Folks,
We have a need to measure the corrosion rate of steel h-piles (A572) installed in corrosive soils. The h-piles support a stuctural wall. Other than excavating a few h-piles and taking physical measurements of the h-piles over time, and monitoring using resistance coupons, is the linear polarization resistance technique suitable for this environment and application. Most of the reading I've ran across seems to indicate LPR works best in liquid solutions, don't know how effective it would be in soils or dirt to determine the corrosion rate. LPR looks like it is more suited for processes at chemical or petroleum plants are enclosed in a piping system.
Anybody familiar with the LPR technique to measure and capture corrosion rate?
Thanks,
