Fig. 1 is the structure diagram of the experimental rig of the present invention；
Fig. 2 is the flow chart of the test method of the present invention.
Specific embodiment
In order to more fully understand the technology contents of the present invention, technical scheme of the present invention is made with reference to specific embodiment
It is further described and illustrates.
The structure diagram of experimental rig of the embodiment of the present invention is as shown in Figure 1.
The high temperature and pressure test device of the present embodiment includes pressure source 10, isolation cylinder 20 and capstan 50.Pressure source 10
For pressurized cylinder.Capstan 50 connects workpiece to be tested.It is equipped with separator piston 21 in isolation cylinder 20, separator piston 21 is by isolation cylinder
20 are separated into independent two parts 22,23, and a part 23 connects pressure source, and another part 22 connects capstan 50.Isolation cylinder
In 20 liquid gallium medium is filled in the connection part 22 of capstan 50 and capstan 50.When pressure source 10 is to isolation
The separator piston 21 of cylinder 20 applies pressure, and separator piston 21 pushes liquid gallium medium to pass through 50 pressure transmission of capstan to work to be tested
On part 70.
Isolation cylinder 20 is externally provided with isolation cylinder heating and thermal insulation set 30, and isolation cylinder 20 can be heated to more than the melting temperature of gallium.
Capstan 50 is externally provided with pipe tracing set 31, and capstan 50 can be heated to more than the melting temperature of gallium.It is to be tested
Workpiece 70 is placed in test specimen heating and thermal insulation part 60, and workpiece 70 to be tested is heated to test temperature (up to thousand degree).Isolation cylinder
Heating and thermal insulation set 30, pipe tracing set 31 ensure gallium medium for ensureing that gallium medium is not less than the fusing point of gallium medium
Liquid fluidity.
In addition, high temperature and pressure test device further includes to be filled with liquid gallium medium into capstan 50 and isolation cylinder 20
Filling-valve 40.Filling-valve 40 is located on capstan 50 and is connected with capstan 50.Specifically, capstan 50 divides for phase
Intercommunicated horizontal component and vertical portion, filling-valve 40 are located at the intersection of horizontal component and vertical portion, and horizontal component connects
Lead to workpiece 70 to be tested, vertical portion connection isolation cylinder 20.The storage device of 40 external liquid gallium medium of filling-valve, works as filling-valve
During 40 opening, liquid gallium medium enters after capstan 50 portion for entering isolation cylinder 20 and connecting capstan 50 from filling-valve 40
Divide 22, with to be used.After liquid gallium medium is sufficient much of that, need to close 10 work of ability Opening pressure source later of filling-valve 40
Make.
The high temperature and pressure test method of the present embodiment uses the high temperature and pressure test device of the present embodiment and using liquid
Gallium medium is tested.As shown in Fig. 2, test method includes：
Step S1, isolation cylinder 20, capstan 50 and workpiece to be tested 70 are preheating to predetermined temperature range；
Step S2, gallium medium is carried out being preheating to 30 DEG C of temperature or more, it is made to keep molten state；
Step S3, the gallium medium of liquid is filled with to the part of the connection capstan 50 of isolation cylinder 20；
Step S4, Opening pressure source 10 pressurizes to the separator piston 21 of isolation cylinder 20, pushes liquid gallium medium to be tested
The pressurization of workpiece 70 is until off-test；
Step S5, by the gallium dielectric film filter of liquid.
In step sl by opening isolation cylinder heating and thermal insulation set 30, pipe tracing set 31 and test specimen heating and thermal insulation part
60 so that between isolation cylinder 20 and capstan 50 reach 30 degree~50 degree of predetermined temperature, ensure gallium medium enter after energy
Enough ensure liquid, keep mobility, avoid test failure, and temperature range can not cause to scald.And in addition allow work to be tested
Part 70 is heated to test temperature (up to thousand degree or more), reaches experimental condition requirement.
Step S2 is carried out in external gallium media storage devices, it is therefore an objective to by gallium melting media and keep preferably stream
Dynamic property, otherwise the once solidification of gallium medium, can not enter from filling-valve 40 in capstan 50.Preheating temperature needs to be more than that gallium is situated between
The fusing point of matter, but the waste of energy without excessively high.Step S1 and step S2 can be carried out successively, can also be carried out at the same time, also may be used
To be first step S2 and then carry out step S1, but final purpose is that gallium medium is allowed to keep mobility, avoids generating blocking.
In step s3, separator piston 21 is allowed in the centre position of isolation cylinder 20, opening filling-valve 40, external gallium Jie of unlatching
Liquid gallium medium is filled into capstan 50 from filling-valve 40 and connects capstan 50 full of isolation cylinder 20 by matter storage device
Part, the part 22 that isolation cylinder 20 is at least connected to capstan 50 is full of, and separator piston 21 is avoided to reach close to pressurization
Gallium medium does not reach but at workpiece 70 to be tested during the range of pipeline 50, i.e., can not transmit pressure, and experiment can not carry out.
In step s 4, start pressure source 10 and push separator piston 21, separator piston 21 pushes the arrival of liquid gallium medium to treat
At test piece 70, workpiece 70 to be tested starts to be pressurized, and tests formal start.The compression power of workpiece 70 is essentially from pressure source 10
Hydraulic coupling, when need to workpiece 70 apply variation pressure when, directly control 10 output pressure of pressure source.Test period
It can freely determine, can also test to workpiece 70 and damage.The parameters of workpiece 70 can pass through biography during experiment
Sensor detects in real time to be come and records in real time, in order to subsequent analysis and research.
In step s 5, first the workpiece 70 after experiment is cooled to not less than 30 DEG C, the gallium medium of workpiece 70 is poured out back
It receives, the gallium medium in pressure pipeline 50 and isolation cylinder 20 is replaced out with compressed air to be recycled.It is put into after gallium dielectric film filter
Into external gallium media storage devices to treat next use.
In other embodiments, it if test specimen is metal, can be applied on parts surface of the test specimen with liquid-gallium media contact
Upper protective coating avoids gallium medium at high temperature from rapidly diffusing into the lattice of certain metals and generates alloy with many metals.
It is set forth above only with embodiment come the technology contents that further illustrate the present invention, in order to which reader is easier to understand,
But embodiments of the present invention are not represented and are only limitted to this, any technology done according to the present invention extends or recreation, is sent out by this
Bright protection.
