Preparação e caracterização de materiais compósitos SiC/caulim/Al via "squeeze-casting"

Abstract: Na busca de materiais com propriedades diferenciadas, vem aumentando nos últimos anos as pesquisas em materiais compósitos. Um dos importantes métodos de fabricação destes compósitos é o processo de infiltração sob pressão de metal fundido denominado "squeeze-casting". Este processo oferece algumas vantagens, tais como facilidade de produzir o compósito, baixo custo e capacidade de formação de estruturas em rede. Neste trabalho foram produzidos e caracterizados compósitos SiC-Al, com concentrações em caulim va… Show more
