According to Walker [1997] and Norvell et. al [2007] clay content in the soil affects the rate of water absorption, as well as porosity and well recognised in their ability to absorb water and swell.
Weng et. al, [2003] stressed that; the capacity of water absorption is directly proportional to the amount and size of apparent porosity.

Abd El-Hafez [6] Implemented an experimental analysis to mechanical properties and welding power of friction stirred AA2024-T35 Joints.
FSW of Al alloys may provide high join efficiency in such structures but potential FSW defects must be understood.

The Zn and Al content were varied from 5.0 to 25.0 wt.% and 1.0 to 4.0 at.% respectively.
Fig.2 shows the effects of the Al content on the resistivity of Zn-coated T-ZnOW.
The minimum resistivity is 1520 Ω·cm when Al content is 2.0 at.% in Zn-coated T-ZnOW powders.
Wan et al reported that T-ZnOW powders treated by Al2O3 thermally in Zn vapor could form Al-doped T-ZnOW[10].
