processo para a fabricação de rolamentos deslizantes de sinterizados

摘要

The present invention provides a process for manufacturing sintered sliding bearings by means of a powder metallurgy process. The process is characterised by including a porous surface coating (5) of soft metal in the central hole of the coupling matrix of the shaft (2), such that the sealing by plastic deformation of the pores (7) of the coating is facilitated.
