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).
