Abstract

The surface element deposition and corrosion behavior of AZ91D magnesium alloys multi-cut with high speed wire electrical discharge machine (WEDM-HS) is studied in this paper. The 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 resistance. Experimental results show that WEDM-HS multi-cutting process can effectively improve the surface integrity to obtain a flat surface. Carbon and oxygen of the foreign elements were observed after WEDM-HS cutting. Multi-cutting process increased the oxygen element content in the machined surface. The Multi-cutting surface exhibited excellent corrosion resistance property in the 3.5 wt. % NaCl solution.
