The research concerns an electrodeposited cobalt-tungsten alloy coating ongraphite fibers. Annealed and unannealed coated fibers were analyzed by scanning electron microscopy/energy dispersive x-ray spectroscopy (SEM/EDS), x-ray diffraction (XRD), and transmission electron microscopy (TEM). The mole fraction of tungsten in the as-deposited cobalt-tungsten coating was found to be (7.10 plus or minus 0.82) %, and the crystalline lattice was determined to be hexagonal closepacked. Note: The uncertainties reported here are expanded uncertainties (i.e., 2 standard deviation estimates).
