Abstract
Yttria-stabilized tetragonal zircônia (Y_TZP) presents hydrotermal instability in low temperatures by the transformation of the tetragonal fase into monoclinic fase, leading to low temperature degradation (LTD) and possible impairment of mechanical properties. Inside the aid Jovem Pesquisador 2012/19078-7, in which this project inserts, some compositions of zirconia toughened alumina (ZTA…
