machining
Metal
Strong & tough
" Heavy
" Chemically
reactive,
" Limitations on
max operating
temperature
Polymer
Light & cheap
- Chemically
inactive
" Easy tofabricate
" Used at
temperatures
below 300C only
ZrO2,
SiC, Si3N4
I,
Ceramic
" High-temp strength
" Superior wear
resistance
Lower thermal &
electrical conductivity
" Chemical stability
" Retention of these
properties at high
alumina and emphasizes on experimental and
computational approaches
in understanding
physical nature of the complex phenomena.
