Automatic nanocrystalline metal composite material preparation furnace through reaction under protection of high temperature and high pressure gas

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of synthesis and reaction equipment for metal nanocomposite materials, in particular to an automatic high-temperature and high-pressure gas reaction nano-metal composite material preparation furnace. Background technique [0002] At present, hot pressing equipment is used to make synthetic materials, pressurize up and down in a closed cavity, and burn at a certain temperature to produce composite materials by pressing while burning. The determination of this process is that the direction of force is only up and down, so that There are obvious defects in the quality of materials. And some gas source high pressure reaction tests cannot be realized during the test. Contents of the invention [0003] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an automatic high-temperature and high-pressure gas reaction nano-metal composite material preparati...
