Abstract
Thermally conducting paths are fabricated in commercially available lead zirconate titanate, PbZr0.5Ti0.5O3, ceramics by CO2-laser-induced surface modification in it with PbO precoating. Microstructures of the laser-modified surfaces are studied with optical microscopy, x-ray diffraction (XRD), and scanning electron microscopy, and the thermal conductivity is measured by photothermal method. XRD study indicates the retention of tetragonal phase in PbZr0.5Ti0.5O3, after the laser treatment with PbO precoating. Additionally, a second phase of tetragonal PbO develops in PbZr0.5Ti0.5O3 after the laser processing. Thermal conductivity of PbO precoated and laser treated PbZr0.5Ti0.5O3 shows an enhanced value (0.017W∕cmK) in comparison with that with laser treated PbZr0.5Ti0.5O3 (0.011W∕cmK).
