Description
In this study, we report the effect of Solanum tuberosum (ST) as a strong
additive on the morphological interaction, wear, and hardness properties of electroplated
zinc coating in chloride bath solutions. The structural and the mechanical
behavior of the Zn–Al–ST coating were studied and compared with the properties of
Zn coatings. Characterization of the electrodeposited coatings were carried out
using scanning electron microscopy, energy dispersive spectrometer, AFM, and
X-ray diffraction techniques. The adhesion between the coatings and substrate was
examined mechanically using hardness and wear techniques. From the results,
amorphous Zn–Al–ST coatings were effectively obtained by electrodeposition using
direct current. The coating morphology was revealed to be reliant on the bath
composition containing strong leveling additives. From all indications, ST content
contribute to a strong interfacial surface effect leading to crack-free and better
morphology, good hardness properties, and improved wear resistance due to the
precipitation of Zn2Si and Zn7Al2Si3. Hence, addition of ST is beneficial for the
structural strengthening, hardness, and wear resistance properties of such coatings.
