potentiodynamicadj.

Brit.

/pəˌtɛnʃɪə(ʊ)dʌɪˈnamɪk/, U.S.

/pəˌtɛn(t)ʃioʊˌdaɪˈnæmɪk/

Origin: Formed within English, by compounding. Etymons: potentio- comb. form, dynamic adj.

Etymology: < potentio- comb. form + dynamic adj.

Physical Chemistry.

Relating to or involving controlled variation of the current passing through an electrolyte, typically used as a means of studying the kinetics of electrochemical reactions. Cf. potentiostatic adj.

1963 Electrochimica Acta 8 521 The measurements were carried out with a potentiodynamic apparatus, with potential varied at 2V/hr.

1982 Nature 13 May 113/2 Whilst this approach may be more reliable than potentiostatic or potentiodynamic methods when small current densities are applied, concentration polarization distorts anodic behaviour.

1991 Nucl. Energy June 183/2 A potentiodynamic technique..was used to construct the polarization curves at a scan rate of 1 mV/s.

1998 Power Engin. (Nexis) July 29 Tests were conducted for 18 hours and corrosion rates were determined electrochemically from potentiodynamic polarization resistance measurements.
