Definitions
- the present invention aims to develop an anticorrosion coating of metal parts, free of chromium and derivatives based on chromium and in particular hexavalent chromium, which can preferably be applied in thin layers while being endowed with high protective performances. .
- the invention applies to parts of a metallic nature (in particular steel, cast iron) which require good resistance to corrosion in a thin layer.
- the geometry of the parts has little importance as long as the applicability of the parts by the methods described remains possible.
- the invention makes it possible to improve the anti-corrosion properties of the treated parts without using chromium and in particular hexavalent chromium in the formulation of coatings.
- Many chromium-based anticorrosion treatment solutions have been proposed to date. If they generally give satisfaction in terms of the protection of metallic parts, they are however more and more criticized because of their consequences on the toxic level and in particular because of the harmful consequences on the environment.
- the present invention relates to an anticorrosion coating of metal parts, characterized in that it consists of the synergistic association of a first layer based on metallic zinc and of one or more coating layer (s) obtained. using an aqueous composition containing a particulate metal, a suitable solvent, a thickener and a binder consisting of a silane.
- the first layer based on metallic zinc can for example be advantageously produced by mechanical deposition.
- a layer consisting of zinc or more generally of an alloy of zinc and iron, or even of a mixture of particles of zinc and iron can be applied in the context of the present invention in an amount of between 50 and 300 mg / dm of filler metal. For certain particular applications, we can even be satisfied with lower deposited quantities.
- the mechanical deposition of the layer based on metallic zinc is advantageously obtained by a shot peening operation using steel balls having at least one outer layer comprising either pure zinc or a zinc-based alloy.
- Such a mechanical deposition of a layer based on metallic zinc can also be ensured by a shot peening operation using a mixture of steel balls and balls constituted by a steel core and having on the surface at minus an outer layer based on a zinc alloy or an outer layer of pure zinc.
- this mechanical deposition of the layer based on metallic zinc can also be obtained by shot peening using beads made essentially based on an iron alloy, peening being carried out in the presence of a zinc powder or zinc semolina which is therefore applied under the mechanical effect of shot blasting.
- the term ball or microbead used in the context of the present invention to describe shot peening operations must be understood in the broad sense, that is to say encompass all types of particle or microparticle forms to be projected onto the surfaces rooms.
- the shot blasting machine used to produce this first zinc-based layer can, for example, be produced in accordance with the schematic diagram illustrated in FIG. 1 attached.
- the machine mainly comprises a blasting chamber 10 which can, for example, comprise two projection turbines 12 between which the parts to be treated will pass.
- the projection turbines 12 will therefore project the microbeads of iron alloy or of zinc-based alloy onto the surfaces of the parts to be treated, in the presence, if necessary, of a zinc powder or semolina.
- the lower part of this peening chamber 10 is equipped with a device 14 for recycling the peening balls. These balls are then brought to a particle size separator 16 so as to separate balls of diameter which has become too small.
- a particle size separator 16 so as to separate balls of diameter which has become too small.
- the reservoir 26 of the microbeads which is intended to supply the projection turbines 12 of the blasting device 10, will or may not be replenished with new balls at 28, that is to say charged or recharged with zinc.
- the reservoir 26 is also advantageously equipped with a level control system 30.
- Electrogalvanizing is the metallic deposit of zinc or a zinc-based alloy from an aqueous solution by imposing a direct electric current between the part to be coated and an anode.
- This anode can either be inert, or consist of zinc itself in the form of a ball or plates with a purity of 99.99%.
- the electrolysis bath can be either acidic or alkaline with or without cyanide.
- the electrolysis bath can also contain salts of other metals, thus making it possible to make alloys with zinc (nickel, manganese, iron, cobalt).
- Hot galvanizing is a coating operation by dipping in a bath of molten zinc at a temperature of the order of 460 ° C.
- the second step is the actual galvanization.
- the zinc content of the bath is 99.5%.
- the classic temperature range is between 445 and 460 ° C. The rate of emersion of the parts of the bath will regulate the thickness of the zinc layer.
- such a composition comprises for example:
- said composition contains from 10 to 35% by weight of zinc and / or from 1.5 to 35% by weight of aluminum.
- said composition contains from 3 to 20% by weight of silane.
- the silane derivative used as binder for example advantageously gamma-glycidoxypropyltrimethoxysilane is present in the composition in an amount of between approximately 5 and approximately 12% by weight relative to the total weight of composition.
- said composition contains from 1 to 30% by weight of an organic solvent, in particular dipropylene glycol.
- the organic solvent used in said aqueous composition is a liquid solvent with high boiling point, for example an oxohydroxylated liquid, advantageously chosen from the group consisting of tri- and tetraetylene glycol, di- and tri-propylene glycol, monomethyl. , dimethyl and ethyl ethers of the above glycols, polypropylene glycols, diacetonic alcohol, diethylene glycol ethers and mixtures thereof.
- Said composition also preferably contains from 0.005 to 2% by weight of a thickening agent, in particular hydroxypropylmethylcellulose.
- the particulate metal is used in the form of a powder having a diameter between 1 and 10 ⁇ m, preferably 2-5 ⁇ m, or of particles of small dimensions less than 15 microns, or a mixture of the two.
- the particulate metal may consist of one or two of the metals chosen from zinc and aluminum, their alloys and their intermetallic mixtures in all proportions.
- Said aqueous composition also contains a thickening agent preferably present in an amount of 0.05 to about 2% by weight relative to the total weight of the composition.
- Said thickener will preferably be chosen from the group comprising cellulosic thickeners, xantane gum, modified clays and their mixtures.
- the latter will contain from approximately 0.2 to approximately 1.2% by weight of the thickening agent, preferably chosen from the group comprising hydroxyethylcellulose, methylcellulose, methylhydroxypropylcellulose , ethyhydroxyethycellulose, methylethylcellulose, and mixtures thereof.
- the thickening agent preferably chosen from the group comprising hydroxyethylcellulose, methylcellulose, methylhydroxypropylcellulose , ethyhydroxyethycellulose, methylethylcellulose, and mixtures thereof.
- Said aqueous composition also advantageously contains a wetting agent preferably present in an amount of 0.01 to about 3% by weight relative to the total weight of the composition, said wetting agent preferably being an agent of non-ionic type.
- the aqueous composition may also, under certain conditions, contain from about 0.1 to about 10% by weight of a boron-based compound, for example chosen from orthoboric acid, metaboric acid, tetraboric acid, boron oxide and mixtures thereof.

- said composition contains from approximately 30 to approximately 60% by weight of water relative to the total weight of the composition.
- This composition can be applied to the first layer based on metallic zinc by spraying operations, by soaking or by centrifugal soaking, then subjected to a cooking operation, preferably at a temperature of 70 to 300 ° C.
- the production of said coating layer (s) is carried out so as to obtain on the order of 10 to 20 g / m 2 expressed by weight of dry matter.
- the mechanical deposition of the layer based on metallic zinc by shot blasting was carried out by dry mechanical spraying on steel sheet DC04 using a shot blasting machine called Z-coater DZ-100 sold by the Japanese company SAMPOH, whose operation corresponds to that of the diagram in the appended figure.
- the projection conditions are as follows: - projection rate: 80 kg per minute, - turbine speed: 4,200 revolutions per minute.
