The invention discloses an automatic nanocrystalline
metal composite material preparation furnace through reaction under protection of high temperature and
high pressure gas. The preparation furnace comprises a double-
ferrule gas inlet
needle valve, an automatic decompression valve, a pressure gage, a
pressure sensor, a first sealing
flange, red
copper seal rings, a high temperature
alloy steel tube, a reaction sample boat, a second sealing
flange, a vent valve, a
heating furnace hearth and a
metal plate furnace body, wherein two
water cooling fixed mounts are symmetrically mounted on the twosides of the
metal plate furnace body; the
heating furnace hearth is arranged in the metal plate furnace body; the high temperature
alloy steel tube penetrates through the metal plate furnace body andthe
heating furnace hearth; the reaction sample boat is fixedly connected with the interior of the high temperature
alloy steel tube; the two ends of the high temperature
alloy steel tube are in sealing connection with the first sealing
flange and the second sealing flange separately through the red
copper seal rings; and the automatic decompression valve is fixedly connected with the bottom of the first sealing flange. According to the automatic nanocrystalline metal
composite material preparation furnace through reaction under protection of high temperature and
high pressure gas, nano material and metal material have
high pressure synthesis reaction under the protection of high temperature and
high pressure gas to obtain high-quality
composite material.
