Description
Technical field
The present invention relates to welding technology fields, and in particular to a kind of for the aqueous of paste XHBNi-5 nickel-based solders preparation
Into lotion.
Background technology
Nickel-based solder is because containing the intensified elements such as chromium, silicon, boron, phosphorus, and solder embrittlement is big, and forming ability is very poor, generally with
Pulverulence is supplied, however for the welding of the special constructions part such as cellular, large area, powdered solder is brought such as
The shortcomings that operating procedures such as addition is inconvenient, additive amount is difficult to grasp.Therefore, during the use of nickel-based solder, often by it
Paste solder is made and is applied with appropriate mixed into lotion.In addition, with the degree of automation of soldering tech in recent years
It is continuously improved, paste solder is gradually taken seriously when having many advantages, such as high service efficiency, assembling easy to automate.Into cream
Body is core component prepared by paste solder as the important component that nickel-based solder is separately made to paste solder.
It is claimed below to being used for having into lotion for nickel-based solder powder：Paste solder is mixed and made into nickel-based solder powder
Afterwards, paste solder has good storage stability, is not settled in Storage period, is not stratified, do not reunited；Paste solder has suitable
Viscosity；The oxidation of nickel-based solder can be reduced in Storage period；Carbon-free residual after paste solder soldering.In addition, for XHBNi-5
The characteristics of nickel-based solder, to there is additional requirement into lotion.XHBNi-5 (NiCr29P6Si4) is a kind of new nickel-based solder, phase
Comparison BNi-5 has the characteristics that low brazing temperature, brazed seam good corrosion resistance, mobility and joint filling are good, at present in multiple fields
Progressively substituting BNi-5 as brazing material.Vacuum brazing is carried out since XHBNi-5 nickel-based solders powder is formed with powder
When, (vacuum degree is not less than 1 × 10 in high vacuum conditions-2Pa the oxide of a large amount of nickel, chromium) still can be formed, soldering is caused to be lost
It loses, is not only simple carrier for the effect of XHBNi-5 nickel-based solder powders into lotion therefore, and must have in high temperature
The effect of nickel-based solder oxidation is reduced after vacuum brazing.
