WHY FGM ?

Delamination of composite materials No compromise with desirable properties High abrasion resistance High impact resistance Convenience: weldable/boltable to metal

supports

CLASSIFICATION OF FGM

Thin FGM:-it consist of relatively thin sections or thin surface coating.

Bulk FGM:-it consist of volume of materials which require more labour intensive processes.

PROCESSING TECHNIQUES OF THIN FGM Vapour Deposition techniques(i.e.PVD,CVD) Plasma Spraying Self-propagating High temperature synthesis

(SHS) Ion Beam Assisted Deposition (IBAD)

1.VAPOUR DEPOSITION TECHNIQUE

2. PLASMA SPRAYING

3.SELF PROPAGATAING HIGH TEMP. SYNTHESIS (SFS)

4. ION BEAM ASSISTED DEPOSITION

PROCESSING TECHNIQUES OF BULK FGM Powder metallurgy technique Centrifugal casting method Solid freeform technology

1. POWDER METALLURGY TECHNIQUE

2. CENTRIFUGAL CASTING PROCESS

3. SOLID FREE FORM TECHNOLOGY SFF involves five basic steps: Generation of CAD data from the software

like AutoCAD, Solid edge etc. Conversion of the CAD data to Standard

Triangulation Language (STL) file Slicing of the STL into two dimensional

cross-section profiles Building of the component layer by layer Removal and finishing.

3. SOLID FREE FORM TECHNOLOGY

MAJOR APPLICATIONS OF FGM Aerospace Medicine Defense Energy Optoelectronics

OTHER APPLICATIONS OF FGM Cutting tool insert coating Automobile engine components Nuclear reactor components Turbine blade Heat exchanger Fire retardant doors Sensors

CONCLUSION Importance of FGM in engineering and

other applications. Flexibility in manufacturing of FGM. Bringing down the fabrication cost

through improving the most promising fabrication method (SFF).
