The term galvanic (or electroplating) refers to a set of techniques for coating certain products and artefacts for both functional and aesthetic purposes, to protect them from the effects of corrosion and wear and, at the same time, to make them more pleasant in appearance.
When we talk about the large sector that makes up metal plating, we are rightly talking about galvanic treatments, galvanic processes and galvanic baths. But what do these expressions mean, and what do they refer to?
Let’s see it in detail.
Galvanic meaning and origins
Galvanics is a sector that has conceptual origins as early as the 18th century and which experienced significant growth in the following decades, especially thanks to the development of modern technologies.
Currently, galvanic is considered already mature from an industrial point of view, since it has been applied for over a hundred years now. In fact, its evolution has been truly impressive and today, thanks to galvanic treatments, it is possible to improve certain characteristics of products and manufactured articles, such as resistance to corrosion or its electrical, mechanical and optical properties.
What does galvanic do?
Galvanic technology is used on an industrial level through specific plants and procedures, and is more precisely realized through galvanic treatments, also called surface treatments.
But what exactly are galvanic industrial treatments? And how are the galvanic coatings made?
The galvanic treatment consists in the coating of metals through the use of thin layers of alloys or other specific metals, which are deposited electrolytic, i.e. through a complex electrochemical process. After a complex process of preparing the surface of the metal to be treated, therefore, the coating is deposited. The alteration of the metal surface, inevitable following the treatment, involves the enhancement of the qualities of the same.
In fact, intervening on metals using galvanic treatments is often essential, since any metal inevitably undergoes wear and deterioration over time. The purpose of electroplating is therefore twofold: to make the metal subjected to the treatment on the one hand more resistant, durable, performing and on the other hand more aesthetically pleasing.
The galvanic treatments of Eurogalvano Srl
Eurogalvano Srl has been operating in the field of galvanic and metal surface treatments for years.
Always at the forefront and attentive to new technological developments, our company looks to professionalism, experience and constant commitment as fundamental tools to satisfy its customers and a constantly evolving market.
Over the years we have enriched our treatment park with new systems, acquired innovative tools and machinery as well as certifications that demonstrate even more clearly our commitment and our ability to serve the needs of customers. We have a laboratory equipped with ultra-modern equipment that allows us both to carry out specific checks requested by our customers and to issue certificates relating to the outcome of the checks on surface treatments. Always keeping an eye on the environment as well, and aimed at finding innovative solutions aimed at saving energy, the company is characterized by the presence of a particularly modern galvanic department, which is made up of both automatic and semi-automatic lines.
We at Eurogalvano Srl offer our services to many sectors and in particular to the mechanical one. Particularly numerous interventions are carried out in specific sectors such as the automotive, railway, gunsmiths, thermo-sanitary and textile sectors. The treatments that are particularly required are varied and take place on both ferrous and non-ferrous metals.
Below are our galvanic processing treatments.
Hard Chrome
The hard chromium plating process has the purpose of creating shiny and opaque and wear-resistant hard chrome deposits, with thicknesses up to 100 µm and directly on the object to be coated, therefore without the interposition of copper or nickel layers.
Decorative Chrome
The electrolytic decorative chrome process has the purpose of creating deposits of shiny, matt, “classic” pearl and “3Q7 type” pearl on smooth or previously satin-finished surfaces.
Aluminum Treatment
Chromium plating on aluminum is essential because this material too, used for the production of numerous items all over the world, is not immune to the effects of wear.
Alkaline Copper
The electrolytic alkaline copper plating process has the purpose of preparing the surfaces of the various details to receive any further treatments.
Acid Copper
The acid electrolytic thick copper plating process has the purpose of creating very thick deposits of copper to level and improve the surfaces of the various details, with a notable aesthetic qualitative increase.
Nichel Pearl
The electrolytic nickel process is carried out to create deposits of “classic” pearl nickel and “3Q7 type” pearl nickel (shinier, no fingerprints remain) on smooth surfaces.
Nichel Satin Polished
The electrolytic nickel process has the purpose of making bright or dull nickel deposits on smooth or previously satin-finished surfaces.
Phosphating
Manganese phosphating (or phosphating) is a dark gray coating of phosphate material with anti-rust and anti-seize properties.
Bright Decorative Brass Plating
The electrolytic decorative and thick brass plating process aims to create deposits of shiny, opaque, pearl brass on smooth or previously satin-finished surfaces.
Preparation for treatment
Among surface preparations, grinding allows the metal to reach an appropriate level of smoothness; tumbling takes place dry or wet; Sandblasting is a mechanical cleaning of surfaces.
