Despite the widespread of industrial coverings (about 40% of all galvanic coverings fall at galvanization process), there are few studies about the application of nanocarbonic additives in this process.
Zinc is associated with a combination of resistance to the environment and low prices of inorganic zinc compounds. Its standard capacity is 0, 76 V in a significant negative potential of iron is 0, 40 V. Thus, being the anode against it, zinc performs an electrochemical protection.
Rising requirements to such settings have led to the creation of composite electrochemical coverings.
In this research we used A-1DM (by “Chemeta” company). This addition increases the cathodic polarization, changing the polarization curves towards negative potentials.
One of the rapidly developing ways for improving physical and chemical qualities of coverings is the use of dispersible materials. The addition of heterogenic particles to the electrolytic settings helps to create a composite electrochemical covering (CEC).
Nano diamonds are the composite additives of a new generation. They are much better than previous supplements and haven’t got any drawbacks. They are easily regenerated, evaluated and are environmentally friendly.
The main functional of zinc coating quality is the corrosion resistance, which increases when getting dense cryptocrystalline layers, which are usually got by a strong polarization changing to negative potentials. The introduction of nanodiamonds greatly helps to such shift and getting cryptocrystalline coverings.
