Impulse laser effect on graphitized surface of Y‒TZP-ceramics

Using the original technique, the role of the graphite layer under impulse laser effect on the surface of ceramics based on tetragonal zirconia, partially stabilized by yttrium oxide (Y‒TZP-ceramics), was studied. It has been established that surface graphitization increases the fraction of absorbed laser radiation, as a result of which heating, melting and evaporation of Y‒TZP-ceramics occur under less intense modes, which favorably affects the use of impulse laser radiation to modify its surface.
