## Description

- description: Corrosion of the steel reinforcing bar (Rebar) reduces the strength
    capacity of concrete structures. Corrosion detection at the early stage of steel
    rebar is important for the maintenance of concrete structures. Using the eddy
    current testing method, we developed a portable system to evaluate the corrosion
    of steel rebar. An AC current was sent to the excitation coil to produce the AC
    magnetic field and eddy current was induced in the steel rebar. A detection coil
    was used to detect the signal produced by the eddy current. A lock-in amplifier
    was used to get the same phase signal and 90-degree phase difference signal and
    X-Y graph was plotted. From the slope of the X-Y graph, the corrosion of steel
    rebar or steel wire can be evaluated.  In order to optimize the system, we examined
    the effects of excitation frequency, coil type and coil size on the experimental
    results. With a specially designed probe, the signal-to-noise ratio and the detection
    depth were improved.
