Description
Technical field
This disclosure relates to the material properties test technical field of experiment equipment in liquid lead bismuth corrosion and ion irradiation environment,
More particularly to a kind of corrosion of control oxygen liquid lead bismuth and ion irradiation cooperating research experimental provision and method.
Background technology
Liquid lead bismuth eutectic (LBE) has good neutronics, physics and chemical property, is that lead base generally acknowledged at present cools down

Split target material.It is served in the working condition that LBE is faced as the structural material in coolant or the Advanced Nuclear Energy Systems of spallation target
Very severe, not only by high temperature, strong irradiation, but also also deep-etching caused by liquid lead bismuth.Liquid lead bismuth is to metallic based structures
The corrosion behavior of material is broadly divided into oxidation corrosion and dissolved corrosion, related with the oxygen concentration dissolved in liquid lead bismuth.In height
Oxygen (＞ 10-6Wt%) in environment, the metallic atom of metallic based structures material internal is inwardly spread to external diffusion, O ions, in material
Surface can form metal oxide layer, oxide layer, which grows to certain thickness and is easy to happen, to fall off, so increase line clogging windward
Danger.In hypoxemia (＜ 10-8Wt%) in environment, metal material Fe, Ni and Cr element can largely be dissolved in corrosive medium, cause structure
Element quality loses, to reduce the mechanical load ability of material.Based on the development of control oxygen technology, by accurately controlling liquid lead
Dissolved oxygen concentration in bismuth, be allowed to material surface formed one layer of densification, the moderate metal oxide layer of thickness, can effectively prevent or
Liquid lead bismuth is delayed to corrode.In neutron irradiation environment, the irradiation defect that will produce inside structural material and surface oxide layer (
Gap and vacancy), due to irradiating enhanced diffustion effect, oversaturated defect can lead to the diffusion system of alloying element in metallic matrix
Number greatly increases.In addition, irradiation formed highdensity dislocation structure be considered as a metal ion species and O ions diffusion it is fast
Fast channel, it can thus be anticipated that, there is certain synergistic effect in the material in neutron irradiation and liquid lead bismuth corrosion.The association
Same-action effect is to be designed as such nuclear-energy plant with having very one of critical issue of high priority in construction and receive weight
Depending on, but the research for corroding synergistic effect to neutron irradiation/liquid lead bismuth at present is seldom, and acquired experimental data also has very much
Limit, which part the reason is that due to related experiment device shortage.Chinese patent 2013106302246 mentions a kind of ion irradiation
Corrode synergistic effect research experiment device with liquid lead bismuth, is ground with liquid lead bismuth corrosion synergistic effect although realizing irradiation substantially
Study carefully, but lack liquid lead bismuth oxygen concentration control system, can only generally carry out the Research on synergistic effect under saturated oxygen concentration conditions.This
Outside, current liquid lead bismuth circuit generally also lacks necessary Fluid pressure detecting system, and experiential function is relatively single.
