Below in conjunction with Fig. 1 to Fig. 2, the infiltration of this utility model embodiment being equipped 100 to be described in detail, the infiltration equipment 100 of this utility model embodiment may be used for preparing metal and ceramic composite, for instance aluminum silicon carbide composite material, but is not limited to this。
Infiltration equipment 100 according to this utility model embodiment can include the first container 110, second container 120, mould 130 and temperature field and control device 140。
Wherein, the first container 110 is airtight and limits the first chamber 101, and the container that the first container 110 is airtight can facilitate follow-up evacuation that first chamber 101 is done to process。
Second container 120 is placed in the first chamber 101 and limits the second chamber 102 for containing infiltration liquid, and infiltration liquid can be melted molten metal, for instance can be aluminum liquid or copper liquid etc.。Owing to second container 120 needs to contain the melt liquid of the high temperature such as molten metal, therefore second container 120 needs high temperature resistant, for instance, second container 120 can be crucible。
Mould 130 is provided with for placing product to be formed (such as, carborundum skeleton) the 3rd chamber 103, being provided with the connectivity structure for connecting the second chamber 102 and the 3rd chamber 103 on mould 130, the infiltration liquid that connectivity structure is configured so that in the second chamber 102 can rely on gravity to enter in the 3rd chamber 103 at least partially through connectivity structure。
It is to say, the infiltration liquid in this utility model embodiment can flow into the 3rd chamber 103 under gravity, simple to operate, safety, without carrying out antigravity operation, for instance relies on pressure to make infiltration liquid flow to mould inside from bottom to top。
Alternatively, connectivity structure can be intercommunicating pore 104, and intercommunicating pore 104 can be arranged on the top of the 3rd chamber 103, and thus infiltration liquid can be entered in the 3rd chamber 103 by intercommunicating pore 104, and generates composite panel with product to be formed under the effect of the pressure。
Control device 140 in temperature field is arranged for the temperature to infiltration liquid and is controlled。For example, it is possible to make temperature in second container 120 keep certain temperature, or gradually reduce the temperature of infiltration liquid in the 3rd chamber 103 from top to bottom, to realize the progressively molding of composite panel。
The work process of the infiltration equipment 100 of this utility model embodiment is briefly described below。
Mould 130 is placed in second container 120, second container 120 is heated, when the temperature of second container 120 reaches setting value, infiltration liquid importing second container 120 until infiltration liquid does not have the connectivity structure on overmolding mould 130, infiltration liquid enters into the 3rd chamber 103 by connectivity structure under gravity；
First chamber 101 is carried out evacuation process, it is to avoid the generation of the internal trickle pore of finished product, noble gas is filled in the first chamber 101 so that the first container 110 is carried out pressurized treatments pressurize a period of time；
Temperature field controls device 140 and controls the temperature of infiltration liquid, the temperature making infiltration liquid gradually reduces on direction from top to bottom, namely first the temperature of infiltration liquid bottom reduces, reduce after the temperature on infiltration liquid top, thus, the infiltration liquid that bottom can be solidified by the infiltration liquid on top gradually carries out solidification feeding；
After having solidified, the first chamber 101 is carried out pressure release process, take out second container 120 and the metal derby of its solidified inside is ejected, then metal derby is cut to take out mould 130, with extractor, the profiled member in mould 130 is ejected。
Infiltration equipment 100 according to this utility model embodiment, the infiltration liquid in second container 120 can enter in the 3rd container under gravity, thus controls simple, safety and is easily achieved。
Additionally, the temperature of the infiltration liquid within second container 120 can control, and then the setting rate of infiltration liquid can be controlled, it is ensured that end product quality, without shrinkage cavity/shrink the defects such as bad。
