Our present investigation focuses on the thermal stability of already developed electroforms of ZnANi
and ZnANiAAl2O3 thin films induced with triethylamine (TEA) and monoethylamine (MEA) as surfactant
by electrocodeposition on mild steel substrate with the aim to re-examine its micro-hardness and
degradation behaviour in static sodium chloride solution. In the event, the samples were thermally treated
at 200 �C and air cooled. The results obtained showed that the developed composites are thermally
stable with hardness value of the ZnANiAAl2O3 coated; 185 Hv increased to 190.5 Hv indicating a
2.89% improvement. Noticeably, in the ZnANi coatings, a decrease in the hardness with 26.67% was
observed. The oxidation resistance was however favored for both composites
