Definitions

  • This invention relates to a method for electroplating an uncoated steel strip with a plating layer and an improvement thereof.
  • a cold-rolled steel strip is provided which is usually annealed after cold-rolling to soften the steel by recrystallisation annealing or recovery annealing. After the annealing and before plating the steel strip is first cleaned for removing oil and other surface contaminants. After the cleaning step, the steel strip is pickled in a sulphuric or hydrochloric acid solution for removing the oxide film. Between different treatment steps the steel strip is always rinsed with deionised water to prevent contamination of the solution used for the next treatment step with solution of the preceding treatment step. Consequently the steel strip is thoroughly rinsed after the pickling step. During rinsing and transport of the steel strip to the plating section a fresh thin oxide layer is formed instantly on the bare steel surface and needs to be protected quickly.
  • the part to be plated (the steel strip) is the cathode of the circuit.
  • the anode of the circuit may be made of the metal to be plated on the part (dissolving anode, such as those used in conventional tinplating) or a dimensionally stable anode (which does not dissolve during plating).
  • the anode and cathode are immersed in an electrolyte solution containing ions of the metal to be deposited onto the blackplate substrate.
  • Blackplate is a tin mill product which has not (yet) received any metallic coating during production. It is the basic material for the production of other tin mill products. Blackplate can be single reduced (SR) full-hard or annealed (recovery annealed or recrystallisation annealed) or double reduced (DR) in which case it has been subjected to a second cold rolling reduction after annealing.
  • the SR or DR blackplate is usually provided in the form of a coiled strip and is the uncoated starting material for the coating process according to the invention.
  • Figure 1 schematically summarises the process steps to obtain the coated product, starting from a hot-rolled strip. Before cold-rolling, the hot-rolled strip is usually pickled (not shown) to remove the hot-rolling scale and cleaned (not shown) to remove any contaminants from the strip.
  • the coated product performs just as well in terms of corrosion performance, coatability, adherence of the lacquer coating or polymer coating to the coated product and the can-making performance of the coated product, no adverse effects have been observed of the presence of the stripes, the stripy appearance is considered to be visually less appealing and therefore undesired.
  • the object is reached with a method for manufacturing a chromium metal - chromium oxide coated blackplate by electrolytically depositing the chromium metal - chromium oxide coating on blackplate in a continuous high speed plating line operating at a line speed of at least 50 m/min from an electrolyte solution comprising a trivalent chromium compound, wherein the electrolyte solution is free of chloride ions and free of a boric acid buffering agent, the electrically conductive substrate acts as a cathode and an anode comprising a catalytic coating of iridium oxide or a mixed metal oxide for reducing or eliminating the oxidation of Cr 3+ -ions to Cr 6+ -ions, wherein the electrolyte solution contains at most 250 mM Cr 3+ -ions, a complexing agent at a (complexing agent/Cr 3+ ) molar ratio of at least 1:1, 0 to 2800 mM of sodium sulphate (Na 2 SO 4
  • the process according to the invention is equally applicable to provide a chromium metal-chromium oxide coating on other metal substrates such as nickel plated steel strip.
  • sulphuric acid or sodium hydroxide may be added to adjust the pH to a value inside the desired range.
  • acids or bases may be used, but in view of the bath chemistry sulphuric acid and sodium hydroxide are preferable.
  • any steel grade suitable for producing packaging steel may be used.
  • a stripy appearance of a deposited surface is usually associated with a certain inhomogeneity in the electroplating process.
  • a local difference in coverage or local differences in the composition of the coating layer may be the cause of the stripy appearance. It would be obvious to the skilled person to attempt to solve this problem by increasing the amount of deposited material by either increasing the amount of metal ions in the electrolyte, or by increasing the current density.
  • the inventors found that by increasing the chromium(III) content in the electrolyte, the appearance of the coated strip worsened, and that the stripy appearance persisted. Surprisingly and counter-intuitively the inventors found that decreasing the amount of metal ions in the electrolyte resulted in a decrease in the stripy surface and that the surface becomes even and shiny when the coating was deposited in accordance with the process of the invention.
  • the complexing agent is formate (HCOO - ), added to the electrolyte solution preferably as sodiumformate (HCOONa).
  • HCOONa sodiumformate
  • complexing agents that can be used instead of formate, or in addition thereto are oxalate-ions, and acetate-ions.
  • the Cr 3+ -ions are provided by a water soluble chromium(III) salt and wherein the water soluble chromium(III) salt preferably is one or more of the following water soluble chromium(III) salts:
  • the electrolyte solution contains at most 225 mM of Cr 3+ -ions and/or at least 100 mM of Cr 3+ -ions, preferably at least 125 mM of Cr 3+ -ions. This preferred range provides good results.
  • the pH of the electrolyte solution is at most 2.8, preferably at most 2.6 or 2.4, more preferably at most 2.2.
  • the lower pH results in a less efficient plating process, the surface quality is much improved in that it shows no stripes.
