Description
Technical field
The present invention relates to a kind of hot-dip aluminizing technique of the energy-saving anti-corrosion gold utensil of overhead transmission line, belong to gold utensil surface treatment
Technical field.
Background technology
Transmission line of electricity voltage etc. is higher, higher to the quality requirement of electric armour clamp.Except needing to meet higher machinery by force
Outside degree and more preferable decay resistance, high request is it is also proposed to anticorona.Existing common hot dip galvanizing process can not be met
Ultra-high-tension power transmission line assorted golden tool, particularly steel connection gold utensil, metal parts of pull wire, stockbridge damper etc. it is corrosion-resistant and heat resistance
It is required that, and zinc resource is very deficient in China.Accordingly, it would be desirable to research and develop very necessary using novel process.
Application of the ultrasonic wave in terms of electroplating technology had correlation report, such as ultrasonic electroplating tin alloy technical study,
The research of ultrasonic electroplating tin alloy, the tin plating technology of ultrasonic fast electric.Ultrasonic wave plays the role of following several respects in plating：
1）Promote the whipping process in electrodeposition process electroplating process, such as Stirring, circulate mechanical agitation and people
Work stirring etc. can only all reduce the effective thickness of diffusion layer near negative electrode to a certain extent.When ul-trasonic irradiation in plating solution with
Afterwards, ultrasonic cavitation and effect of vibration make equivalent to a strong stirring action of exception, this effect is applied with to plating solution
The effective thickness of cathode diffusion layer reduces rapidly, and the concentration of metal ions increase of electrode surface, deposition velocity is accelerated.Also exactly
Due to reducing concentration polarization, allow to use higher working current density in electroplating in ultrasonic field, so that operating current is close
Degree scope broadens, and the operating condition of plating is improved.In addition, the microjet of ultrasonic wave also enhances the diffusion mass transfer mistake of plating solution
Journey, is greatly improved the bath system electrodeposition rate by diffusion control.
2）Improve quality of coating：In electroplating process, ultrasonic cavitation can make hydrogen enter cavitation bubble or as cavitation
Core, is conducive to the precipitation of hydrogen.Meanwhile, the sound blaster that ultrasonic cavitation is produced constantly cleans electrode surface, is conducive to driving away
The bubble of aggregation at the electrode surface, so as to reduce the hole of coating, reduces the hydrogen embrittlement that coating is produced by liberation of hydrogen, reduces
The internal stress of coating, adds the compactness of coating, improves quality of coating.
3）Promote the scattered of micro-nano granules and deposit：In the preparation process of micro-nano composite deposite, ultrasonic wave is to molten
The dispersed with stirring effect of micro-nano granules has exceeded well over the severe degree that mechanical agitation can reach in liquid, and this disperses to particulate
Effect is especially apparent.The sound wave that ultrasonic wave is produced can be such that the particulate of suspension is in the solution macroscopically being uniformly distributed, and cavitation is imitated
High pressure shock wave and strong Random Oscillation that should be produced can crush the population of reunion shape, make particulate further disperseed and
Homogenization, improves the dispersiveness of particulate in the plating solution.
In addition, some surfactants are commonly incorporated into the electro-deposition of composite deposite makes charge particles, ultrasound cavitation effect
Can clean up absorption originally with the microjet produced in transonic process, in the gas and impurity of microparticle surfaces, improves
The wetting conditions of particulate and plating solution, make it easier to adsorb powered surface active agent ion, so that particulate is on negative electrode
Deposition increases, and promotes the co-deposition of particulate and metal ion, advantageously forms uniform, fine and close and smooth composite deposite.
Ultrasonic assistant electroplating technology is one of research frontier of sonochemistry and electrochemistry subject crossing, but at present
Also the report that gold utensil surface is aluminized is not used for it on ultrasonic assistant, if it is possible to which ultrasonic technology is applied to gold utensil hot dip
In aluminium, it will promote the progress of industry significantly.
