Influence of the Current Regime during Electrodeposition in a Cr(III)-Containing Fe-Cr-Ni Electrolyte on the Near-Surface pH, Alloy Composition, and Microcrack Behavior

This study shows the electrodeposition of Fe-Cr-Ni alloys using advantages a stepped direct-current deposition in Cr(III)-containing electrolyte, and its influence on pH value. The resulting coatings are uniform free microcracks, with Cr content around 30% thicknesses above 10 µm. current mode (direct current, direct pulsed current) development is investigated correlated arising microstructure alloy composition. Considering flow, it can be stated that pauses interrupt high overvoltage restrain increase at cathode. associated formation chromium hydrides their onto layer, leading to cracking, thus reduced. In this work, evidence for theory suggestion near-surface measurement during presented.
