Detailed description of the invention
Compared with research in the past, the creativeness of the present invention is:
1) gallium oxide (Ga it is found that2O3) " kelvin effect " can further improve CsF-RbF-AlF3" the striping of brazing flux
Ability ", thus invented aluminium alloy, Q235 steel and 304 rustless steel spreading property more preferably New type soldering fluxes.
The kelvin effect of high frequency electric is a kind of natural phenomena in physics's (electromagnetism), is generally well known.But
It is that, in brazing process, " kelvin effect " of certain oxide or halogenide is rarely reported.The inventors discovered that, at CsF-
RbF-AlF3In brazing flux, add the Ga of extremely trace2O3(0.0001 mole～0.02 mole), can make the spreading area of solder carry
High by about 50%～90%.By finding the solder surface " energy spectrum analysis " sprawled, there is " substantial amounts of " Ga on the solder surface sprawled2O3,
And the edge that solder is sprawled, Ga2O3" relative quantity " higher than the Ga of solder middle part sprawled2O3Content, thus deducibility
Its chemical reaction mechanism is due to Ga2O3Kelvin effect so that Ga2O3" quickly " can flow, and then promote CsF-RbF-
AlF3The flowing of brazing flux, thus improve spreading ability and the spreading area of solder.
From accompanying drawing 1～Fig. 8 it can be seen that at CsF-AlF3Adding RbF in brazing flux, can significantly improve solder sprawls face
Long-pending；But, at CsF-RbF-AlF3Brazing flux adds the Ga of trace again2O3, it is also possible to improve the spreading area of solder further.
Fig. 1, Fig. 3, Fig. 5, Fig. 7 are the comparing results on the basis of Fig. 2, Fig. 4, Fig. 6, Fig. 8.As space is limited, this specification is only given
Zn-2Al solder is on 5052,6063 aluminium alloys, Q235 steel, the 304 rustless steel mother metals, along with sprawling of gallium oxide changes of contents
The curve of areas and comparison example are along with the spreading area curve of rubidium fluoride RbF changes of contents.But, Al-12Si, Al-Si-Zn pricker
The spreading area change of material is roughly the same with the variation tendency of Zn-2Al solder.
For the ease of test and with pertinent literature Data Comparison, Fig. 1～Fig. 8 all uses mass percent, but with theory
Result in the molar fraction span of design is the most identical.In Fig. 1 Yu Fig. 3, Ga2O3Mass percent reaches 0.009%
Time, spreading area change tends towards stability, but in Fig. 5 Yu Fig. 7, Ga2O3Mass percent reaches spreading area when 0.05%
Change just tends towards stability.
Due to Ga2O3Stable and price is far below GaF3, therefore, add Ga2O3The above-mentioned excellent properties obtained, raw in reality
In product, there is good economic benefit.
2) gallium oxide (Ga it is found that2O3), the mechanism of action of CsF and RbF, thus preferably determine Ga2O3, CsF and
The interpolation scope of RbF.
By brazing flux is added 0.0001mol.% gallium oxide, mate Zn-2Al solder, with 5052,6063 aluminium alloys 500
DEG C reaction XRD analysis of reaction residues of 3 minutes is it was found that all there are Cs in reaction residues11O3、MgGa2O4Occur；With
Q235 steel, 304 rustless steels in 500 DEG C of reactions XRD analysis of reaction residues of 3 minutes it was found that reaction residues all has
AlPO4、FePO4Occur (seeing accompanying drawing 10, Figure 11).
Teach that to the above results " abnormal magical ", with the addition of Ga2O3CsF-RbF-AlF3Brazing flux and aluminium alloy table
During the oxide-film reaction in face, " extremely trace " Ga2O3Participation reaction i.e. " can be enriched with " and play an important role, and with MgGa2O4
Form occur, illustrate brazing flux with than Al2O3The reaction of more stable MgO is also " effect is notable ".RbF then has no residual
Slag occurs as " compound phase ", the compound " Dispersed precipitate " of Rb is described, plays a part " catalysis ", " helping weldering "；CsF is then
Always with Cs11O3Form occur, illustrate CsF really with Al2O3, MgO there occurs chemical reaction, replaced Al2O3, in MgO
O atom, this result " explains " in Fig. 1, Fig. 3 along with Ga2O3The increase of addition, Zn-2Al solder closes at 5052,6063 aluminum
On gold, spreading area increases further, and all than CsF-RbF-AlF3The reason that brazing flux (seeing Fig. 2, Fig. 4) spreading area is big.
With in the course of reaction of steel, due to Ga2O3Interpolation, the P(phosphorus in " have activated " steel) element participate in reaction.By
GB/T 700-2006 " carbon structural steels " understands, P≤0.045(mass percent in Q235 steel)；By GB/T 20878-2007
" the stainless steel and refractory steel trade mark and chemical composition " understands, and 304(is equivalent to the trade mark 06Cr19Ni10 in new standard) rustless steel
P≤0.045(mass percent), but in two kinds of steel, the content of P is relative to Ga2O3If addition still exceed one times even
Dry times.But, due to Ga2O3" catalytic action " so that the P of trace has given play to the special role of " beyond the imagination ".React residual
AlPO in slag4、FePO4Appearance (seeing accompanying drawing 11), and have no that compound containing Cs, Rb, Ga occurs, on the one hand explanation occurs
" enrichment phenomenon " of P, on the other hand, illustrates that the compound of Cs, Rb, Ga is all in the state of " Dispersed precipitate ".
In view of the restriction of " sensitivity " of XRD analysis method, the diffraction maximum of the compound of generally below 1% is all difficult to differentiate
Out, but, this does not affect Ga2O3, CsF and RbF mechanism of action analysis with determine.
In view of the analysis of above-mentioned result of the test with to Ga2O3, the determination of CsF and RbF role, the present invention is the most excellent
Change and determine Ga2O3, the interpolation scope of CsF and RbF so that the brazing flux of the present invention has the most excellent performance.
