Definitions
- This invention relates to an electrode for electroplating and a process for producing the same. More particularly, it relates to an electrode having excellent durability as an anode for continuous plating of a steel plate which is conducted at a high current density, and a process for producing such an electrode.
- a demand for surface-treated steel sheeting has recently been increasing in various fields, such as automobiles and appliances. With this demand, the electroplating technique used for continuously coating the surface of a steel band has become increasingly important.
- JP-B-53-18167 the term “JP-B” as used herein means an “examined published Japanese patent application”
- JP-A-56-47597 the term “JP-A” as used herein means an "unexamined published Japanese patent application”
- an insoluble electrode in electroplating is expected to bring about various advantages, such as (1) a possibility of plating with various alloys, (2) improvement of productivity by increasing anode current density and increasing line speed, (3) improvement of quality by leveling current distribution, and (4) reduction in frequency of anode exchange.
- insoluble electrodes include lead electrodes, lead alloy electrodes, and platinum-plated electrodes.
- lead or lead alloy electrodes to be used for lead or lead alloy electroplating have insufficient insolubility, so that lead is gradually dissolved out, resulting in deterioration of plated product quality or formation of a large quantity of sludge. It is therefore necessary to use a large amount of an adsorbent for removing the dissolved lead ion.
- platinum coating of platinum-plated electrodes easily falls off upon use at a high current density, making the electrode useless in a short time.
- An object of this invention is to provide an insoluble electrode for electroplating which is free from the above-described disadvantages associated with conventional insoluble electrodes for electroplating, that is, which has sufficient durability even when used at a high current density.
- Another object of this invention is to provide a process for producing the above-described insoluble electrode for electroplating.
- the present invention provides an insoluble electrode for electroplating comprising a base having coated thereon an electrode active substance containing a platinum metal or an oxide thereof, said base comprising an anticorrosion-metal plate having joined thereon a porous anticorrosion-metal sheet.
- the base of the electrode according to the present invention comprises an anticorrosion-metal plate having joined thereon a porous anticorrosion-metal sheet.
- the anticorrosion-metal which can be used in the present invention is not particularly limited in kind, as long as it is usable as an electrode base. Suitable anticorrosion-metals include Ti, Ta, Nb, Zr, and alloys thereof, in view of their excellent anticorrosion properties and sufficient mechanical strength.
- the material of the porous anticorrosion metal sheet and that of the metal plate are usually the same, but may be different.
- the metal plate which is usually a non-porous flat plate but may be a curved plate, should have a sufficient thickness to maintain mechanical strength of the electrode and for electricity to sufficiently pass.
- the porous metal sheet which is joined to the metal plate functions to permit a large quantity of a gas evolved from the anode, such as oxygen, to escape, thereby preventing retention of bubbles.
- the porous metal sheet also functions to greatly increase the electrode surface area, to thereby reduce electrolytic voltage.
- Suitable porous metal sheets providing this effect include expanded metal, punched metal, wire sheet, and wire cord fabric, each having a porosity of from 5 to 90%.
- Metallic fiber laminated sheets, metallic fiber cloth, wire rolls, metallic felt, and porous sintered bodies of metals are also employable. If desired, taking strength and electricity quantity into consideration, a plurality of such porous sheets may be laminated.
- joining of the metal plate and the porous sheet is carried out by bolting, welding, or like technique. Taking it into consideration that a large electric current passes through the joining area, a welded joint having a small electrical resistance is preferred. An increase in electrolytic voltage and heat generation can be suppressed by forming a sufficient number or amount of welded joining area.
- the above-described base comprising the metal plate having joined thereon the porous metal sheet is then coated with an electrode active substance.
- the base Prior to coating, the base can be subjected to a surface treatment, such as nitriding treatment, boriding treatment, or carbonization treatment, to further improve anticorrosion properties.
- an intermediate layer comprising a conductive oxide containing an oxide of at least one metal selected from the group consisting of Ti, Zr, Nb, Sn, Sb, and Ta may be provided on the base.
- Such an intermediate layer can be formed by various means, such as those employable for coating of an electrode active substance on the base as hereinafter described.
- a pyrolysis method comprising applying a solution of a salt of the metallic component for the intermediate layer onto the base and calcining the salt to form an oxide layer is preferred.
- Electrode active substances containing a platinum metal or an oxide thereof exhibit excellent electrochemical characteristics and chemical resistance for use in insoluble electrodes for electroplating.
- suitable electrode active substances include at least one platinum metal, e.g., Ru, Rh, Pd, Ir, and Pt, platinum metal alloys, and platinum metal oxides.
