1. A sensor for monitoring erosion and corrosion of a substrate, comprising:

  • a first element of corrosion resistant material having similar erosion properties to the substrate; and

    a second element of material having similar erosion and corrosion properties to the substrate;

    wherein said sensor provides an erosion indicator based at least in part on erosion of said first element and provides a corrosion indicator based at least in part on erosion and corrosion of said second element, said corrosion indicator based on a comparison of the erosion of said first element and the erosion and corrosion of said second element, wherein said first element and said second element are planar and are disposed on a surface of the substrate.
