Abstract

Patente de Invenção<B>"METALURGIA DO Pó, DE ARTIGOS BASEADOS EM COBALTO TENDO ALTA RESISTêNCIA AO ARTIGO E CORROSãO EM METAIS SEMI-SóLIDOS"<D>. Artigo de pó metálico a base de cobalto completamente denso, que tem uma alta resistência a atrito e corrosão para um metal semi-sólido. O artigo tem uma composição constituinte de C em uma quantidade de aproximadamente 0.65 até menos do que aproximadamente 1%, W em uma quantidade de aproximadamente 3 até aproximadamente 5%, Cr em uma quantidade de aproximadamente 25 até aproximadamente 30%, Co em uma quantidade compreendendo principalmente o balanceamento do artigo. O artigo tem uma dureza maior do que 42HRC e mais preferivelmente 45 HRC, uma resistência a fratura por flexão maior do que 2,275 MPa (330 ksi) e uma substancial estabilidade de propriedade dimensional e mecânica durante a exposição a temperaturas na faixa de aproximadamente 593°C a 816°C (1100°F a 1500°F).