- Composite substances comprising such a platinum metal, alloy or oxide and at least one of base metals, e.g., Ti, Zr, Nb, Ta, and Sn, or an oxide thereof may also be used. This being the case, the content of the platinum metal component in the composite substance is preferably 10% by weight or more, based on the elemental platinum content, to ensure satisfactory electrode activity.
- Methods for coating the electrode active substance on the base are not particularly restricted, and include various known methods for electrode coating, such as those described in JP-B-48-3954.
- a suitable method is a pyrolysis method in which a solution of the above-described electrode active substance metallic component or a salt thereof in an appropriate solvent is applied to the base by coating or dipping, and then calcined by heating in an oxidative, neutral or reductive atmosphere to form a coating layer. If desired, the coating procedure can be repeated to obtain a desired coating thickness.
- the thus produced electrode of the present invention when used for continuous plating on a steel plate, etc., exhibits higher anticorrosion and electrode activity than conventional insoluble electrodes, even at a high current density. Hence, it withstands use in various corrosive electrolytic solutions, thereby enjoying various advantages accompanying use of an insoluble electrode as set forth above.
- the electrode of the present invention has a composite structure in which a porous metal sheet is joined to a metal plate, it is possible to pass a higher electric current as compared with smooth plate electrodes, and bubbles generated on the electrode can satisfactorily escape. Further, since the bubbles, if any remains on the electrode, have a small thickness, an increase in electrolytic voltage due to resistance of the bubbles can be inhibited. Thus, the electrode of the invention brings about marked improvements in productivity of a plated steel plate and economy due to increased line speed, saving of electric power, and the like.
- the insoluble electrode according to the present invention is also applicable to other organic or inorganic electrolysis, surface treatment of metals, electrolytic winning, and the like.
- An expanded metal sheet made of pure titanium having a thickness of 0.1 mm, 0.3 mm, or 0.5 mm and a porosity of 50% was joined by welding to a commercially available titanium plate having a size of 100 mm x 100 mm x 5 mm (t) to prepare three kinds of bases. After degreasing with acetone, each base was washed successively with a pure oxalic acid solution and pure water, and then dried.
- a butanol solution containing iridium chloride and tantalum chloride at a molar ratio of 6/4 was coated on each of the bases with a brush, dried, and calcined in air at 550°C to prepare an electrode. The coating, drying and calcination operations were repeated until the iridium content in the coat reached 0.3 mg/cm2.
- Electrolysis was carried out in a model zinc plating bath described below in a non-mobile phase, using each of the resulting electrodes as an anode and mild steel sheet as a cathode, and the electrolytic voltage (bath voltage) was measured.
- Model Zinc Plating Bath Na2SO4: 100 g/l (NH4)2SO4: 100 g/l pH: 1.2 Temperature: 60°C Current Density: 200 A/cm2
- electrolysis was carried out in a 1M sulfuric acid aqueous solution at a current density of 2 A/cm2 using the electrode as an anode and a platinum plate as a cathode.
- the time required for the bath voltage to reach 10 V was taken as durability.
- a punched metal sheet made of titanium having a thickness of 0.5 mm, a pore diameter of 2 mm, and a porosity of 50% was joined to a titanium plate or a Ti-3Ta alloy (Ti-based alloy containing 3 wt% Ta, hereinafter the same) plate to prepare a Ti or Ti-3Ta base (Samples 1 and 3).
- An intermediate layer of a metallic oxide shown in Table 2 below was formed on a Ti or Ti-3Ta sheet to a thickness of 3 ⁇ m to prepare a Ti or Ti-3Ta base (Samples 2 and 4).
- An electrode active substance shown in Table 2 was coated on each of the bases to a thickness of 0.3 mg-Pt/cm2 to prepare an electrode, and durability of the resulting electrode was evaluated in the same manner as in Example 1.
- Electrodes were prepared in the same manner as for Samples 1 to 5, except that the base had no punched metal sheet, and evaluated in the same manner as in Example 1.
- the insoluble electrode for electroplating which comprises an anticorrosion-metal composite plate base having coated thereon an electrode active substance containing a platinum metal or an oxide thereof, exhibits excellent durability and makes it possible to reduce electrolytic voltage. Because of the composite structure of the base comprising a basic metal plate having joined thereon a porous metal sheet, the electrode permits operations at high current density and prevents an increase in voltage due to evolution of gases, thereby greatly improving productivity and saving electric power in electroplating.
- the durability of the electrode can be further enhanced by treating the surface of the base by nitriding, boriding, or carbonizing, or by providing an intermediate layer comprising a conductive oxide on the surface of the base.
