20110108059 | PLASMA PROCESS AND REACTOR FOR TREATING METALLIC PIECES - The plasma reactor defines a reaction chamber provided with a support for the metallic pieces and an anode-cathode system, and a heating means is mounted externally to said plasma reactor. The plasma process, for a cleaning operation, includes the steps of connecting the support to the grounded anode and the cathode to a negative potential of a power source; feeding an ionizable gaseous charge into the reaction chamber and heating the latter at vaporization temperatures of piece contaminants; applying an electrical discharge to the cathode; and providing the exhaustion of the gaseous charge and contaminants. A subsequent heat treatment includes the steps of: inverting the energization polarity of the anode-cathode system; feeding a new gaseous charge to the reaction chamber and maintaining it heated; applying an electrical discharge to the cathode; and exhausting the gaseous charge from the reaction chamber. | 05-12-2011 |

20150266094 | MANUFACTURING PROCESS OF A POROUS COMPONENT AND A POROUS COMPONENT - 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. | 09-24-2015 |
