Electrochemical quartz crystal microbalance study of high-rate Pt dissolution in H2O2-containing H2SO4 solution with Fe2+ ion

International Journal of Hydrogen Energy, 2016
Abstract Pt dissolution in an H2SO4 solution was investigated in the presence of both H2O2 and Fe2+ using an electrochemical quartz crystal microbalance (EQCM). The EQCM data in the H2O2-containing H2SO4 with and without Fe2+ showed that a remarkable Pt dissolution occurred during the cathodic potential step of 1.36 → 0.36 V vs.

Role of Hydrodynamic Conditions in the Distribution of Anodic Dissolution Rates in Cavity Etching Regions during Electrochemical Micromachining of Partially Insulated Surfaces

Russian Journal of Electrochemistry, 2003
Experimental study of the distribution of local rates of electrochemical micromachining in the presence of photoresist masks in various hydrodynamic conditions (macroscopically nonuniform rotating disk electrode, sprayer flow, an electrode placed into a cell with chaotic bulk electrolyte mixing) shows that the maximum etching localization is achieved ...

Electrochemical interfacial phenomena under microgravity: Part 2. Numerical analysis of the rate of ionic mass transfer accompanying anodic copper dissolution

Metallurgical and Materials Transactions B, 1999
The anodic dissolution phenomena of copper, under microgravity in a drop shaft, was compared to that in terrestrial experiments. A 0.1 M CuSO4-1 M H2SO4 solution layer was confined to a shallow (200-μm-thick) and horizontally installed electrolytic cell.

Determination of the rate of electrochemical dissolution of U10A steel under ECM conditions with a stationary cathode-tool

Metal Working and Material Science
Introduction. In blank production, when replacing hard alloys with tool steels, difficulties arise in shaping surfaces to ensure the required parameters of productivity, quality and accuracy, due to the presence of incomplete information for assigning electrochemical processing modes for this class of materials.
