Abstract
High purity iron-zinc intermetallic calibration standards are produced using a slow diffusion technique. The alloys are pure to greater than 99.5 wt % and are homogenous to greater than 98%. The alloys can be used to calibrate instrumentation used to monitor and measure galvanneal and galvanized coatings. The alloy calibration standards for each of the iron-zinc phases allows instrumentation correction factors to be determined for iron-zinc coating analysis.
