abstract = {Transparent polycrystalline ceramics have the potential to
enable applications no other materials can, but to do so
their strength and toughness must be improved. However,
surface strengthening treatments like those used for glasses
have so far remained elusive. Here for the first time, we
report on engineering unprecedented surface compression, of
the magnitude achieved for ion-exchange strengthened glasses
(~750 MPa) in transparent ceramics. This was achieved by
applying functional, low thermal-expansion yttria coatings
onto yttria-stabilized zirconia substrates and thermally
treating. In some instances, the treatment more than doubled
the fracture toughness while simultaneously increasing light
transmittance.},
