  1. Anodizing: this electrochemical process passes a direct current of about 2000A with a voltage of 10V or 15V through the material to be anodized, depositing a thin layer of oxide that will gradually become part of the material, giving it multiple properties. All colors except white.
    1. Natural: Application standard S/N MIL-A-8625F  TIPO II  CL 1
    2. With coloring: Application standard S/N MIL-A-8625F  TIPO II  CL 2

  2. Hard anodizing: it is achieved at low temperatures (0ºC) in a strong current density and with a voltage that can rise to 80ºC or 100ºC depending on the material to be treated. A vigorous stirring with effective cooling is necessary. As thicknesses achieved are higher than those of conventional anodizing, the hardness is also higher. It is applied to parts subject to friction.

Projection of abrasive materials (previously selected according to the surface to be cleaned as well as the roughness to be achieved) at high speed on the surface of a substrate. The impact of these abrasives cleans the surface of impurities (such as surface oxides, lamination scale, incrustations of foreign materials …) generating a certain roughness favorable for adhesion and anchoring of future paint layers. This gain in roughness can also be used in more decorative finishing work to achieve a certain grip, for example on glass floors.

As the impact of the abrasives produces excellent roughness to anchor the next layers of paint Sand Blastingt is an efficient and effective mechanical procedure for cleaning and preparing metal surfaces prior to the painting process. The level of roughness is mainly determined by the size and shape of the abrasive material. This process is also used for other more decorative purposes where there is no paint application afterwards, taking advantage of its roughness generation function in the piece to be treated.

The abrasive material could reach high temperatures during the impact process and due to factors such as working pressure, nozzle diameter, distance, angle … melting and becoming part of the blasted surface ( this effect is known as triboplasm ). That is why the blasting abrasive material must be carefully selected according to the material to be treated in order to avoid galvanic torques and contaminate the new surface.

1. Chemical Nickel Plating: this procedure deposits a Nickel-Phosphor alloy without any external current source. 

It offers exceptional technical solutions for its unbeatable qualities of hardness, resistance to wear, friction, abrasion, corrosion …Most remarkable features:

Uniform thickness: provides exactly the same protection against corrosion in all areas of the part. It differs from the electrolytic coating in that it deposits very different thicknesses from one point to another of the piece, beginning the corrosion in these areas where the deposits are weaker.

Variable properties according to the heat treatments carried out: the influence of the heat treatments is due to the fact that the deposition of Chemical Nickel is an alloy, so that its molecular structure changes in the presence of temperature. One of the most common heat treatments is the one we apply to increase the hardness of the coating that can reach 1,100 Vickers.

It can be applied on most metals: such as cast iron, carbon and alloy steels, stainless steels, aluminum, copper, cobalt, monel, nickel and alloys, gold, silver, uranium … even certain thermoset plastic materials such as bakelite, melamine , ceramic, glass, as long as we apply a powerful catalyst to its surface.

Painting process is the set of operations necessary for the application of a paint in order to satisfy and comply with the previously established quality, cost, colour, deadline and safety requirements.

Paint is defined as a coating material in a liquid or solid state which adheres and hardens to form a film that protects, decorates or adds some specific function to the surface on which it has been deposited after being spread on a Surface.

Phases of the painting process:

  1. Surface preparation: Elimination of any contaminant that could be found on the surface to be painted and creation of mechanical and / or chemical anchors (roughness, increase in surface energy, etc.) to favor the adhesion of future paint layers. It will depend on the contaminants that you want to remove, the degree of anchorage / adhesion that we want to obtain and especiallly on the composition, geometry and thickness of the material we want to prepare.
  2. Cleaning and degreasing of surfaces: Its purpose is the elimination of different contaminants that may exist on the surface of a material, such as fats, oils, dust or others, due to the transport, handling or storage of materials.
  3. Masked: Its main objective is to protect certain areas or areas of the structure or part that we do not want to paint.
  4. Primer application: Set of coatings applied as the first layer of the paint system to protect the surface from corrosion and facilitate adhesion to the following layers of Paint.
  5. Application of the paint: It begins with the operation of mixing the components that make up the paint, generally most of the current paints are 2-component (resin and hardener) that have to be mixed homogeneously under the parameters indicated by the manufacturer of paint to obtain the desired viscosity. The selected technique for applying the paint (brushes, rollers or gloves, spray guns, electrostatic guns, immersion, electrophoresis, etc.) will depend on parameters such as the number of pieces to be painted, the geometry and size of this pieces, part material, aesthetic requirements, environmental regulations, cost, selected paint products, etc..
  6. Curing of the paint: Waiting time in which the paint goes from a liquid state to a solid state (drying time). It can be decreased by using the right tools and materials.
    Curing = Drying (process of evaporation of all solvents and diluents added to the paint in order to make it liquid or to reduce its viscosity) + Hardening (the main resin of the paint is created and then hardens with all the other pigments and additives that compose it, creating a solid and adherent coating).

7. Final inspection


  1. Protection against oxidation, corrosion and material degradation.


    The insulating layer between the material and the exterior prevents the action of external agents such as humidity, saline environments, ultraviolet radiation, chemical products, etc. which can induce and cause phenomena such as oxidation, corrosion or degradation to the material.

  2. Decoration and beautification of materials and surfaces.

    It is possible to achieve a wide range of colors as well as decorative effects (chameleon effect, mercury effect, etc.) which enhance and make surfaces more attractive due to the pigments and additives incorporated in the paints.

  3. One of the advantages of Anodizing Yachts is that we have a spectrophotometre to read the color that is applied to the part, formulate it and make a paint repair without changing the color of it.

Electrostatic application of organic powder to metal parts that require coating for protection or decoration. The most widely used method is the application by means of electrostatic guns that transfer an electrical charge to the particles that make up the powder paint at the gun outlet. Once charged, the paint is attracted and covers the entire surface of the piece, which is electrically charged with an opposite sign, resulting in attractive forces between the paint and the piece to be painted responsible of covering the entire of the part surface. Once the piece is covered with powder, it melts on the surface by exposing it to high temperatures (over 200ºC). Then it cools, resulting in a coating perfectly adhered to the surface of the piece.

This type of coating the material is 100% solid and is in a dry state in the form of a fine powder. Once the powder is applied, it covers the surface of the piece and melts into it through the application of heat, generating a highly adhered layer to the surface and providing it with properties of resistance both chemical (corrosion, aggressive chemical agents …) and physical (light, hardness …), as well as aesthetic properties (color, shine, desired texture …). They are also called thermosetting paints or electrostatic paints.

They consist of resins (epoxy, polyester, epoxy-polyester, polyurethane, acrylic), hardeners, pigments, fillers and additives (anti-graffiti, antimicrobial, antistatic …). It is a 100% solvent-free paint system.

Phases of the process:

  1. Pre-treatment:
    1. Abrasive, mechanical or chemical cleaning.
    2. Drying.
    3. Cooling.
  2. Application of the powder: the powder is electrically charged as it is applied to the piece, giving each particle a negative charge. The part to be coated is electrically grounded as a means of attracting and bonding the charged powder to the surface of the part in a uniform layer of dry powder.
  3. Curing: the piece is introduced into the curing oven in which the powdered gels flow and cure, generating a smooth product with a long-lasting finish, through a chemical crosslinking reaction between the powder particles.
