Effect of extrusion mode on the corrosion and anodic discharge behavior of Mg-6Al-0.3Mn-0.6La
Source abstract
Abstract
On the basis of aging heat treatment, the effects of two extrusion methods on the electrochemical and discharge performance of AM60-0.6La alloy were investigated. Conventional extrusion (CE) and turning bearing extrusion (TBE) can fine the grain size of AM60-0.6La compared with the as cast state. AM60-0.6La (TBE) produced fine precipitates (Mg17Al12 and Al2La) in the whole alpha-Mg matrix. These fine uniform precipitates caused less the micro-galvanic coupling and increased the corrosion resistance. EBSD showed that the crystal faces of the AM60-0.6La (TBE) processed AM60-0.6La had lower surface energy, which also indicated a lower corrosion rate. The best discharge performance of AM60-0.6La (TBE) was attributed to the fine grains and dispersive secondary phase particles, which enhanced the discharge activity. Because of the existence of small "honeycomb" holes on the surface, discharge products would spontaneously fall off during discharge. When current density was 10 mA center dot cm-2, AM60-0.6La (TBE) alloy exhibited the best average discharge voltage of 1.32 V, and anodic efficiency of 62.7 %.
