Abstract
Laser induced surface modification has been carried out in commercially available lead zirconate titanate (PZT) ceramics for the potential use in microelectronics and microsystem technology applications. The modification of surface has been achieved by the localized remelting of PbO precoated PZT substrate, using infrared laser irradiation of CO2, followed by solidification of the alloyed surface. PZT has been found to evaporate as PbO during its remelting, leading to a significant loss of the material. Precoating of PbO on the PZT substrate has been observed to compensate this material loss. The microstructures of the laser-modified surfaces have been studied with X-ray diffraction, scanning electron microscopy and energy dispersive X-ray analysis.
