Abstract
We report on electrochemical and electron microscope investigations of Zn--12% Ni alloys, electrodeposited on steel. We recorded current transients after potential jumps from the open circuit potential to more noble potentials. For potentials below -0.65 V vs sce the transients have a negative slope, while at higher potentials this slope is positive. Hence, a critical potential of -0.65 V exists for this material. Up to this potential, nickel enrichment in the surface leads to a current decrease with time. Above -0.65 V more localized attack occurs, as can be seen from scanning electron micrographs. They indicate some grain boundary etching below and severe transgranular cracking above the critical potential.
Microsoft is Ending Support for Windows 7
Microsoft will discontinue support for Windows 7 on January 14, 2020 which means Gamry will also be discontinuing support for Windows 7.
