abstract: Surface modification is known to contribute immensely to the properties
8 of alloys. The motivation behind this present study is to develop a bath with quality
9 coating with targeted Zn–SnO2 reinforced Zn-based composite particulate produced
10 by electrolytic co-deposition route. The influence of SnO2 on Zn–13SnO2 sulphate
11 electrolyte on the properties of the nano-particulate coatings was investigated. SnO2
12 was varied from 0 to 16 wt%. The microchemistry and interfacial structural
13 properties were tested by X-ray diffraction (XRD), optical microscope, scanning
14 electron microscope (SEM) equipped with energy disperse spectrum (EDS). The
15 corrosion degradation properties in 3.65 % NaCl static solution at 40 °C were
16 characterized by high-resolution optical microscope (HR-OPM). The structure of
17 the conditioned composite coating indicates the presence of thin blend phase of
18 ZnSn2, Zn2Sn and Zn. The microstructure revealed good distribution of particulate
19 within the interface. The corrosion rate results properties shows 0.007786 mm/year
20 for Zn–7Sn–0.3 V–S. The study has established that up to 13 wt% SnO2 particulate
21 in bath on mild steel can be used in improving the structural and corrosion resis-
