Eloksal Anodization

The colourless layers of anodic oxide formed in a process held in sulphuric acid baths, employing direct current under low temperatures are called "natural anodized layers".  It is possible to colourise these layers in chemical terms, using inorganic or organic compounds based paints.

Practices are generally for technical purposes. Very thick and hard anodic oxidation layers may be obtained depending on the material used and the intended area of use. Additionally, opaque and bright anodic oxidation coats can also be produced. 

As the anodic oxidation layer presents an extremely hard and thus highly anti-corrosive surface, it adds superior qualities to aluminium. Anodic oxidation coating provides high anti-corrosive properties to aluminium under a vast majority of conditions, as it is resilient against a variety of acids and other chemicals. The transparent structure of the anodised layer reveals the metallic appearance of aluminium, which fact makes it possible to apply a variety of mechanical or chemical processes on the surface of aluminium, to give it a bright or matte appearance .

   Hard Anodizing

Hard anodizing procedures are carried out for industrial applications. It is preferred particularly in a variety of engineering applications, where extremely hard surfacing layers with good anti-friction properties are sought on aluminium materials. Hard anodized oxide layers can have a thickness in a range of 25 to 150 microns.


   Alodine Chromating

The term defines a process of creating a film layer by chemical means, in order to facilitate for the strengthening the bond between the paint and the application surface, by amplifying the anti-corrosive resistance of aluminium and alloys. The production is carried out to yield colourless, brown or yellowish products.




   Aluminium Surface Treatment

This is a process designed and developed especially for aluminium materials, to optimise the bonding of the next painting layers, which is free of CR+6. As an outcome of a huge knowledge accumulation, this product names a technology that passivises CR+3.

The aluminium surface treatment gives a shot appearance in light blue and transparent green colours with a thin CR+3 passivation film layer applied on material.

The process meets the requirements of RoHS and WEEE.
It is proposed for providing resistance in such accelerated corrosion tests as the salt spray test.
The aluminium surfaces are cleaned by pre-treatment, in other words, porosities are made to occur on them to prepare them for the upcoming surface treatment.

Cataphoresis Coating
> General Description

Known as the product of "electro-plating", Cataphoresis defines a hi-tech, low emission, environmentally friendly category of water based coating systems, which provide high corrosive resistance thanks to a film layer that corresponds to the metallic application surface, being originally developed to provide a solution to the increasing demand for quality especially in car making and durable whites manufacturing industries.  

Electro-plating takes place through four different electro-chemical reactions. Electrolysis is the separation of water at anodic and cathodic bars so called "electrodes" with the application of voltage. Electrophoresis is the motion of dispersed particles carrying negative charges relative to a fluid under the influence of a spatially uniform electric field. Electro deposition is the process of coating athin layer of one metal on top of a differentmetal to modify its surface properties, towards achieving bondage of the coat layer on metallic surface to enable the paint set.  Electro endosmosis is the process of compressing paint particles.

Nickel Coating
   Nickel Coating

Nickel coating procedures are most widely used for decorative and engineering purposes.

Nickel is perhaps the most frequently used material in electro-plating practices. The reason of this is associated with its excellent appearance, high corrosion resistance and the plenitude of hot melts obtainable through the coating process. Nickel is also used for decorative coating purposes due to its ability to add much features to the presentability of the coated material with its polished surface finishes and its high anti-corrosive properties.

   Electroless Nickel Plating

This method is the top choice of preference in industrial applications due to Nickel's high hardness levels, superior wear resistance and features for welding and soldering, as well as to suitability for post thermal processes which further enhance the hardness and wear resistance of the material, in addition to the original high resistance shown by electroless nickel platings in both acidic and wearing media.   Among these features included are perfect wear and corrosion resistance, uniform coat thickness, ability to increase the hardness level by subjecting the material to annealing process when required and the ability to preserve expansion features with changes in temperature.

Tin Coating
   Tin Coating

Tin coating is not the most desirable technique for use alone, due to its poor resistance qualities and relatively higher costs,

It is administered by hot dip submerging and electrolysis techniques on steels.

Thereby the mechanical resistance is obtained with steel, while corrosion resistance is guaranteed with tin. Furthermore

in addition to its being suitable for welding and soldering applications and its sliding features, its completely non-toxic content expands the marketability options of this material, expanding its area of use as a packaging material for the food and foodstuffs industry.  Tin is a soft metal with white appearance. As tin is self-resistant to wear and brings a nice appearance while preserving this property of its under atmospheric conditions, it is most frequently used to form a protective top coat cover on metals which have tendencies towards discolouration and wear, beyond decorative concerns.  Probably the best application of this coat currently is the covering of tin cans, which are meant to store food and drinks. Tin is highly resistant against food acids. Tin coats on such kinds of products will give a less porous and more homogeneous cover by facilitating lesser use of tin material. The cooling coils of refrigerators, dairy tools and instruments as well as all other parts that may get into contact with food are therefore covered with tin coats. Tin is also used to cover such ornamental items as hairpins, garment pins and etc.

Silver Coating
   Silver Coating

Does not oxidise upon contact with air, gives perfect electrical conductivity and lubricant properties, for which reason silver coating should be the choice of preference where work under overload is necessary with liquids and fluids of low lubricant characteristics or decorative concerns are high.  Basically developed for use in plating of cups, cutleries and dining sets, the silver coating technique has proven its suitability for a bunch of other decorative and functional applications, as well as for engineering and electrics - electronics applications. Silver has perfect electrical conductivity.

Copper Coating
   Copper Coating

Despite its fairly high anti-corrosive properties, copper blackens easily when exposed to open air outdoors, which in turn results in unwanted noisy stains on the overall texture, and therefore used only as an undercoat layer for multi-layered coating applications, in general.  Industrial processes may from time to time include or require the use of copper with a view to improve the durability of nickel and chrome coated car parts which are directly exposed to external factors.  Copper coatings have found their primary area of use in almost any applications, due to their ability to fill in and smooth surface irregularities, form a bright cover, protect the underlying metal content against corrosion and to show great inter workability and compliance with nickel and chrome coatings.  Both acidic and alkaline copper coating processes are available.
