The present invention compared with prior art has the following advantages:
1). resistor external-heating type thermal gradient gas-phase carbon deposition device, draw electrode by water-cooled copper, fall " arc " graphite heater and fastening charcoal/charcoal nut thereof, the outer heating system that between water cooled furnace body and heating element, forms by the Carbon foam heat-preservation cylinder, its device fabrication cost is lower than induction external-heating type thermal gradient cvd furnace, high insulating effect, the electric energy consume is few, saves energy;
2). resistor external-heating type thermal gradient gas-phase carbon deposition device, furnace bottom have graphite carriage, inlet pipe, interior water cooling plant, graphite inner core and charcoal dish precast body, the thermopair that the furnace side enters is formed the sediment chamber, and shove charge is convenient, is convenient to safeguard;
3). fall " arc " graphite heater, adopt charcoal/charcoal nut to be fastened on water-cooled copper and draw on the electrode, high temperature resistant in view of carbon/carbon composite intensity height, can make furnace temperature reach 1200 ℃, and long service life, not fragile;
4). this installs the brake technology of preparing of quiet dish, final quotaion material of main military aircraft, seating plane charcoal, has advance and high reliability features.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
