Effect of Electron Beam Treatment on the Surface Properties of AZ31B Magnesium Alloy

Abstract:

AZ31B magnesium alloy were irradiated by a high current pulsed electron beam (HCPEB) device with pulse times 10, 15 and 20 respectively. The morphology of the surface and cross-section of modified layer were investigated by optical microscope. The corrosion resistance of modified layer were tested by EG&G M273 potentiostat in 5% NaCl solution. Wear resistance were tested by HRS-2 high speed reciprocation frictional testing machines. The results indicated that magnesium alloy surface hardness obviously enhances, the wear volume reduces 7%, the corrosion resistance also improves obviously after electron beam processing.
