Definitions

  • a film of lubricating oil is applied to its surface so as to facilitate the forming operation.
  • the oil deficiency in certain areas of the oil film due to the dewetting effect is also responsible for lesser temporary corrosion protection of the steel sheet while it is being stored.
  • the subject of the invention is the use of an aqueous treatment solution containing sulfate ions SO 4 2 ⁇ with a concentration of not less than 0.01 mol/l in order to treat the surface of a steel sheet treated on at least one of its sides with a metal coating based on zinc or its alloys, for the purpose of reducing the formation of metal powder or particles based on zinc or its alloys generated by the degradation of the coating while said sheet is being formed.
  • the use of a steel sheet coated with an almost pure zinc coating is preferred.
  • a layer forms on the surface of the sheet that is based on zinc hydroxysulfate and zinc sulfate and is both sufficiently thick and sufficiently adherent.
  • SO 4 2 ⁇ concentration is less than 0.01 mol/l, but it has also been found that too high a concentration does not substantially improve the rate of deposition and may even slightly reduce it.
  • the treatment solution is applied in a conventional manner, for example by dipping, by spraying or by coating, both on electrogalvanized sheet and on hot-dip galvanized sheet.
  • the conditions under which the treatment solution is applied to the surface of the sheet namely the temperature, the time during which the solution is in contact with the galvanized surface, the SO 4 2 ⁇ ion concentration and the Zn 2+ ion concentration, are adjusted so as to form a layer based on zinc hydroxysulfate and zinc sulfate, the sulfur content of which is not less than 0.5 mg/m 2 . This is because when the sulfur content is less than 0.5 mg/m 2 , the reduction in degradation of the coating is less substantial.
  • the time during which the treatment solution is in contact with the galvanized surface is between two seconds and two minutes and the temperature of the treatment solution is between 20 and 60° C.
  • the treatment solution used contains between 20 and 160 g/l of zinc sulfate heptahydrate, which corresponds to a Zn 2+ ion concentration and an SO 4 2 ⁇ ion concentration that lie between 0.07 and 0.55 mol/l.
  • zinc sulfate heptahydrate which corresponds to a Zn 2+ ion concentration and an SO 4 2 ⁇ ion concentration that lie between 0.07 and 0.55 mol/l.
  • the treatment solution contains an oxidizing agent for zinc, such as hydrogen peroxide.
  • This oxidizing agent may have a very pronounced sulfation/hydroxysulfation accelerator effect at low concentration. It has been found that the addition of only 0.03%, i.e. 8 ⁇ 10 ⁇ 3 mol/l of hydrogen peroxide, or of 2 ⁇ 10 ⁇ 4 mol/l of potassium permanganate, to the solution makes it possible for the rate of deposition to be doubled (approximately). However, it has been found that concentrations 100 times higher no longer allow this improvement in deposition rate to be obtained.
  • the layer deposited on the sheet is adherent.
  • the drying is adjusted in order to remove the residual liquid water from the deposit.
  • the aqueous treatment solution having an SO 4 2 ⁇ ion concentration of not less than 0.01 mol/l is applied under anodic polarization and the pH of the treatment solution is equal to 12 or higher, but less than 13.
  • the pH of the solution is less than 12, adherent hydroxysulfates are not formed on the surface to be treated. If the pH of the solution is equal to 13 or higher, the hydroxysulfate redissolves and/or decomposes into zinc hydroxides.
  • the thickness of the zinc hydroxysulfate/zinc sulfate-based layer deposited corresponds to more than 0.5 mg/m 2 of equivalent sulfur, preferably at least 3.5 mg/m 2 of equivalent sulfur.
  • the total deposited amount of hydroxysulfates and sulfates is not less than 0.5 mg/m 2 but not to exceed 30 mg/m 2 of equivalent sulfur, preferably to be between 3.5 and 27 mg/m 2 of equivalent sulfur.
  • the zinc needed to form the zinc hydroxysulfate/zinc sulfate-based deposit comes from the anodic dissolution of zinc under the effect of the polarization of the galvanized surface.
  • the applied charge density is preferably between 10 and 100 C/dm 2 of surface to be treated.
  • the zinc hydroxy-sulfate/zinc sulfate-based layer to be deposited under a high polarization current density, especially greater than 20 A/dm 2 , 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 significantly reduce the degradation of the zinc coating on the sheet while it is being formed.
  • the temperature of the treatment solution is generally between 20° C. and 60° C.
  • the treatment is carried out at a temperature of 40° C. or higher, so as to increase the conductivity of the solution and to reduce the ohmic losses.
  • the coated surface is thoroughly rinsed with demineralized water. This rinsing step is important in order to remove the alkaline reactants at the surface of the deposit, reactants that might cause corrosion problems.
  • the subject of the invention is also a method of lubricating a steel sheet coated with a layer consisting of a metal coating based on zinc or its alloys, in which method:
  • the weight of lubricating oil film applied is preferably less than 0.9 g/m 2 and is more particularly between 0.2 and 0.5 g/m 2 , since such weights are sufficient to obtain excellent temporary corrosion protection and to avoid any risk of contamination of workshops and forming tools.
  • the subject of the invention is the use of an aqueous treatment solution comprising sulfate ions with a concentration of not less than 0.01 mol/l, in order to improve temporary corrosion protection of a steel sheet coated with a metal layer based on zinc or its alloys.
