Galvanic treating

Electroplating consists in applying a metal coating to the surface with the help of specialized technology. This treatment consists in reducing direct and indirect losses due to corrosion of metals, i.e. processes of destroying their structure under the influence of the environment (eg air, industrial gases, fresh and sea water, soil, including soil). Activities are undertaken at the stage of:
– design of devices and installations – eg selection of construction materials (eg acid-proof steel, heat-resisting steel),
– design of equipment and installations (eg construction of reactors and pipelines, methods of joining elements, selection of a corrosion protection system)
– operation of protected devices and structures – eg drying and cleaning of surfaces exposed to corrosion,
– renewing insulating protective coatings (eg painting),
– modifying the composition of the environment (e.g. inhibitors),
– control and regulation of active electrochemical corrosion protection systems
To provide active protection against electrochemical corrosion, separate electrodes may be used, placed in a corrosion environment, or such metallic coatings that cause cathodic polarization of the protected metal or anodic polarization – in cases where the protected metal undergoes passivation. In the case when separate electrodes (cathodes or anodes) will be used, systems with permanent electrodes, powered from an external voltage source, or protectors – replaceable electrodes made of corrosive material in contact with protected metal (system without an external voltage source)
To conduct the galvanisation process, the elements should be thoroughly cleaned and degreased as part of their preparation for electrolysis. Then a galvanic bath is performed, which consists in immersing a given object in the electrolyte, which contains metal ions (galvanic bath). This will create a coating. The direct current that flows through the electrolyte causes the coating metal ions to settle on the galvanized part. The current used in the galvanisation process should have the right density. Therefore, it is very important not only the galvanic bath composition, but also the type of metal, the determination of appropriate additional parameters, current efficiency and electrolyte temperature. Our electrolytes ideally fulfill their functions, and the remaining accessories for galvanic baths make this process even more effective than before.
