corrosion or erosion. Component Coating and Repair Services (‘CCRS’) specialise in the development and application of organic and inorganic overlay and diffusion coatings (IP1041), dry film lubricants, barrier coatings and aluminium sacrificial coatings (IP9183). IPCOTE and IPSEAL corrosion protection, erosion protection. Following are the coatings we provide:

Anti-fouling
Dry film lubricants
IPAL diffusion coating for ‘hot end’ sulphidation protection
Smooth-Seal Sacrificial Coating System
Indestructible paint and coating systems (approved equivalent of SermeTel® coatings)
Repair and refurbishment coatings for compressor blades and vanes, combustion/flame tubes, replacement honeycomb seals and re-coating of turbine blades, vanes and nozzle guide vanes (NGVs).
Teflon Coatings
Rockhard Stoving Enamels and Lacquers
Phosphating
Barrier coatings
Aluminium sacrificial coatings

Key characteristics for these coatings are :-

Protect against corrosion and particle erosion
Temperature resistant
No embrittlement of high strength steel
Sacrificial to ferrous alloys
Resistant to aerospace oil, fuel and hydraulic fluid
Suitable for application to both external and internal surfaces – smooth, low profile film
Easily repairable without dismantling or oven curing the component
Environmentally friendly – REACh compliant, water based and solvent free
Durable and damage resistant

CCRS has the capability to process a wide range, size and complexity of components, from small compressor blades to the latest in landing gear components.

Onsite coating services

Bespoke onsite coating application services are also available on request.
