Abstract

In this, study the influence of high power Nd: YAG laser irradiation on the hardness and surface properties of zirconium silicate (ZrSiO4) ceramics was investigated. Specimens of zirconium silicate (ZrSiO4) ceramic pieces were separated into four samples according to irradiation duration as follows: one control sample (no treatment), and three samples irradiated with Nd: YAG laser at irradiation times 3, 4 and 5 minutes. The irradiation was applied with fixed output power 60 W. The hardness and tensile strength were measured and the optical properties were characterized by UV-vis spectroscopy, also EDX spectra was carried uot. The present results show that high power (60 W) Nd:YAG laser provide higher hardness compared to non-treated surfaces. Extending irradiation time can induce higher hardness of the ceramics. EDX results reveal that laser irradiation does not change the chemical surface composition of ceramics. Moreover, Increase in transmittance of the irradiated zirconium silicate in the visible and near infrared range was also found using UV-vis spectroscopy.