  • the formate/Cr 3+ molar ratio is at most 2.5:1.
  • the formate-ion is needed as a complexing agent and the ratio of at most 2.5:1 has proven to be sufficient in most cases.
  • the molar ratio is at most 2.0:1, even more preferably 1.75:1.
  • the molar ratio is at least 1.1:1, more preferably 1.25:1.
  • the electrolyte solution contains at least 75 mM and/or at most 600 mM of sodium formate.
  • at least 75 mM should be added, preferably at least 100 mM and even more preferably 200 mM.
  • the maximum is preferably at most 600 mM of sodium formate. If also chromium(III)formate is added to the electrolyte solution as the water soluble chromium salt then the formate added this way needs to be subtracted from the sodium formate additions as given herein above.
  • the values for sodium formate become at least 25 mM, preferably at least 50 mM and even more preferably 150 mM.
  • the maximum is preferably at most 550 mM of sodium formate.
  • the electrolyte solution contains at least 210 mM and/or at most 845 mM of sodium sulphate.
  • the plating temperature is at least 40 °C, preferably at least 50 °C, more preferably at least 55 °C.
  • the line speed of the plating line is at least 100 m/min, more prefebrably at least 200 m/min.
  • the coated blackplate is further coated on one or both sides by a film lamination step or a direct extrusion step, with an organic coating consisting of a thermoplastic single layer, or a thermoplastic multi-layer polymer, preferably wherein the thermoplastic polymer coating is a polymer coating system comprising one or more layers comprising thermoplastic resins such as polyesters or polyolefins, acrylic resins, polyamides, polyvinyl chloride, fluorocarbon resins, polycarbonates, styrene type resins, ABS resins, chlorinated polyethers, ionomers, urethane resins and functionalised polymers; and/or copolymers thereof; and or blends thereof.
  • thermoplastic resins such as polyesters or polyolefins, acrylic resins, polyamides, polyvinyl chloride, fluorocarbon resins, polycarbonates, styrene type resins, ABS resins, chlorinated polyethers, ionomers, urethane resins and functionalised
  • the blackplate provided with a chromium metal - chromium oxide coating obtained by the process according to the invention has a shiny coating is shiny and shows no stripy appearance.
  • the invention is also embodied in the use of the chromium metal - chromium oxide coated blackplate obtainable by the process according to the invention in a process to produce containers for packaging purposes.
  • An electrolyte was prepared having a sodium formate concentration of 20 g/l (294 mM), a sodium sulphate concentration of 80 g/l (563 mM) and a pH of 2.6, 2.15 and 2.0, and a chromium concentration of 10 g/l (192 mM).
  • the formate/Cr 3+ ratio 1.53.
  • the appearance is not stripy, with the better appearance being obtained with the lower pH-values. Stripe free and shiny surfaces were obtained at line speeds of 100 and 200 m/min or higher.
  • the deposition mechanism of the chromium layer from the electrolyte solution according to the invention is assumed to be based on a fast, stepwise deprotonation of the water ligands in the Cr 3+ -formate complex ion induced by a surface pH increase as a result of hydrogen evolution (2H + + 2e - ⁇ H 2 (g)) (See Figure 3 and 4 ): [Cr(HCOO)(H 2 O) 5 ] 2+ + OH - ⁇ [Cr(HCOO)(OH)(H 2 O) 4 ] + + H 2 O (regime I) [Cr(HCOO)(OH)(H 2 O) 4 ] + + OH - ⁇ Cr(HCOO)(OH) 2 (H 2 O) 3 ⁇ + H 2 O (regime II) Cr(HCOO)(OH) 2 (H 2 O) 3 ⁇ + OH - ⁇ [Cr(HCOO)(OH) 3 (H 2 O) 2 ] - + H 2
  • regime II See Figure 4
  • a mixed Cr-metal-carbide-oxide coating is deposited on the steel substrate.
  • regime III there is no deposition of chromium, and in regime III the amount of deposited chromium drops sharply.
  • the current density at which the desired chromium coating weight and composition are obtained depends on the electrolyte composition, pH, temperature and mass transfer rate (strip speed in case of a strip plating line).
  • the optimal current density is not a discrete value, but a range of values restricted by a lower and an upper limit. This current density range is called the 'plating window'. Within the plating window, the coating properties fall within certain specifications. From an operational perspective, a large plating window is desired, because this simplifies process control.
  • titanium anodes comprising a catalytic coating or mixed metal oxide of iridium oxide and tantalum oxide are chosen.
  • the substrate was a 0.183 mm thick cold rolled blackplate material and the dimensions of the cylinder were 113.3 mm x ⁇ 73 mm. The cylinders were cleaned and activated under the following conditions prior to plating.

  • the organic coating may be provided as a lacquer or as a thermoplastic polymer coating.
  • thermoplastic polymer coating is a polymer coating system that comprises one or more layers of thermoplastic resins such as polyesters or polyolefins, but can also include acrylic resins, polyamides, polyvinyl chloride, fluorocarbon resins, polycarbonates, styrene type resins, ABS resins, chlorinated polyethers, ionomers, urethane resins and functionalised polymers.

  • thermoplastic polymer coating systems have shown to provide excellent performance in can-making and use of the can, such as shelf-life.
  • the application process of the thermoplastic polymer coating is preferably performed by laminating a polymer film onto the coated blackplate by means of extrusion coating and lamination, wherein a polymer resin is melted and formed into thin hot film, which is coated onto the moving substrate.
  • the coated substrate then usually passes between a set of counter-rotating rolls, which press the coating onto the substrate to ensure complete contact and adhesion.
