Abstract

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.
