摘要:The surface element deposition and corrosion behavior of AZ91 D magnesium alloys multi-cut with high speed wire electrical discharge machine(WEDM-HS) is studied in this paperThe microstructure and surface morphology of the WEDM-HS surfaces were examined with scanning electron microscope(SEM)Chemical composition of the fabricated surface was analyzed by energy-dispersive X-ray spectroscope(EDS)Using Tafel polarization curves to evaluate the corrosion resistanceExperimental results show that WEDM-HS multi-cutting process can effectively improve the surface integrity to obtain a flat surfaceCarbon and oxygen of the foreign elements were observed after WEDM-HS cuttingMulti-cutting process increased the oxygen element content in the machined surfaceThe Multi-cutting surface exhibited excellent corrosion resistance property in the 3.5 wt% Na Cl solution.
