摘要: The corrosion behavior and microstructure of hot extruded Mg-5 wt.%Sn-4 wt.%Al-2 wt.%Ce alloy by rapid solidification ribbon (RS-EX TAE542) are investigated. The results shows that corrosion resistance of RS-EX alloy is remarkably improved, compared with that of hot extruded TAE542 alloy by homogenized ingot (HI-EX TAE542). Relatively compact corrosion products and bedded corrosion surface of RS-EX alloy is connected with the fine grains and uniform particles caused by rapid solidification, and they can suppress the corrosion reactions.
