Compound, so that the fusing point of metal be substantially improved.
Therefore the leakproofness that liquid alkali metal Dynamic Corrosion experimental provision 100 provided in this embodiment is more demanding, it is ensured that long
It is few enough by diffusing into the air in reaction chamber in time heating process, it is unlikely to influence liquid lithium corrosion process.And
The experimental provision is installed in glove box by monolayered vessel difficult sealing with reaching pre-provisioning request.By the Ar in glove box
Protective atmosphere (vapor and O lower than 1ppm2), the influence of foreign gas is reduced to greatest extent.
In addition, since sample carries out in glove box, to avoid glove box medium temperature from spending height, so that influencing rubber gloves
Service life (and then the air-tightness for reducing equipment).By thickening the heat-barrier material in heating device, i.e. pedestal 101 and cover board
103 thickness is realized.
The course of work for the liquid alkali metal Dynamic Corrosion experimental provision 100 that the embodiment of the present invention provides is (with alkali metal
For lithium), liquid lithium isothermal Dynamic Corrosion experimental provision is designed, for studying different temperatures, duration and sample and liquid alkali gold
(sample is fixed on blade 176, there is opposite fortune when blade 176 rotates, between sample and liquid lithium under category relative speed
It is dynamic), the Corrosion Protection of coating sample or test button.
When being tested using liquid alkali metal Dynamic Corrosion experimental provision 100, the device is placed in glove box first
It is interior, on condition that glove box will accommodate the liquid alkali metal Dynamic Corrosion experimental provision 100.
Sample is fixed on blade 176 again, then agitating shaft 175 and the sealing pivot of magnetic fluid seal 172 is mutual
Connection, is put into a certain amount of solid metallic lithium particle in the accommodating cavity of accommodating member, by mixing component 15 and closing heating component
10 is fixed, is sealed by graphite-seal ring, guarantees its air-tightness.It is heated by heating member 12, when being warming up to 300 DEG C or more
When (lithium metal thawing), then pass through lifting assembly 18 for the reduction of 176 position of blade, blade 176 and sample is made to be immersed in liquid lithium
In, meanwhile, mixing component 15 starts to stir, and is continuously heating to set temperature and keeps the temperature.After experiment, lifting group is first passed through
Part 18 rises blade 176, and blade 176 and sample is made to be detached from lithium liquid level, then natural to the accommodating cavity of closing heating component 10
It is cooled to room temperature.Cover board 103, first flange 131 and accommodating member are finally disassembled in glove box, by sample from blade 176
It removes, carries out corrosion sample detection and analysis.
After liquid lithium solidification, the lithium that the blade 176 and sample being immersed in lithium can be cured coats completely, it is difficult to take
Out.Therefore mixing component 15 is driven to be risen or fallen by lifting assembly 18.
In experiment heating process, since the time is more long, in order to keep the normal operation of magnetic fluid seal 172, need
It is cooled down.Water circulation system is generallyd use, is cooled down.
Liquid alkali metal Dynamic Corrosion experimental provision 100 provided in an embodiment of the present invention has the beneficial effect that
Design it is reasonable, ingenious, it is compact-sized, it is small in size, can be placed in glove box and be tested, it is at low cost, favorably
It is easily operated in the basic research for carrying out liquid alkali metal Dynamic Corrosion, it is practical.
It should be noted that in the absence of conflict, the feature in embodiment in the present invention can be combined with each other.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