  • This aqueous treatment solution is applied to the steel sheet according to the embodiments described in the paragraphs relating to the use of an aqueous treatment solution containing sulfate ions for treating a galvanized steel sheet for the purpose of reducing degradation of the zinc coating while the sheet is being formed.
  • the reader may refer to the paragraphs relating thereto.
  • the inventors have shown that the temporary corrosion protection of a galvanized steel sheet firstly treated with a treatment solution according to the invention and then coated with an oil film is very much better than that of a galvanized steel sheet that has not been treated beforehand.
  • FIG. 1 illustrates the results of the friction tests carried out on various sheet test pieces treated according to the invention or untreated;
  • FIG. 2 illustrates the results of the hot/wet corrosion tests carried out on various sheet test pieces according to the invention or untreated.
  • Test pieces were cut from a steel sheet, of “aluminum-killed steel” grade and of ES quality, with a thickness of 0.7 mm and coated on each of its sides with a zinc coating produced by hot dipping in a zinc bath.
  • An aqueous treatment solution according to the invention obtained from 125 g/l of zinc sulfate heptahydrate ZnSO 4 ⁇ 7H 2 O was prepared.
  • this treatment solution was applied to some of the test pieces by spraying the treatment solution at a temperature of 40° C. After the sheet was in contact with the solution for a time of 3 to 4 s, the treated sheet was drained and then dried.
  • a lubricating oil film was then applied to the zinc hydroxysulfate/zinc sulfate-based layer formed on the surface of the galvanized steel sheet test pieces, said oil being either QUAKER 6130 oil (from Quaker) or FUCHS 4107S oil (from Fuchs), with a film weight of 1.5 g/m 2 .
  • test pieces that had not been pretreated with the treatment solution according to the invention were oiled, either with the QUAKER 6130 oil or with the FUCHS 4107S oil, again with a film weight of 1.5 g/m 2 .
  • test pieces were then subjected to a controlled deformation test by means of a press comprising a punch, a die and a blank holder, recreating in the laboratory the stresses undergone by the sheet during a drawing operation, especially in the die radii and/or in the retaining rings with which the drawing tools are equipped.
  • Various blank-holder clamping forces were applied to the test pieces undergoing the test.
  • test pieces of the two series were weighed before the oiling operation and then at the end of the test, after de-oiling, by means of a balance accurate to 0.0001 grams.
  • the measured difference in weight was normalized to a weight loss per square meter, taking into account the area affected by the friction during the simulation of drawing the test piece, which was identical for each of the test pieces.
  • the press was wiped so as to identify the zinc coating powder or particles lost by the test piece in the press.
  • the weight loss results of the test pieces after drawing and the identification of zinc powder and/or particles coming from the coating are given in Table 1.
  • the particles and/or powder are identified by a rating in the following manner, according to a scale ranging from 1 to 4, where:
  • Test pieces 1 cm 2 in area were cut from a steel sheet, of “aluminum-killed steel” grade and of ES quality, with a thickness of 0.7 mm and coated on each of its sides with a zinc coating produced by hot dipping in a zinc bath.
  • test pieces were treated with a treatment solution according to the invention, under the same conditions as those indicated in Example 1, so as to form a zinc hydroxysulfate/zinc sulfate-based layer.
  • a lubricating oil film (QUAKER 6130 oil) is then applied to this layer in amounts ranging between 0.25 and 2.5 g/m 2 .
  • test pieces were oiled in the same manner as previously, but without having been pretreated with the treatment solution according to the invention.
  • the tester was a flat-on-flat tribometer known per se.
  • the test pieces to be tested were clamped with a clamping force F c between two high-speed steel plates offering a bearing (or sliding) surface to the test pieces.
  • the friction coefficient N was measured while moving the test piece relative to the plates over a total travel D of 180 mm and at a speed of 10 nm/s, while progressively increasing the clamping force F c .
  • a curve showing the variation in friction coefficient as a function of the clamping force F c for different lubricating oil film weights can then be plotted (see FIG. 1 ).
  • Test pieces were cut from a steel sheet, of “aluminum-killed steel” grade and of ES quality, with a thickness of 0.7 mm and coated on each of its sides with a zinc coating produced by hot dipping in a zinc bath.
  • test pieces were treated with a treatment solution according to the invention, under the same conditions as those indicated in Example 1, so as to form a zinc hydroxysulfate/zinc sulfate-based layer.
  • a lubricating oil film (QUAKER 6130 oil) was then applied to this layer in weights ranging between 0.25 and 1.0 g/m 2 .
  • test pieces were oiled in the same manner as previously, but without having been pretreated with the treatment solution according to the invention.
  • the lubricating oils applied to the steel sheets coated with the zinc-based metal coating guaranteed corrosion protection during the period of time that elapsed between manufacture of the sheets and their processing, for example by drawing.
  • test pieces to be tested were placed in an environmental chamber corresponding to the DIN 50017 standard, which simulates the conditions for corrosion of the external turn of a coil of sheet or of an individual cut sheet during storage.
  • test pieces were suspended vertically.
  • a curve showing the variation in the percentage content of white rust as a function of the number of cycles for each of the test pieces tested can then be plotted (cf. FIG. 2 ).
