Abstract

"LIGA COMPREENDENDO CROMO, PROCESSO DE ELABORAçãO DA MESMA E ARTIGO". A presente invenção se refere a uma liga compreendendo o cromo Cr~ 2~O~ 3~-formador, resistente à oxidação e/ou à corrosão notadamente pelo vidro, particularmente em alta temperatura, caracaterizada pelo fato de que ela contém, em dispersão, por meio de uma matriz, óxido de cromo Cr~ 2~O~ 3~ ou um precursor deste óxido. Esta liga pode ser preparada por metalurgia dos pós de acordo com um processo que compreende uma etapa de consolidação a quente de pós metálicos, notadamente sinterização. Aplicação a artigos utilizáveis em meio oxidante ou corrosivo em alta temperatura.
