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. The vacuum cycle and external rotary vacuum pump, being fully controlled by the Instrument.
