MECHANICAL PROPERTIES OF BORON-DOPED-ZINC OXIDE THIN FILMS USING SPRAY PYROLYSIS TECHNIQUE

Abstract

This study aims to establish the mechanical properties of boron-doped Zinc Oxide (ZnO) thin film. Mechanical properties are important for engineering applications and are a focus of engineering materials. Using the spray pyrolysis process, a thin coating of boron-doped (ZnO) is created on a soda lime glass substrate at a variable percentage. An iron-constantan thermocouple was used to monitor the substrate's temperature while the film was being deposited at different temperatures. Metallurgical microscopy was used to determine the mechanical characteristics of the doped and undoped samples, including hardness, impact, and tensile strength. The results indicated that when zinc oxide is doped, variations in impact and hardness values are detected, and maximum stress increases with dopant concentration. However, when zinc oxide is undoped, stress and hardness increase with temperature.
