Definitions

  • the present invention relates to the use of a treatment solution for treating the surface of a steel sheet coated with a metal coating based on zinc or its alloys. It also relates to a method of lubricating such a coated sheet.
  • the very high friction exerted by the forming tools on the surface of the sheet causes, on the surface of the sheet, powder or particles based on zinc or its alloys generated by the degradation of the coating.
  • the accumulation and / or agglomeration of these particles or powder in the forming tools can cause damage to the formed parts, by formation of pins and / or strictions.
  • the sheet may break in the event of insufficient sliding of the sheet into the surface. grip of the formatting tool. These breaks can occur, even by applying a film of oil with a sufficient grammage to the surface of the sheet, ie greater than 1 g / m 2 , because it is not possible to keep a distribution on the surface of the sheet. homogeneous oil film. This is due to the dewetting phenomenon which corresponds to the presence of areas with an oil deficit.
  • the oil deficits in certain areas of the oil film due to the dewetting phenomenon are also responsible for a less temporary protection against corrosion of the steel sheet during storage.
  • the present invention therefore aims to provide a treatment solution which, applied to the surface of a steel sheet coated with a metal layer based on zinc or its alloys, reduces the degradation of the galvanized surface of this sheet during its shaping, reduce the amount of lubricating oil to be deposited on the sheet before shaping, and improve the temporary protection against corrosion of the sheet.
  • the subject of the invention is the use of an aqueous treatment solution containing sulphate ions SO 4 2- at a concentration greater than or equal to 0.01 mol / l, for treating the surface of a sheet coated steel on at least one of its faces, a metal coating based on zinc or its alloys, to reduce the formation of powder or metal particles based on zinc or its alloys generated by degradation coating during the shaping of said sheet.
  • metal coating based on zinc alloy a zinc coating comprising one or more alloying elements, such as for example and without limitation, iron, aluminum, silicon, magnesium, and nickel.
  • the treatment solution is conventionally applied, for example by dipping, by spraying or by coating, as well on electrogalvanized sheets as on dip galvanized sheets.
  • the aqueous treatment solution additionally contains Zn 2+ ions at a concentration greater than or equal to 0.01 mol / l, which make it possible to obtain a more homogeneous deposition.
  • the solution of treatment by dissolution of zinc sulphate in pure water is prepared; for example, zinc sulfate heptahydrate (ZnSO 4 , 7H 2 O) is used; the concentration of Zn 2+ ions is then equal to that of the SO 4 2- anions.
  • ZnSO 4 , 7H 2 O zinc sulfate heptahydrate
  • the pH of the treatment solution preferably corresponds to the natural pH of the solution, without addition of base or acid; the value of this pH is generally between 5 and 7.

  • the treatment solution used contains between 20 and 160 g / l of zinc sulphate heptahydrate, corresponding to a concentration of Zn 2+ ions and a concentration of SO 4 2- ions of between 0.07 and 0.55 mol. / l. Indeed, it was found that in this range of concentrations, the deposition rate was little influenced by the value of the concentration.
  • the treatment solution is applied under conditions of temperature, time of contact with the galvanized surface, and of concentrations of SO 4 2- ions and Zn 2+ ions adjusted to form a layer based on hydroxysulfate and sulfate having a sulfur content of between 3.7 and 27 mg / m 2 .
  • the treatment solution contains an oxidizing agent for zinc, such as hydrogen peroxide.
  • This oxidizing agent can have a very marked hydroxysulfation and sulphation accelerator effect at low concentration. It was found that the addition of only 0.03%, ie 8.10 -3 mol / liter of hydrogen peroxide, or 2.10 -4 mol / liter of potassium permanganate in the solution allowed to double (approximately) the speed of deposit. It has been found, on the contrary, that concentrations 100 times higher no longer made it possible to obtain this improvement in the deposition rate.
  • the layer deposited on the sheet is adherent; Drying is adjusted to remove residual liquid water from the deposit.
  • the sheet is preferably rinsed so as to eliminate the soluble part of the deposit obtained; the absence of rinsing and the obtaining of a partially water-soluble deposit resulting therefrom are not very detrimental to the reduction of the degradation of the galvanized coating during the shaping of the sheet, as long as the obtained deposit includes a layer based on zinc hydroxysulfate and zinc sulfate insoluble in water in contact with the sheet.
  • the aqueous treatment solution comprising a concentration of SO 4 2- ions greater than or equal to 0.01 mol / l is applied under anodic polarization, and the pH of the treatment solution is greater than or equal to 12, and less than 13.

  • the concentration of sulphate ions is preferably less than or equal to 1 mol / liter; in the case of the use of sodium sulphate, at concentrations greater than 142 g / l (equivalent to 1 mol SO 4 2- / liter), for example 180 g / l, there is a decrease in the formation yield of the layer based on zinc hydroxysulfate and zinc sulfate.
  • the total quantity of hydroxysulfates and sulphates deposited should be greater than or equal to 0.5 mg / m 2 and less than or equal to 30 mg / m 2 in equivalent sulfur, preferably between 3.5 and 27 mg / m 2 sulfur equivalent.
  • the zinc required for the formation of the zinc hydroxysulfate and zinc sulphate deposit results from the anodic dissolution of the zinc under the effect of the polarization of the galvanized surface.
  • the density of electrical charges, circulating during the treatment through the surface of the sheet be adjusted so as to form a layer based on zinc hydroxysulfate and zinc sulphate, the sulfur content is greater or equal to 0.5 mg / m 2 .
  • the charge density applied is preferably between 10 and 100 C / dm 2 of surface to be treated.
  • the layer based on zinc hydroxysulfate and zinc sulphate at a high polarization current density, in particular greater than 20 A / dm 2 and, for example 200 A / dm 2 .
  • the deposition efficiency is very low and the amount of sulfur in the deposited layer does not make it possible to obtain a significant reduction in the degradation of the zinc coating of the sheet metal. when formatting.
  • the temperature of the treatment solution is generally between 20 ° C and 60 ° C. Preferably, a temperature greater than or equal to 40 ° C. is used, so as to increase the conductivity of the solution and to reduce the ohmic losses.
  • the speed of circulation of the solution at the surface of the sheet does not have a decisive impact on the treatment according to the invention.
  • the treated surface is thoroughly rinsed with deionized water. This rinsing step is important for removing alkaline reagents from the deposition surface, which would cause corrosion problems.
  • the lubricating oil film is applied with a grammage of preferably less than 0.9 g / m 2 , and more preferably between 0.2 and 0.5 g / m 2 , because these weights are sufficient to obtain excellent protection. temporary protection against corrosion and avoid any risk of pollution of the workshops and the tools of formatting.
