Paper Abstract

Dense yttria stabilized zirconia(YSZ) coatings have been prepared by the sol-gel method with zirconium oxychioride as a precursor. By controlling the processes and conditions, the coatings on the porous zirconia substrate are crack-free, have appropriate thickness and e. When exposing the surface of zirconia coatings to Lasers, changes of contact angles between water and the exposed surface are found. The crystalline structure of yttria stabilized zirconia are identified by X-ray diffraction (XRD); the morphology of coatings are observed by scanning electron microscope (SEM); the contact angels between surfaces and oil (or water) are measured by contact angel measuring system, It is shown that the contact angels of exposed surface of YSZ coatings increase significantly.
