Abstract
Material compuesto para cojinetes autolubricantes de altas prestaciones y cojinete obtenido con el mismo. Este material tiene una matriz obtenida a partir de una mezcla de polvos metálicos compactada y sinterizada, comprendiendo un polvo con base de hierro o acero, uno o varios polvos de componentes aleantes, un lubricante de prensado y un lubricante sólido que es un sulfuro metálico térmicamente estable a las temperaturas de sinterización, participando en un 0,5% a un 15%, en peso, según las características mecánicas y tribológicas deseadas, no alcanzando la resistencia a la tracción del material un valor 6 veces inferior al esperado sin dicho lubricante sólido, operando bajo unas presiones de compactación de 200 a 1.000 MPa, con un agente ligante de todos los componentes y siendo la porosidad del material de un 1 a un 25% en volumen e impregnada con un lubricante mineral o sintético, tal como un aceite especial con aditivos de extrema presión y espesantes.Composite material for high performance self-lubricating bearings and bearing obtained therewith. This material has a matrix obtained from a mixture of compacted and sintered metal powders, comprising an iron or steel based powder, one or more alloying component powders, a pressing lubricant and a solid lubricant which is a thermally metallic metal sulphide. stable at sintering temperatures, participating in 0.5% to 15%, by weight, according to the desired mechanical and tribological characteristics, the tensile strength of the material not reaching a value 6 times lower than expected without said solid lubricant , operating under compaction pressures of 200 to 1,000 MPa, with a binding agent of all components and the porosity of the material being 1 to 25% by volume and impregnated with a mineral or synthetic lubricant, such as a special oil with extreme pressure additives and thickeners.
