Effect of Annealing Temperature of the Functional Nano Thin Films Synthesized on a Ceramic Substrate

초록

The insulation resistance of a ceramic insulator substrate decreases when contaminants are attached to its surface, and this can result in a spark flashover that can trigger accidents involving power transmission or power supply systems. To prevent such accidents, ceramic insulators have to be continually maintained and cleaned regularly. However, removing contaminants attached to ceramic insulators requires the use of much water and entails a high cost. Thus, the maximum washing efficacy with a minimum amount of water should be secured. The surface features of the object that will be washed are an important determinant of the washing capacity. In this study, ceramic insulators are coated with a nano-sized functional thin film by using the spray coating method. The coated ceramic insulators were annealed with an increase in temperature from 100 degrees C to 400 degrees C. Then, the surface features of the annealed ceramic insulators were analyzed, and the results of the experiment are presented.
