Impulse Laser Effect on Graphitized Surface of Y–TZP-Ceramics

详细

The role of a graphite layer on the surface of ceramics based on tetragonal zirconia, partially stabilized by yttrium oxide (Y–TZP-ceramics) under the action of a pulsed laser was studied using original methodology. It has been found that surface graphitization increases the fraction of absorbed laser radiation, and as a result, heating, melting and evaporation of Y–TZP-ceramics occur under less intense modes, favorably affecting the use of pulsed laser radiation for surface modification.
