In this workshop, a wide range of overlay & diffusion coatings are applied on gas turbine hot section parts which include common & advanced MCrAlYs, TBCs (Thermal Barrier coatings), Hardface, Abradable and sealing by thermal spray methods. Internal & External diffusion type Aluminide coatings are also implemented by CVD & Pack Cementation methods.
The activities of this workshop can be classified into the following sections:
- Overlay and diffusion coatings by:
- LVPS (Low Vacuum Plasma Spray)
- APS (Air Plasma Spray)
- HVOF (High Velocity oxy fuel)
- Pack Cementation
- CVD (Chemical Vapor Deposition)
- Finishing Processes
- Vacuum Heat Treatment
- Atmospheric Heat Treatment
- Ceramic Shot Peening
- Root Shot Peening (for gas turbine blades)
- Welding &Assembly (TIG Welding & Spot Welding)
- Brazing
- Penetrant NDT testing (FPI)
- Airflow & Water flow tests
- Frequency Measurement of Rotary parts (blades)
- Moment Weight Measurement and blades Sequencing
