CARBON AND METAL EVAPORATORS: K450X
- K450X Automatic Carbon Coater with
Flash Evaporation:
The
K450X uses
several Carbon Fibre types to cover a
range of deposition thicknesses operating
at rotary vacuum pressures. Coating
is omni-directional, and this fully Automatic System has a
relatively short cycle time of the
order of 5 minutes.
The system employs low voltage, high
current, electrodes between which the carbon fibre is located. The
electrode assembly employs a
protective shutter to protect the specimen from the heat radiation
damage during the timed outgassing of the carbon fibre process. At
completion of this process, the shutter automatically retracts, and full
power is applied to the electrodes, causing the carbon to burn quickly
or 'flash' the fibre fusing as part of the process. At this point, the
shutter returns to the protective position.
The controls can be preselected to allow
for different types of carbon fibre. This,
together with adjustable specimen stage to electrode distance, and fully
automatic control, allows repeatable deposition thickness to be achieved.

by the Instrument.
