Definitions

  • the invention relates to an insoluble anode for electroplating.
  • Galvanic processes such as copper plating, nickel plating, galvanizing or tinning, are operated by means of soluble or insoluble anodes.
  • soluble anodes which are also referred to as an active anode system
  • the anode changes into solution during the electrolysis.
  • insoluble anodes also referred to as inert anode systems
  • insoluble anodes consist of a carrier material on the one hand and a coating applied thereto, which can be referred to as an active layer, on the other hand.
  • Titanium, niobium or other reaction carrier metals are usually used as the carrier material, but in any case those materials which passivate under the electrolysis conditions.
  • As material for the active layer are usually electron-conducting materials, such as platinum, iridium or other precious metals, their mixed oxides or compounds of these elements are used.
  • the active layer can either be directly on the surface of the Carrier material may be applied or located on a distance to the substrate arranged substrate. Among others, such materials may be used as substrate, which may be considered as support material, for example titanium, niobium or the like.
  • additives which, for example, act as brighteners, increase the hardness and / or increase the scattering.
  • organic compounds are preferably used as additives.
  • gases such as oxygen or chlorine are formed at the insoluble anode. These gases can cause the additives contained in the electroplating bath to oxidize, which can lead to partial or even complete degradation of these additives. This circumstance weighs twice as hard. On the one hand, the additives must be replaced continuously, on the other hand disrupt the degradation products of the additives, so that it is necessary to renew the plating baths more often or clean or regenerate, which is uneconomical and beyond also ecologically meaningful.
  • anode for electroplating which has an anode base body and a Shielding, wherein the anode base body comprises a support material and a substrate having an active layer, the shield is spaced from the anode base attached thereto and reduces the mass transfer to the anode base body and away from it.
  • Such an anode allows in contrast to the embodiment of the EP 1 102 875 B1 a reduction in the expenditure on equipment and also has the advantage that the additives contained in the electroplating bath oxidize less strongly.
  • the anode base body of the anode is formed in two parts, which makes their production very expensive and therefore expensive.
  • the anode base body consists of a carrier material on the one hand and an active layer on the other hand, wherein preferably titanium is used as carrier material.
  • Suitable materials for the active layer are, in particular, platinum, iridium, mixed oxides of platinum metals or diamonds. Also for this reason, the proves out of the DE 102 61 493 A1 Prior art anode as relatively expensive, which is why the economics of operated using such an anode galvanic process in question. There is a need for improvement.
  • the invention proposes an insoluble anode for electroplating, which is formed in two or more phases and an anode base body on the one hand and a shield on the other hand, wherein the anode base body is integrally formed and made of steel, stainless steel or nickel ,
  • the anode according to the invention is formed in two or more phases and consists of an anode base body on the one hand and a shield on the other hand.
  • the anode body is different from that of the DE 102 61 493 A1 previously known anode is not in two parts, that is, from a substrate and formed an active layer consisting, but rather in one piece and consists of steel, stainless steel or nickel.
  • the anode according to the invention advantageously proves to be much less expensive to manufacture, allowing a more economical operation, especially with alkaline zinc and zinc alloy baths.
  • the anode according to the invention is suitable for electrolytes which work with inert anodes, for example also for high-speed systems, as well as for electrolytes with divalent tin or other easily oxidizing components.
  • the particular advantage of the anode according to the invention is that present in the electrolyte components or additives less or not oxidize, in the case of divalent tin, the disturbing oxidation of tin (II) to tin (IV) is prevented.
  • two-phase or multi-phase anode is understood to mean an anode which consists of an anode base body on the one hand and a shield for the anode base body on the other hand.
  • the anode base body represents the first phase and the shielding represents the second phase.
  • the shield of the anode is preferably arranged at a distance from the anode base body and consists of a non-conductive material, plastic or metal.
  • the shield is preferably formed in the manner of a fabric, mesh, mesh or the like.
  • the shield consists of a grid or mesh made of titanium.
  • the shield is made by a polypropylene existing tissue formed. Preference is given to the use of a two-part shield, wherein the first part of the shield is formed of a mesh or mesh made of titanium, whereas the second part of the shield is a fabric made of polypropylene.
  • the existing polypropylene fabric between the anode base body on the one hand and the grid made of titanium mesh or network on the other hand is arranged.
  • An anode with a two-part shield is three-phase.
  • the two-phase or multi-phase electrode system prevents too high a contamination of the electrolyte with oxygen and thus too high an additive consumption.
  • a galvanic bath operated with the anode according to the invention proves to be particularly economical.
  • the invention further proposes a method of electroplating in which an anode according to the above-described features is used.
  • the deposition is preferably by means of direct current. In this way, a particularly fine crystal structure can be achieved, which leads to improved physical properties of the deposited layer.
  • the process can be used in both horizontal and vertical systems.
  • the deposition can also be done by means of pulse current or pulse-reverse current.
  • the invention further proposes a galvanic bath, in particular an alkaline galvanic bath, with an anode according to the aforementioned features.
  • a galvanic bath in particular an alkaline galvanic bath
  • an anode according to the aforementioned features.
  • electroplating baths are alkaline zinc and zinc alloy baths, gold baths, silver baths, tin baths, tin alloy baths and bronze baths.
  • Fig. 1 shows a schematic representation of an anode 1 according to the invention in a partially sectioned side view.
  • the anode 1 is plate-shaped and has an anode base body 2 and a shield. 3
  • the shield 3 is arranged at a distance from the anode base body, wherein the distance between the anode base body 2 and shield 3 is referred to as "A".
  • the distance A between anode base body 2 and shield 3 can be 0.01 mm to 100 mm, preferably 0.05 mm to 50 mm, particularly preferably 0.5 mm to 10 mm.
  • the shield 3 is formed in two parts. It consists of a polypropylene fabric 4 on the one hand and a platinum metal fabric 5 on the other.
  • Fig. 1 reveals, the polypropylene fabric 4 between the anode base body 2 on the one hand and the metal fabric 5 on the other hand arranged.
  • the metal fabric 5 may be electrically conductively connected to the anode base body 2, which is not shown in FIG. 1 for the sake of clarity.
  • the anode 1 shown in Fig. 1 is three-phase.
  • a first phase provides the anode base 2 ready.
  • the second and third phases result from the shield 3, wherein the second phase is caused by the polypropylene fabric 4 and the third phase by the metal fabric 5.
  • the shield 3 is arranged only on one side of the anode base body 2. It goes without saying that a shield 3 can also be arranged on the other side, that is to say with reference to the sheet plane according to FIG. 1 on the left-hand side of the anode main body 2.
  • Fig. 2 shows in a schematic sectional view from above another embodiment of the anode 1 according to the invention.
  • the anode 1 of Fig. 2 is in correspondence of the embodiment of FIG. 1 also of an anode base body 2 and a shield 3.
  • the anode 1 of FIG. 2 is not plate-shaped, but formed with respect to its cross-section circular in the manner of a rod.
  • the shield 3 surrounds the anode main body 2 completely in the manner of a shell.
  • the shield 3 according to the embodiment of FIG. 2 is single-phase and consists for example of a metal mesh or a plastic fabric.
  • the distance A between anode base body 2 and shield 3 corresponds to the distance A according to the embodiment of FIG. 1.
  • the anode base body 2 is formed in one piece. It is made of steel, stainless steel or nickel.
