Efeitos das variáveis de formulação de suspensões sobre o comportamento reologico e sobre a microestrutura de filmes cerâmicos NiO-YSZ

Abstract: A preparação de filme cerâmico granular compósito NiO-YSZ por deposição a jato de suspensão exige rigoroso controle das variáveis de processamento, especialmente a reologia da suspensão devido sua importância tanto na viabilização do processo de deposição como na definição da microestrutura do filme final. Neste trabalho foi estudado como as variáveis de formulação da suspensão afetam sua viscosidade e a microestrutura do filme granular. Foram escolhidas seis variáveis de formulação: teor de sólidos, razão em … Show more

“…In the fuel cell, the reaction of hydrogen (H 2 ) with oxygen (O 2 ) generates water and energy. From the point of view of the current global economy, two major challenges of the 21st century can be solved: clean energy generation and water generation . However, this technology is still being developed on a smaller scale for commercial purposes due to high costs of existing energy generation technologies.…”
