It will facilitate the abrasion of the magnesium alloy surface during rubbing process and thus results in the worse anti-wear property. This was confirmed by the poor anti-wear behaviors of the samples with high concentrations of nano-SiO 2 , such as SiO 2 /MoS 2 (0.5:0.5), SiO 2 /MoS 2 (0.75:0.25) and pure nano-SiO 2 as shown in Fig. 3a .

The QE22 alloy should serve as a reference, as no thermal mismatch stress (TMS) will be present. However, the alloy is taken from the un-reinforced part of the squeeze cast MMC. Hence, it may be argued that some residual stresses might be present in the alloy arising from processing, which upon heating during thermal cycling will be relieved and will change the strain and CTE values and give
