Composite self-lubricating bearings for high performance and bearing obtained therewith.

摘要

Composite self-lubricating bearings for high performance and bearing obtained therewith. This material has a matrix obtained from a mixture of compacted and sintered metal powders, comprising a base powder of iron or steel, one or more powders of alloying components, a lubricant pressing and a solid lubricant is a metal sulfide thermally stable at sintering temperatures, participating in a 0.5% to 15% by weight, according to the mechanical characteristics and desired tribological not reaching the tensile strength of the material 6 times a value lower than expected without said solid lubricant operating under a compaction pressures 200 to 1000 MPa, with a binding agent of all the components and being the porosity of the material 1 to 25% by volume and impregnated with a mineral or synthetic lubricant such as a special oil with extreme pressure additives and thickeners.
