PROCEDE ET ENSEMBLE DE PRODUCTION D'UNE PIECE MECANIQUE PAR FRITTAGE D'UN MATERIAU PULVERULENT

摘要

A method and an assembly for production of a mechanical component by sintering a pulverulent material, the method including: providing a pulverulent metallic material including grains, the pulverulent metallic material having a determined melting temperature; agglomerating a given quantity of the pulverulent metallic material under pressure inside a cavity; providing thermal energy to the given quantity of pulverulent metallic material to bring it to a given temperature below the melting temperature; and shocking the given quantity of agglomerated pulverulent metallic material and brought to the given temperature to bind the grains of the pulverulent metallic material to each other to obtain one solid body. The one solid body is thus maintained under pressure and thermal energy accumulated in the solid body is made to dissipate to obtain the mechanical component.
