Definitions

  • the present invention has for itsobject a process of protecting the surface of aluminium, magnesium, or their alloys, against attacks by salt solutions,- such as chloride of sodium, or by moist air loaded with particles of these solutions, for instance sea air capable of causing the alteration or corrosion of the metal.
  • salt solutions such as chloride of sodium
  • moist air loaded with particles of these solutions for instance sea air capable of causing the alteration or corrosion of the metal.
  • The. process is essentially characterized by the fact that, by"means of a salt bath, a protecting deposit is formed at the surface of the metal, and that, to form this deposit, use
  • the metal chosen can I give at least two oxidesthe most oxygenated of which gives an alkalisalt soluble in an alkaline solution. By reduction, the corresponding oxide is brought back to the state of sub-oxide.
  • a manganate corresponding to managanic" acid MnO H O will be brought back to the state of'Mn Q or of Mn O which are stable, do not corrode when inuse, and form at the surface of aluminium, for instance, the. desired protecting layer.
  • this layer can be obtained by immersion of the metal part or member in a bath ofthe chosen salt, at a suitable degree of concentration and at a suitable temperature. 'The bath must be rendered alkaline by the'addition of an alkali'car.
  • bonate, droxide For instance for protecting an article made of aluminium, it can be immersed in a boiling solution of carbonate of sodium at about 1%, and of molybdate of sodium or potassium It has been found that the following ess, derived from the preceding one, .procures special advantages concerning the practical industrial carrying'out of the process.
  • the concentration of the solution in alkali carbonate varies but slightly inuse.
  • the treatment of the article to beprotected is efi'ected at boiling point; the duration of the treatment depends on the thickness of the deposit it is desired to obtain.
  • the protecting layer constitutes an excellent holding surface for any varnish, paint,
  • Claims Process for protecting articles made of aluminium, magnesium, or their alloys, against corrosion, of the said articles in a bath containing carbonate of soda and an alkali salt of the most oxygenated oxide of a metal capable of forming at least two oxides the mostoxygenated' one being soluble .in alkaline solution and the less oxygenated one being insoluble.
  • Process for protecting articles made of 1M comprising the treatment aluminium, magnesium, or their alloys, against corrosion, comprising the treatment of the said articles in a bath containing carbonate of soda and a mixture of alkali sul- 5 pho-molybdate and alkali phospho chromatei 3.
  • uranium, niobium, manganese and chromium are uranium, niobium, manganese and chromium.
  • ath containing carbonate of soda and an alkali salt of, a metal capable of givin atleast two oxides, such as vanadium, moly denum, tungsten, titanium, uranium, niobium, manganese and chromium.
