Dureza e módulo de elasticidade em cerâmicas multifásicas

Dureza e módulo de elasticidade em cerâmicas multifásicas

Abstract

O problema proposto consiste em elucidar se a contribuição de cada fase para propriedades como a dureza e o módulo de elasticidade em compósitos cerâmicos multifásicos CaZrO3-MgO-ZrO2 podem ser estimados com base em modelos simples como a “regra das misturas” ou se existem outros fatores para levar em consideração tais como o tamanho, a forma e os limites de grão. Assim, as propriedades de dois materiais previamente desenvolvidos [10-12], com as mesmas fases principais (CaZrO3, MgO e c-ZrO2), mas em diferentes frações volumétricas e tamanho de grão foram analisadas de modo a cumprir as seguintes tarefas: i) Determinar a dureza de cada material usando macro indentação; ii) Determinar a dureza e o módulo de elasticidade de cada uma das fases principais por nano indentação; iii) Verificar a independência das fases constituintes face aos dois materiais e comparar os resultados obtidos com os descritos na literatura; iv) Determinar a contribuição esperada de cada uma das fases para as propriedades da cerâmica multifásica (compósito).
