  "description": "<p>The effect of the anode material on the rate of electrodeposition of Fe-W alloy coatings from a citrate bath is&nbsp;studied. Both Fe and Ni soluble anodes and Pt and graphite insoluble anodes are addressed. The effects&nbsp;associated with the anode material are attributed to anodic oxidation of an Fe(II)-citrate complex involved in&nbsp;electrodeposition. In addition to its likely oxidation at the anode, this complex catalyzes reduction of W-containing&nbsp;species and acts as precursor to Fe deposition; these processes unfold via the formation of&nbsp;corresponding intermediates, their surface coverage determining the alloy composition. X-ray photoelectron&nbsp;spectroscopy characterization of deposited alloys indicates that the intermediate FeOHads is oxidized by water&nbsp;to form surface oxides. This process can explain the previously reported macroscopic size effect, i.e., the effect&nbsp;of the volume current density on the microhardness of deposited alloys. By using a soluble iron anode, we&nbsp;achieve an unprecedentedly high rate of alloy de position (25 &mu;m/h at a current density of 20 mA/cm2).</p>",
