Multipass friction stir processing (FSP) can result in a homogeneous microstructure and significant improvement in mechanicalproperties of magnesium alloys. Few studies have concentrated on the surface properties of Mg–Zn–Zr alloy duringmultipass FSP. The aim of this study was to investigate the microstructure evolutions as well as the effects on the surfacecorrosion and wear resistance of ZK60 plates during multipass FSP. An interesting finding is that FSP can significantly refinethe grains and improve the surface properties of ZK60 alloy. However, subsequent passes of FSP cannot further reduce thegrain size in the stir zone, but they cause an increase in the grain size in the ZK60 alloy. In addition, the subsequent passesof FSP are not beneficial, but rather are, harmful to the corrosion resistance of ZK60 alloy. There is little positive effect onthe improvement in the wear resistance of ZK60 plates.
