Desenvolvimento da microestrutura do BaCeO3 dopado com ítrio sob a influência do ZnO como aditivo de sinterização: correlação com a condutividade protônica
(Universidade Federal de São Carlos, 2013-12-13)
Yttrium-doped barium cerate perovskites are promising electrolyte for solid oxide fuel cell (SOFC) due to high proton conductivity at intermediate temperature, 400-600°C. However, the proton conductivity is not an intrinsic ...
Efeito da precipitação de fase secundária na resistência à corrosão da superliga UNS N26455
(Universidade Federal de São Carlos, 2013-10-18)
The UNS N26455 is a superalloy of the Ni-Cr-Mo system used on offshore platforms as components of injection pumps. This alloy has low-carbon content and high levels of Cr and Mo. This composition gives the material high ...
