MANUFACTURING

ALLOYS

  • All TSL blades and vanes are manufactured with Super alloys

    • Super Alloys are a class of material that represent the highest level of alloy chemistry and process metallurgy in current aerospace and land based power generation industry. Super alloys run at 90% of their melting point.

  • All hot section part manufactured by TSL are prepared from controlled virgin/remelt ratios using Vacuum Slag Remelt (VSR) or Electro Slag Remelt (ESR) to ensure cleanliness of alloy

  • TSL requires certified chemical/mechanical properties of sample coupons or test bars for each master melt lot to ensure the integrity of the alloy.

  • Manufactures both Equiax and Directionally Solidified parts

TSL TOOLING

  • All capital parts tooling are owned by TSL

  • Each capital part has a complete set of tooling

    • Wax injection tooling

    • Assembly fixture

    • Checking gauges

HEAT TREATMENT

  • Castings are thermally processes for optimum strength

QUALITY CONTROL PLAN

  • TSL requires first article sample piece to validate suppliers’ casting process

  • Supplier submit process demonstration report

  • Independent testing of first article to validate supplier’s process

  • Regular on site audit to ensure uniformity of processes

MANUFACTURING

CONVENTIONAL MACHINING

  • Parts are machined to finished dimensions using

    • Stress free grinding, Turning, Milling

  • TSL owns all machining tooling

NON CONVENTIONAL MACHINING

  • Internal Cooling holes and other features are inserted by

    • Electric discharge machining (EDM)

    • Shaped Tube Electrochemical Machining (STEM)

    • Electrochemical Machining (ECM)

  • Internal Cooling holes are used to keep the core material of the blades and

  • vanes cool at running temperatures

QUALITY CONTROL PLAN

  • TSL requires first article sample piece to validate supplier’s process

  • Supplier submit manufacturing process plan

  • TSL conduct internal dimensional inspection to validate part

  • Regular on site audit to ensure uniformity of processes

Slide 15

Turbine Services Limited

Replacement Parts for GE Design Large Frame Gas Turbine Parts

MANUFACTURING

  • TSL applies all the updated coating to our turbine parts namely:

    • Thermal Barrier Coating TBC

      • For enhanced heat resistance

    • Chemical Vapor Deposition (CVD) Aluminide

      • In cooling passages to resist corrosion and oxidation

    • Stellite strips inserts by High Velocity Oxy Fuel (HVOF)

      • Increases wear resistance of parts by acting as sacrificial wear agent

    • Duplex Coating Systems (MCrAlY, NiCoCrAlY, CoNiCrAlY)

      • Applied to allow blades and vanes to operate at high temperatures by resisting oxidation and corrosion

      • Preserves the strengthening mechanisms of the base material

    • Plasma Coating

      • Increases corrosion resistance.

  • TSL also Shot Peen blades to add compressive surface stress the structure and HIP (Hot Isostatic Pressing) to eliminate microporosity.
