Definitions

  • a common practice to improve the press-formability of zinc-based plated steel sheet is a method of coating a high viscosity lubricant oil.
  • the method has problems such as the generation of defects during the painting stage caused by insufficient degreasing, and the instable press-formability during the press-forming stage caused by absence of the lubricant oil.
  • minimization of the quantity of lubricant oil is an effective means. To do this, however, the improvement in the press-formability of zinc-based plated steel sheet is required.
  • the average Fe concentration in the alloy layer increases, the ⁇ phase which is hard and brittle is likely formed at the interface between the plating and the steel sheet, thereby likely inducing a phenomenon of peeling of plating (what is called the "powdering") in the vicinity of the interface during the press-forming stage.
  • JP-A-4-88196 discloses a technology to improve the press-formability and the phosphatability by forming an oxide film composed mainly of a P oxide on the surface of a zinc-based plated steel sheet by dipping the steel sheet in an aqueous solution of pH 2 to 6, containing 5 to 6 g/liter of sodium phosphate, by applying electrodeposition treatment in the aqueous solution, or by spraying the aqueous solution onto the steel sheet.
  • the film of an oxide containing Zn and Fe likely becomes fine lamellar-like oxides compared with the film of oxide only of Zn, which likely forms coarse plate-like oxides.
  • the present invention is also applicable to a galvannealed steel sheet on which the hot dip galvanizing layer is processed by alloying treatment.
  • the Fe ion reduction reaction begins to precipitate trace amount of Fe on the surface of plating layer , which suppresses the excess growth of the film of O-containing compound composed mainly of Zn, thereby forming a film of very fine compound.
  • the film composed of a compound containing Zn, Fe, and O contains elements such as F, Mg, Al, Si, P, S, Cl, K, Ca, and Ba, existing in the acidic solution, or contains adsorbed water, the effect of the present invention is not deteriorated.
  • the film is not necessarily formed continuously, and the film covering not the whole area of plateau is also effective. Nevertheless, to decrease the friction resistance, the film preferably covers 60% or more of the plateau.
  • Galvannealed layer was formed on each of cold-rolled steel sheets having 0.8 mm of thickness using an ordinary method, which plated steel sheets were then processed by temper-rolling. After that, a film was formed on the surface of zinc plating layer under the respective treatment conditions given in Table 1 to prepare the sample Nos. 1 to 22.
  • a comparative sample 11 for determining the coefficient of friction is fixed on a sample table 12 which is fixed on the upper face of a horizontally movable slide table 13.
  • a vertically movable slide table support 15 equipped with a roller 14 contacting with the slide table 13.
  • a first load cell 17 is attached to the slide table support 15.
  • the first load cell determines the pressing load N applied from a bead 16 to the sample 11 by pushing-up the slide table support 15.
  • a second load cell 18 is attached to an end of the slide table 13.
  • the second load cell 18 determines the sliding resistance F by moving the slide table 13 in the horizontal direction in a state of pressing the bead 16 against the comparative sample 11.
  • the tests were conducted by coating a lubricant oil on the surface of the comparative sample 11.
  • the applied lubricant oil was PRETON R352L, a washing oil for press-work manufactured by Sugimura Chemical Industrial Co., Ltd.
  • Figure 2 and Fig. 3 show the shapes of applied beads.
  • the bead 16 shown in Fig. 2 has the dimensions of 10 mm in width, 12 mm in the length in the sliding direction, 3 mm in the length in the sliding direction to which the sample is pressed, and 4.5 mm in the radius at each end in the sliding direction.
  • Figure 6 is a schematic drawing of the draw-bead tester used in the examples.
  • the steel sheet was dipped into an acidic solution at 50°C and pH 2.0 to form a liquid film on the surface of the steel sheet using squeeze rolls 3.
  • the formed liquid film was washed in a washing tank 5 by spraying hot water at 50 °C against the steel sheet, and then the steel sheet was passed through a neutralization tank 6 without applying neutralization.
  • the steel sheet was washed by spraying water at 50°C thereto in a washing tank 7, followed by drying in a drier 8, thus forming the film on the surface of plating layer.
  • the quantity of liquid film was adjusted by varying the pressure of squeeze rolls 3.
  • the acidic solution in the acidic solution tank 2 was an acidic solution which contained a pH buffer prepared by mixing 30 g/liter of disodium hydrogenphosphate and 20 g/liter of citric acid, adding a specific amount of iron (II) sulfate to add Fe ion thereto, and further adding sulfuric acid to adjust pH.
  • a pH buffer prepared by mixing 30 g/liter of disodium hydrogenphosphate and 20 g/liter of citric acid, adding a specific amount of iron (II) sulfate to add Fe ion thereto, and further adding sulfuric acid to adjust pH.
  • an acidic solution containing only iron (II) sulfate, not containing pH buffer was used, (Sample Nos. 3 to 5).
  • an acidic solution containing Fe(III) sulfate was also applied to some of the samples, (sample Nos. 18 to 23).
