Abstract

"Pó METáLICO à BASE DE COBALTO E MéTODO PARA A PRODUçãO DOS MESMOS". A presente invenção refere-se a uma composição de pó metálico para produção de componentes de pó metálico compreendendo um pó pré-ligado à base de Co, com partículas de forma irregular compreendendo pelo menos 15% em peso de Cr e menos de 0,3% em peso de C, misturado com grafite. A invenção também se refere a um método para produção de componentes PM pressionando-se os artigos para se conformarem a partir da composição de pó metálico conforme a invenção e sinterizando-os."COBALT METAL POWDER AND METHOD FOR THE SAME PRODUCTION". The present invention relates to a metal powder composition for producing metal powder components comprising a pre-bonded Co-based powder having irregularly shaped particles comprising at least 15 wt% Cr and less than 0.3 % by weight of C mixed with graphite. The invention also relates to a method for producing PM components by pressing the articles to conform from the metallic powder composition according to the invention and sintering them.
