Changes in the surface structure of nickel substrates at open circuit in 75 weight percent(w/o) [H3PO4] after an etch treatment have been investigated by electrode potential measurements as a function of time, by voltametric repassivation in neutral sulfate solution, and by microscopic examination. The rate of depassivation is found to depend on the crystal orientation and the presence of impurities in the substrate. 1, record 1, English, - depassivation

Cette limite d'acidité est caractérisée par son pH, que l'on appelle pH de dépassivation, et qui peut être utilisé comme critère de classement de la résistance à la corrosion caverneuse des aciers inoxydables: plus le pH de dépassivation est faible, plus la résistance à la corrosion caverneuse est élevée. 1, record 1, French, - d%C3%A9passivation

Les composants de ces deux dernières piles à combustible (PAFC et PEMFC) sont très semblables, sauf pour ce qui est de l'électrolyte. Dans le cas de la PAFC, l'électrolyte est de l'acide phosphorique (aussi un électrolyte conducteur de protons), un liquide, alors qu'il s'agit d'un polymère solide dans le cas de la PEMFC. 5, record 2, French, - pile%20%C3%A0%20acide%20phosphorique

Les avantages de la PAFC sont sa facilité de fabrication, sa stabilité thermique et chimique et la faible volatilité de l'électrolyte aux températures de fonctionnement (entre 150 et 220 °C). 5, record 2, French, - pile%20%C3%A0%20acide%20phosphorique

In a previous study... I was able to demonstrate resin tags up to 50 um in length projecting into enamel surfaces etched with 50 % H3PO4 for 1 minute. It is quite conceivable that these filamentous tags will fracture and remain embedded in the enamel during the breaking of experimental bonds. 1, record 3, English, - resin%20tag

In addition to the familiar molecular acids, two classes of ionic acids emerge from the new definition [Bronsted-Lowry]. The first comprises anions derived from acids containing more than one acidic hydrogen; e. g., the bisulfate ion... derived from phosphoric acid(H3PO4). The second... consists of positively charged ions(cations), such as the ammonium ion... 1, record 4, English, - acidic%20hydrogen
