The strength of glasses increases during an ion exchange experiment because of the significant surface compression that arises from the replacement of larger alkali ions into the smaller host alkali ion site. The application of an external energy source, such as an electric field, has the potential to enhance the efficiency of the ion exchange process. This study examines the enhancement of the mechanical strength of soda-lime glasses through the utilization of the electric field-assisted ion exchange technique. The objective of this study was to examine the effects of temperature, time, and electric field on enhancing the strength of the raw glasses. The sample exhibits the greatest strength and highest hardness number when subjected to a temperature of 400 °C and an electric field intensity of 2000 V/cm for a duration of 10 minutes. The results indicate that the samples exhibited a strength that exceeded four times the initial strength of the raw sample. Additionally, there was an observed increase in the hardness of the samples, with values ranging from 550±50 kgf/mm2 to 750±50 kgf/mm2. Furthermore, it has been observed that the case depth has attained a magnitude of 11 μm in specimens subjected to an electric field strength of 2000 V/cm for a mere duration of 10 minutes while being maintained at a temperature of 400 °C. Notably, in the absence of an electric field, the chemically tempered samples exhibit a depth of 3 micrometers at temperature settings of 400 °C for a duration of 240 minutes.
