Our present investigation focuses on the thermal stability of already developed electroforms of ZnANiudand ZnANiAAl2O3 thin films induced with triethylamine (TEA) and monoethylamine (MEA) as surfactantudby electrocodeposition on mild steel substrate with the aim to re-examine its micro-hardness anduddegradation behaviour in static sodium chloride solution. In the event, the samples were thermally treatedudat 200 �C and air cooled. The results obtained showed that the developed composites are thermallyudstable with hardness value of the ZnANiAAl2O3 coated; 185 Hv increased to 190.5 Hv indicating aud2.89% improvement. Noticeably, in the ZnANi coatings, a decrease in the hardness with 26.67% wasudobserved. The oxidation resistance was however favored for both composites.
