Etching of metals

The micro channels were made by isotropic wet chemical etching of metal plates. The plates were tightened by various means they were either glued, stacked to-... [Pg.270]

The micro structured platelets, hold in a non-conducting housing, were realized by etching of metal foils and laser cutting techniques [69]. Owing to the small Nemst diffusion layer thickness, fast mass transfer between the electrodes is achievable. The electrode surface area normalized by cell volume amounts to 40 000 m m". This value clearly exceeds the specific surface areas of conventional mono- and bipolar cells of 10-100 m m. ... [Pg.413]

Core etching of metallic nanoparticles Here, the bigger metallic nanoparticles are etched into smaller clusters by selected molecules. [Pg.336]

In electrochemical etching of metals the plate and a counterelectrode are placed in a liquid electrolyte and a voltage is applied to create an electric field between the plates to dissolve the metal as soluble ions. Discuss the following issues and sketch configurations and profiles. [Pg.397]

The knowledge and control of localized corrosion was also required to produce etched plates for the graphic artist with its intaglio lines. Prints made by the process first appear around 1500 AD, but there was a long prehistory in the decorative etching of metal surfaces, particularly those of steel arms and armor [279]. [Pg.134]

Processing of CDC was recently reviewed by Nikitin and Gogotsi [28], Carbon derived from selective etching of metals by halogens has shown great promise as the active material in electrochemical capacitors [15,29-31] because of the structure and properties that can be fine-tuned [21,32] and control of surface functional groups [33],... [Pg.78]

To fabricate structures by electrochemical etching of metallic and semiconductor electrodes with high precision and accuracy. [Pg.272]

ELECTROLYTIC ETCHING OF metals produces various results intergranular attack, attack of crystalline surfaces which is orientation dependent formation of etch pits, and anodic oxide films. The behavior of a metal or alloy depends on composition, temperature of the electrolyte, and above all on the electrode potential which varies with the metal. Applications to Al, Fe, stainless steel, Ti, 2r, U, and their alloys will be discussed. [Pg.244]
