Abstract

PURPOSE:To obtain a conductor roll for supplying electric current with remarkably improved corrosion resistance, by plating a conductor roll for supplying electric current with Ni or an Ni-P alloy and by further plating it with an Ni-W alloy. CONSTITUTION:A conductor roll for supplying electric current is made of iron or an iron alloy plated optionally with a Cu alloy. An Ni or Ni-P alloy layer is formed on the peripheral surface of the roll. In order to form the layer, the roll is masked with a coating agent such as vinyl chloride resin paint except the peripheral surface, the surface is successively pretreated by degreasing, acid treatment and washing as usual, and the pretreated peripheral surface is chemically plated with the Ni-P alloy. The Ni-P alloy layer is then plated with an Ni-W alloy by a conventional method to form an Ni-W alloy layer consisting of 60-80wt% Ni and 40-20wt% W.

The energizing conductor is made of electric metal +, for example, zinc metal +, tin metal +, alloy metal +, composite metal +, etc.
When manufacturing surface-treated steel sheets, this is a member that conducts electrolysis using the steel sheet material as a cathode. Therefore, the current-carrying conductor is subject to mechanical wear due to constant contact with the steel plate and slippage occurring during such contact, and in particular, the portion that contacts the edge of the steel plate is subject to significant wear. In addition, contact with the liquid is unavoidable, and particularly in the case of acidic baths, the mechanical wear described above is significantly accelerated.

The material of the current-carrying conductor D-ru is made of iron or an iron base metal, or it is coated with copper or a copper alloy to improve conductivity. Because of this, it is used with a hardness of 0 mm. However, although the contactor D-R for current-carrying with a hardness of 0 mm has sufficient hardness and there is no problem with wear resistance, it is insufficient in terms of corrosion resistance. Lines and the like have the disadvantage that they are easily corroded because they are acidic baths. In particular, in the case of baths containing halogens, when the current-carrying conductor D-ru is made of hard chrome metal, it is fatal that it quickly erodes even with almost no mechanical friction. There are drawbacks. Furthermore, in recent years, METS+ has been diversified to meet various uses, such as various alloy METS+, multilayer METS+, and composite METS+.
etc. are being put into practical use, but in these applications, there is a demand for current-carrying tars with particularly excellent corrosion resistance.

It has been completed.
