Abstract

MéTODOS PARA PRODUZIR PRODUTOS COMPACTADOS DE PóS à BASE DE FERRO COMPREENDENDO LUBRIFICANTE E COMPOSIçõES EM Pó QUE OS CONTéM. A invenção refere-se a um método para produção de produtos e a um pó à base de ferro grosseiro compreendendo um lubrificante com um ponto de fusão cristalino abaixo de 25<198>C, uma viscosidade (n) a 40<198>C acima de 15 mPa.s e, em que, a referida viscosidade é dependente da temperatura de acordo com a seguinte fórmula: 10 log <sym> = k/T + C, onde a inclinação k é preferencialmente acima de 800, T é a temperatura em Kelvin e C é uma constante, em uma quantidade de 0,05 - 0,4% em peso.
