Background technology
Zirconium, titanium material belong to rare precious metal, and its alloy has very high intensity, high temperature resistant possess certain anti-corrosion
Property, it is applied to special occasions, such as nuclear reactor, high temperature spit tube, steel alloy is micro to add composition etc..
But its heat conductivity is high, pyroreaction and high temperature ablation performance are relatively weak, such as pure in nuclear power plant reactor
Zirconium pipe, when running into the high-temperature high pressure water in presurized water reactor, can react displacing hydrogen, easily occur when running into oxygen or air quick-fried
Fried accident, heat conductivity height can cause hot loss of energy, the presurized water reactor in reactor under 300 DEG C about water temperatures, pipe temperature
Also close to 300 DEG C, under pipe outer wall is acted on air or sea water fog, cause the fast erosion of pipeline outer wall.
Content of the invention
The present invention is to solve the above problems, there is provided a kind of carry out top layer crystalline substance porcelain to the zirconium after processing, titanium and its alloy
Zirconium, titanium and its alloy surface handling process processing.
A kind of zirconium of the present invention, titanium and its alloy surface are processed uses brilliant porcelain formula of liquid, and brilliant porcelain formula of liquid is according to as follows
Percentage by weight is prepared:
Edta is 4-8%, sdbs is 3-6%, vcl3For 1-4%, na2b4o3For 8-12%, nb-re be 2-6%, koh4-8% its
Yu Weishui.
It is preferably, brilliant porcelain formula of liquid is prepared according to following percentage by weight: edta is 5%, sdbs is 4%, vcl3For 2%,
na2b4o3For 10%, nb-re be 4%, koh be 6%, remaining be water.
It is preferably, brilliant porcelain formula of liquid is prepared according to following percentage by weight: edta is 6%, sdbs is 5%, vcl3For 2%,
na2b4o3For 12%, nb-re be 5%, koh be 5%, remaining be water.
A kind of zirconium of the present invention, titanium and its alloy surface handling process, make in accordance with the following steps:
First, use metal cleaner cleaning workpiece, remove greasy dirt；
2nd, the brilliant porcelain liquid preparing is added in process liquid bath, described process liquid bath adds anelectrode, and workpiece adds negative electricity
Pole, power supply adopts alternating source；
3rd, circulating cooling water pipe is installed, for controlling the temperature of brilliant porcelain liquid, brilliant porcelain liquid temperature outside described process liquid bath
Spend for less than 50 DEG C；
4th, supply voltage is 180v, and electric current is 200a, and alternative frequency is 800hz, and the brilliant porcelain time is 60 minutes；
5th, take out workpiece, dry, polished exterior surface.
Compared with prior art beneficial effects of the present invention are as follows.
1. workpiece surfaces externally and internally can form brilliant porcelain layer, and its hardness reaches 0.15mm up to hv1300, depth, has very strong resistance to
Corruption, high temperature resistant ablative and wearability, through test corrosion resistant up to standard salt fog test more than 1200 hours, in strong acid and highly basic
In (concentrated sulphuric acid, nitric acid, hydrochloric acid, sodium hydroxide) do not react.In high pressure-temperature water (300 DEG C) completely can exclusion of water with
Zirconium, titanium and its alloy base material react.
2. its good thermal insulation can make heat-energy losses reduce 10%.
3. limit thermal shock test is up to more than 3000 times (900 DEG C 5 DEG C), bending 180 degree, no cracking phenomenon, repeatedly
Folding 180 degree, until brilliant porcelain no falls block obscission after fracture.And spray, the technique such as vacuum ion sputtering plating is all unable to reach this
Effect.
4. process costs are relatively low, relatively cost performance height (compared with vacuum ion sputtering depositing process).
5. used in the present invention crystalline substance porcelain liquid can Reusability, only do the interpolation of active ingredient, no any poisonous and harmful
Emission of substance, consumes seldom, the use of the energy is electric energy, is environmental protection project.
