The surface ultrasonic burnishing treatment process for improving uranium material corrosion resisting property to the present invention is described in detail below.
Uranium is a kind of metal that chemical property is extremely active, and the corrosion of uranium material can seriously affect the service life of product,
The corrosion resistance of material can be improved by institutional framework regulation, rolling processing is exactly a kind of method easily and effectively.
But severe plastic deformation, which occurs, for surfacing in rolling process causes energy higher, high activity this for uranium
Serious oxidative phenomena can occur during processing for material；In addition, rolling processing will affect the grain size of material, texture, residual
These influence factors are only carried out Proper Match by many factors such as residue stress, can be only achieved the effect for improving corrosion resistance,
If matching is improper, good metamorphic layer cannot be formed, can accelerate the corrosion rate during uranium material military service instead, therefore for
The rolling processing of high active material needs to design special treatment process according to material structure evolution characteristics.
The present invention is according to the relationship between uranium materials microstructure structure and corrosion behavior, by becoming to during ultrasonic burnishing
The control requirement of shape, has devised the ultrasonic burnishing technique specifically for uranium material, configuration state needed for obtaining on the surface of the material
Metamorphic layer, can obviously improve the corrosion resistance of uranium material after the process.
An exemplary embodiment of the present invention, the surface ultrasonic burnishing treatment process for improving uranium material corrosion resisting property
Specifically: it is rolled again using the ultrasound that rolling pressure head carries out several times to uranium material surface after carrying out surface machining to uranium material

~0.1mm and depressing force F are 200~1000N, roll the feed speed V of pressure head2For 2~10mm/min.
Also, the input supersonic frequency f of ultrasonic burnishing processing be 20~40kHz and rolling pressure head output end amplitude A be 3~
10 μm, A value depends on the plastic property of uranium material, and the poor uranium material of plasticity then chooses lesser A value.
Wherein, the depressing force F acted in ultrasonic burnishing process on rolling pressure head should meet following formula:
F=(k1×D)×(k2× A),
Wherein, k1=0.05~0.15, k2=0.6 × 102~1.5 × 102, D is rolling pressure head diameter, and A is rolling pressure head
Output end amplitude, k1、k2Optimal value depend on processing uranium materials microstructure performance characteristics.
That is, depressing force F value is determined according to the diameter of rolling pressure head and the amplitude binding constant of uranium material property selection,
Initial oxidation caused by so as to weaken in rolling process simultaneously improves Part Surface Roughness, forms one layer of spy on the surface of the material
Fixed metamorphic layer improves the corrosion resistance of uranium material.
Step c:
Follow rest makes rolling pressure head return to initial position and keep drafts Δ X not after completing 1 time ultrasonic burnishing processing
Become, completes the processing of surface ultrasonic burnishing after repeating several processing all over ultrasonic burnishing.
Wherein, the processing pass of ultrasonic burnishing processing is not easy excessively, and preferably 2~3 times.
