Definitions

  • the present invention relates to a method for improving the corrosion resistance of metallic materials such as stainless steels, ordinary steels, low-alloy steels, carbon steels, processing steels, refractory steels, nickel-based alloys and based on cobalt, aluminum and its alloys, titanium and its alloys, zirconium and its alloys, zinc and its alloys, copper and its alloys.
  • metallic materials such as stainless steels, ordinary steels, low-alloy steels, carbon steels, processing steels, refractory steels, nickel-based alloys and based on cobalt, aluminum and its alloys, titanium and its alloys, zirconium and its alloys, zinc and its alloys, copper and its alloys.
  • the present invention therefore relates to a method for improving the corrosion resistance of a metallic material, characterized in that the metallic metallic material is subjected to cold surface treatment by plasma at low temperature, at a pressure of 1 to 103 Pa, in an atmosphere comprising at least one gas chosen from oxygen, ozone, nitrogen, hydrogen, air, carbon dioxide , carbon monoxide, nitrogen oxides, water, flue gases and mixtures thereof with neutral gas.
  • low temperature plasma or "cold” plasma is generally meant a plasma obtained by glow discharge in a low pressure atmosphere (less than 103 Pa).
  • the discharge is obtained in an enclosure between an anode and the negatively polarized metallic material which serves as a cathode.
  • the metallic material to be treated is kept “cold”, that is to say that its temperature is maintained in practice at a temperature below 100 ° C. This can be achieved through the use of a cathode and an anode cooled by a circulation of water.
  • the molecules of the gas are dissociated, excited or ionized; in the electrical discharge thus created, a low energy plasma scans the surface of the material and the various gaseous species react with the surface atoms according to their chemical affinity. A large number of elements disappear from the treated surface depending on whether the gases are oxidizing or reducing. After treatment, the surface is generally passive vis-à-vis the atmosphere, that is to say, conventional pollution elements C, S, P O, ...
  • reaction products for the most part, certainly in gaseous form, are evacuated by pumping and others, positively charged can redeposit on the cathode, for example calcium, but without, however, disturbing the surface.
  • neutral gas means rare gases such as argon, neon and helium.
  • Particularly suitable gas atmospheres are N2 / O2 mixtures, including air, carbon dioxide, N2 / H2, H2 / Ar.
  • Processing times can be from about 1 second to 10 minutes. It is advantageous to operate at voltages from 100 to 5000 V.
  • results indicated above can be obtained by electric or electromagnetic fields generated by the conventional techniques of "cold" plasma usually used for physical vapor deposition (magnetron, ion or electron guns, conventional ionic deposits) or thermochemical treatments by ion bombardment.
  • the gas used was a 80/20 N2 / O2 mixture.
  • an argon atmosphere was used.
  • the material was examined before and after treatment.
  • the corrosion resistance was also evaluated by the drop test.
  • This test consists in depositing for 5 minutes a drop of the following solution 17 ml FeCl3 at 28% 2.5 ml HCl 5 g NaCl 188.5 ml distilled water
  • the attack on the metal is rated from 1 to 3 in increasing order of attack on the metal.
  • Tests were carried out similar to those carried out in Example 1 on a ferritic stainless steel containing 17% Cr and 1% Mo (reference FMo). The conditions are the same, except with CO2 where the voltage has been chosen equal to 400 V so that the discharge can be established.
  • a treatment test was carried out as in Example 1 on bare sheets of mild steel and treated under a voltage of 400 volts with a current of 200 mA in different gases at a pressure of 103 Pa. - 5 min under cold plasma N2 / H2 (90/10) - 5 min under cold plasma N2 / O2 (80/20)
  • the sheets having undergone a N2-O2 treatment exhibit numerous pitting.
  • Figure 1 shows different characteristic curves determining the surface concentrations of elements such as C, P, S, N2, Si and Mn.
