Definitions

  • the invention relates to a method for producing a part with very high mechanical characteristics, shaped by stamping, from a strip of rolled steel sheet and in particular hot rolled and coated with a metal or metal. 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 undergo a shaping, cold followed by 'a treatment thermal, as well as a method of forming part by 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 the heat treatment.
  • the invention also relates to the use of a strip of rolled and in particular hot-rolled steel sheet coated with zinc or a zinc-based alloy providing protection of the surface and steel of the sheet metal.
  • the parts having high mechanical properties in hardness and high surface hardness characteristics and a very good resistance to abrasion.
  • the process presented in the diagram of the figure 1 consists, from a sheet of a steel for heat treatment and hot forming, in particular hot rolled and coated with zinc or a zinc-based alloy, in the production of a hot-formed part in the form of tool means 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 is cold stamped to obtain the piece.
  • 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 heat treatments makes it possible to avoid, in addition to corrosion, the decarburization of the base steel.
  • 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 shaping.
  • Example 1 zinc coating on steel.
  • One piece is made from cold-rolled steel sheet 1 mm thick and galvanized continuously double-sided, with a coating thickness of about 10 microns.
  • the sheet is austenitized at 950 ° C. before forming and quenching in the tool, the coating acting as a lubricant during shaping, in addition to its protective functions against cold corrosion, hot and against 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 matt 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.
