Abstract

PEçAS METáLICAS SINTERIZADAS E MéTODO PARA SUA FABRICAçãO. A presente invenção refere-se a um método consistindo das etapas de fornecer um pá metálico à base de ferro pré-ligado compreendendo pelo menos 1,3-3,5% de cromo, 0,15-0,7% de molibdênio, manganês e as inevitáveis impurezas, misturar o mencionado pó com 0,1-1,0% de grafite, compactar a mistura obtida a uma pressão de pelo menos 600 MPa, sinterizar a peça compactada em uma única etapa a uma temperatura acima de 1 100<198>C, encruar por jato percussão a peça e após a sinterização opcionalmente endurecer o componente. A invenção também refere-se a uma peça de pá metalúrgico e ao uso de um pó pré-ligado de baixo cromo para preparação de peças sinterizadas entalhadas tendo um limite de fadiga de pelo menos 340 MPa a uma densidade de 7,15 g/cm¬ 3¬, preferivelmente pelo menos 400 MPa a uma densidade sinterizada de 7,3 g/cm¬ 3¬.SINTERED METAL PARTS AND METHOD FOR THEIR MANUFACTURING. The present invention relates to a method consisting of the steps of providing a pre-alloyed iron-based metal shovel comprising at least 1.3-3.5% chromium, 0.15-0.7% molybdenum, manganese and the unavoidable impurities, mix said powder with 0.1-1.0% graphite, compact the obtained mixture at a pressure of at least 600 MPa, sinter the compacted piece in a single step at a temperature above 1,100 ° C. 198> C, harden the part percussion and after sintering optionally harden the component. The invention also relates to a metallurgical shovel piece and the use of a low chromium pre-alloy powder for preparation of notched sintered parts having a fatigue limit of at least 340 MPa at a density of 7.15 g / cm ¬ 3¬, preferably at least 400 MPa at a sintered density of 7.3 g / cm¬ 3¬.
