Treść
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 (t(p)) and amplitude of current (I-A). 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. On the basis on obtained results it can be stated that there is possibility of shaping geometry of nano-Al2O3 doped and undoped FeAl sinters by WEDM. Reduction of the time of interval (t(p)) and increase of current amplitude (I-A) during WEDM deteriorate surface properties. Addition of nano-Al2O3 improve the quality of the obtained surface. Applied parameters of WEDM improve theoretical abrasive wear resistance and lubricant maintenance of the nanoceramic doped material in comparison with undoped sinter.
