Abstract

The article aims to develop a new processing technique to efficiently improve the corrosion resistance of Mg-alloy, thus ultrasonic surface rolling process (USRP) was applied to modify the corrosion resistance of extruded AZ31B Mg-alloy. The grain size and surface morphology as well as the corrosion behavior of AZ31B Mg-alloy before and after ultrasonic surface rolling were comparatively examined by means of metallomicroscope and scanning electron microscopy, white light interferometer and electrochemical impedance spectroscopy. The results implied that USRP has significant influence on the grain size and surface morphology, in turn it has important influence on the corrosion behavior of AZ31B alloy. Compared with the bare alloy, the corrosion product film on USRPed alloy was much uniform and dense, while after removal of the corrosion products, small and dense corrosion pits could be seen on the Mg-alloy surface. The passivation film resistance (R_f=9020 Ω) of the treated alloy was much larger than that (R_f=14.8 Ω) of the bare alloy in the early stage of immersion. The impedance characteristic caused by the diffusion process appeared on the impedance spectrum of the bare alloy in the middle of immersion. At this time, the film resistance R_f=22.9 Ω, which is much smaller than the film resistance R_f=19800 Ω of the USRPed alloy. In the late stage of immersion, the passivation film resistance was R_f=31400 Ω for the USRPed alloy, while R_f=14400 Ω for the bare Mg-alloy. It follows that the ultrasonic surface rolling process could reduce the surface roughness, and refine the grains of Mg-alloy, thus increase the uniformity and compactness of passivation film on Mg-alloy, namely retard the electrochemical reaction process on the alloy surface, therewith reduce the occurrence of local pitting, then reduce the corrosion rate of Mg-alloy.
