Definitions

  • the invention relates to a method for producing a part with very high mechanical characteristics, shaped by hot stamping, from a strip of rolled steel sheet and in particular hot rolled and coated with a metal or a metal alloy providing protection of the surface and steel.
  • the steel sheets to be subjected to high temperature forming and / or a heat treatment are not delivered coated for reasons of resistance of the coating during the heat treatment, the heat treatment of the steels generally being carried out at relatively high temperatures well above 700 ° C. Indeed, a coating of zinc deposited on a metal surface has been considered until now as being able to melt, flow, foul the hot forming tools, during heating, at temperatures above the melting temperature of zinc , and degrade during rapid cooling. The coating is therefore performed on finished part which requires a careful cleaning of surfaces and hollow parts. This cleaning requires the use of acids and / or bases whose recycling and storage are a significant financial burden and present risks for operators and the environment.
  • the heat treatment must be carried out under a controlled atmosphere in order to avoid decarburization and oxidation of the steel. Then, in the case of hot forming, calamine, by its abrasive power, damages the forming tools, which reduces the quality of the parts obtained from the dimensional and aesthetic point of view or requires frequent and expensive repairs tools. Finally, to increase their resistance to corrosion, the parts thus obtained must receive an expensive post-processing whose application is difficult or impossible, especially in the case of parts with depressions.
  • the post-coatings of steels with very high mechanical characteristics also have the disadvantage of creating hydrogen embrittlement risks in electro-galvanizing techniques or modifying the mechanical properties of these steels in dip galvanizing techniques. previously formed parts.
  • the object of the invention is to propose to the users, steel sheets rolled from 0.2 mm to about 4 mm thick, coated in particular after hot rolling, and to be subjected to hot forming as well as a method of producing a part by hot forming, from these coated steel sheets, the temperature rise being ensured without decarburization of the steel of the sheet, without oxidation of the surface of said sheet, before, during and after hot shaping.
  • the method according to the invention as shown in the diagram of Figure 1 consists of a sheet of a steel for heat treatment and hot forming including hot rolled and coated with zinc or a base alloy zinc, in the production of hot formed part by means of tool such as a stamping press.
  • the zinc or zinc alloy coating is selected so as to provide corrosion protection for the base sheet in a coil.
  • the coating forms a layer which combines with the steel of the strip and present at this moment a mechanical strength avoiding the melting of coating metal.
  • the formed compound has high resistance to corrosion, abrasion, wear and fatigue.
  • the coating does not alter the formability properties of the steel and thus allows a wide variety of cold and hot forming.
  • the strip After hot rolling, the strip can be pickled and cold rolled before being coated. In the case where the sheet is cold rolled, it can be annealed before being coated.
  • the rolled sheet can be coated, for example, with zinc, or zinc aluminum alloys.
  • the sheet may be cold drawn to obtain the part.
  • the resulting part is then subjected to a heat treatment to give it high mechanical characteristics.
  • a base steel having a breaking strength Rm of about 500 MPa will make it possible to obtain heat-treated parts having a steel with a resistance Rm greater than 1500 MPa.
  • the sheet is subjected to a temperature rise preferably between 700 ° C and 1200 ° C in a furnace with an atmosphere no longer requiring control, because of the barrier to oxidation formed by the coating.
  • a temperature rise preferably between 700 ° C and 1200 ° C in a furnace with an atmosphere no longer requiring control, because of the barrier to oxidation formed by the coating.
  • the zinc-based coating is transformed into an alloyed surface layer having different phases depending on the temperature treatment and having a high hardness of more than 600 HV 100g.
  • sheets having a thickness of between 0.2 mm and 4 mm may be used, having good shaping properties as well as good corrosion resistance.
  • the sheets delivered coated have a significant resistance to corrosion during temperature rises, shaping, heat treatments, and during the use of finished formed parts.
  • the presence of the coating during hot forming avoids in addition to corrosion, the decarburization of the base steel.
  • This has an undeniable advantage in the case of hot forming, for example in a stamping press.
  • the formed intermetallic alloy avoids the formation of calamine, the wear of the tools by calamine, and thereby allows an extension of the average life of said tools. It has been noticed that the hot formed intermetallic alloy has a high temperature lubricant function.
  • the effect of protection against decarburization of the intermetallic alloy allows the use of high temperature furnace exceeding 900 ° C having an uncontrolled atmosphere, and this, even for heating times of several minutes.
  • the parts obtained Due to the characteristics of the coating after temperature rise, the parts obtained have an increased resistance to fatigue, wear, abrasion and corrosion, including on the wafer because of the galvanic behavior of the zinc with the steel.
  • the coating is weldable before and after temperature rise.
  • the steel of the sheet ensures, by cooling quenching effect, high mechanical characteristics of the part obtained after forming, the coating converted into a hot intermetallic alloy, for its part, because of its lubricant qualities and resistance to friction, an improvement in shaping, especially in the field of hot stamping.
  • Example 1 zinc coating on steel.
  • One piece is made from cold-rolled steel sheet 1mm thick and galvanized continuously double-sided, with a coating thickness of about 10 microns.
  • the sheet is austenitized at 950 ° C. before hot forming and quenched in the tool, the coating acting as a lubricant during shaping, in addition to its functions of protection against cold, hot and cold corrosion. decarburization.
  • the alloy coating does not interfere with the extraction of heat by the tool and can promote it. After forming and quenching, it is no longer necessary to strip the part or to protect it, the base coating providing protection throughout the process.
  • the part produced is of a matte gray appearance without sag or bubble, without flaking or cracks, and not presenting no calamine on the slice, in section.
  • Scanning electron microscopic observations show on the surface and in section that the coating retains a homogeneous structure and texture and that Fe-Zn alliation occurs in less than 5 minutes at 950 ° C.
  • the coating comprises as shown in a comparative manner in FIGS. 3a and 3b respectively representing, in section, the coating before and after heat treatment, a Zn diffusion interface, with a thickness of between 5 and 10 ⁇ m, is a layer formed by nodules of Zn-Fe alloy in a zinc matrix, layer with a thickness of between 10 and 15 ⁇ m.
  • Table 1 below shows the loss of corrosion mass after 500 and 1000 hours of salt spray, for an uncoated reference steel, for a galvanized reference steel without heat treatment, and a steel according to two forms of the invention.
  • Table 1 Loss of mass in g / m 2 After 500 hours Loss of mass in g / m 2 After 1000 hours
  • the coating after heat treatment is resistant to salt spray.
  • this surface composed of zinc and iron, can be phosphated in conventional surface treatment baths of the phosphating type.
  • the corrosion tests carried out after phosphating and cataphoresis painting show excellent results.
  • the zinc iron alloy layer also provides galvanic protection for cathodic protection type slices.
  • Example 2 zinc aluminum coating on steel.
  • a 10 ⁇ m coating is applied to a sheet of about 1 mm.
  • This coating is composed of 50 to 55% aluminum and 45 to 50% zinc with possibly a small amount of silicon.
