Description

Pretende-se desenvolver um protótipo de um novo sistema de anéis vedantes dinâmicos (empanques mecânicos) fabricado com base num material compósito cerâmico: matrizes de nitreto de silício (Si3N4) reforçadas por partículas de carboneto de silício (SiC). Estes empanques destinam-se a aplicações hidráulicas e pneumáticas industriais em condições de alta pressão de contacto e elevada velocidade de deslizamento, particularmente na bombagem de líquidos e gases corrosivos. O Departamento de Engenharia Cerâmica da Universidade de Aveiro tem vindo a investigar há mais de uma década componentes cerâmicos para aplicações tribológicas à base de nitreto de silício, possuindo um conjunto vasto de técnicas necessárias para a produção à escala de protótipo deste tipo de materiais e respectiva caracterização microestrutural e mecânica. A parceria avançada na presente proposta assenta numa base de transferência tecnológica no domínio dos novos materiais cerâmicos, objecto de I&D nas principais empresas mundiais do sector das peças de desgaste, que permitirá o alargamento e actualização da oferta industrial da empresa DURIT.
