Wire Electrical Discharge Machining Of Feal Intermetallic Sinters Without And With Addition Of Nano-Al2O3 Oxide Ceramic

Abstract

The influence of the parameters of wire electrical discharge machining (WEDM) on the surface layer of FeAl based sinters with and without Al2O3 nanoceramic addition has been studied in this paper. The properties of the sinters surface layer were controlled by WEDM parameters, including time of interval (tp) and amplitude of current (IA). The WEDM roughing and finishing treatments were carried out for selected technological parameters of process. The surface texture (ST) of the sinters after WEDM was analyzed by profilometer method. Theoretical parameters describing abrasive wear resistance of investigated sinters were estimated on the basis on the load capacity curve.
