Title:
支持バーに電流取得部を配設する方法および支持バー
Document Type and Number:
Japanese Patent JP2011526650
Kind Code:
A
Abstract:
The invention relates to a method of providing an electric current taker made from silver and having a highly electroconductive contact surface into an aluminium support bar to be used in electrolysis. In order for the support bar and the electric current taker therein to be easily, quickly and inexpensively manufactured, the method comprises a) heating a first end of the support bar and providing on top of it a solder containing a substance whose affinity to oxygen is high after a temperature of an aluminium surface is at a temperature which exceeds a melting temperature of the solder, whereby the solder is spread in a molten state on top of the surface, b) breaking an aluminium oxide layer between the aluminium and the molten solder by a mechanical treatment so that oxygen is released from the aluminium oxide layer, the oxygen reacting with the substance of the solder having a high affinity to oxygen and forming, together with the substance, on the surface of the molten solder an oxide layer, and c) providing, on top of the solder, the electric current taker and letting the solder to solidify and the electric current taker to become attached to the solidified solder. The invention further relates to a support bar.
