Abstract
Method for manufacturing a machine housing having a fluid chamber (14) with a hardening layer (16) on an internal wall surface, in which the hardening layer (16) is made of a material, that, per-se, is not electrically conductive but has been made conductive by additives, and in that the surface of the hardening layer (16) is machined by electro-discharge machining.
Claims15
Method for manufacturing a machine housing having a fluid chamber with a hardening layer on an internal wall surface, comprising the steps of:
- making the hardening layer of a material, that, per-se, is not electrically conductive but has been made conductive by additive, and
- machining the surface of the hardening layer by electro-discharge machining (EDM).
Machine comprising a housing with a fluid chamber that has a hardening layer of silicon carbide on an internal wall surface thereof, and the silicon carbide includes additives that confer an electric conductivity to the silicon carbide sufficient for performing EDM.
