Workpiece is heated, and between temperature rises to 650 DEG C~700 DEG C, aluminium connection sheet can be in molten condition, aluminium connection sheet
A part can penetrate into high temeperature chemistry nickel dam, therewith fusion be bonded together；It is removed from the molds, obtains into after workpiece cooling
Product.
Formula and process advantage：
1st, the uniform covering power of thickness evenness thickness is well a big feature of chemical nickel plating, and the reason for be widely used it
One, chemical nickel plating avoids electrodeposited coating because CURRENT DISTRIBUTION is uneven and brought in uneven thickness；During chemical plating, as long as part
Surface and plating solution are contacted, and the composition consumed in plating solution can be supplemented in time, and the thickness of coating at plating piece position is substantially the same, i.e.,
It is also such to make groove, gap, blind hole；Really be because chemical nickel plating after red copper connection sheet surface it is still smooth, with aluminium
Its solder side is smooth during connection sheet progress hot pressing connects, significantly reduces the temperature rise in galvanization.
2nd, plating piece will not ooze hydrogen, without hydrogen embrittlement, dehydrogenation not needed after chemical nickel plating, while be also prevented from material and opened because of hydrogen embrittlement
Split.
3rd, function for example anti-corrosion, the high temperature oxidation resistance grade ratio electronickelling of many materials and parts is good.
4th, can be deposited on the surface of various materials, such as：Steel nickel-base alloy, zinc-containing alloy, copper alloy, aluminium, glass,
On the surface of the materials such as ceramics, plastics, semiconductor, so as to create condition to improve the performance of these materials.
5th, required direct current generator or control device need not typically be electroplated.
Compared with prior art, beneficial effects of the present invention are：One layer of high temeperature chemistry is plated on the surface of red copper connection sheet
Nickel dam, and aluminium connection sheet and high temeperature chemistry nickel dam are bonded together by high-frequency induction welder, the tightness degree that it is bonded is big
Big lifting, the temperature rise of connection substantially reduce, and process obtained workpiece stretch-proof by this technique and anti-seismic performance is able to greatly
Raising.
