Abstract: The process: includes mixing a metallic powder including iron or nickel or copper or mixtures of two or three elements thereof where the sum thereof defines at least 55% in mass of the metal matrix of the component to be produced, and a molybdenum disulfide powder as a densification agent and as a solid lubricant with a content from 3 to 30% in volume; filling a mold with the mixture and obtaining a compact presenting from 5 to 25% in volume of primary pores; and subjecting the compact to a temperature and time sufficient to allow the reaction of the molybdenum disulfide with the matrix, forming iron sulfide, nickel sulfide or copper sulfide, and the diffusion of the molybdenum in the matrix; and subjecting the compact to temperature sufficient to transform the sulfide into a liquid phase, filling the primary pores before finishing the sintering step of the compact.

Abstract: Manufacturing a porous component used as flow restrictor includes a metal injection molding process enhanced to obtain a component with open porosity homogeneously distributed. The flow restrictor includes at least one porous component having at least one restricting portion with some porosity dimensioned to regulate the flow of gas to an aerostatic bearing of a mechanical system, such as a hermetic compressor. Use and production of a porous component obtained by powder injection molding or powder injection molding of multi-material parts is also described, the porous component being a flow restrictor with a layer of dense material, with no open pores, on the outer surface parallel to the flow direction in which the flow through the porous component occurs, allowing it to be inserted into the bearing system without interfering with the porous structure of the core (dual porosity). Sealing existing between the porous component and its housing is described.
