SEQUENCER SYSTEM FOR DATA COLLECTION OF CORROSION SPECIMENS

摘要

The sequencer system for corrosion data collection of specimens includes a container for holding a plurality of specimens to be tested. During testing, the container holds a solution bath. A reference electrode and a counter electrode are coupled to a potentiostat, both electrodes being operationally disposed inside the container. A sequencer is connected to each specimen via a working electrode line. The sequencer operates in concert with the potentiostat to switch between a tested specimen and a subsequent specimen to be tested during a pause phase between each polarization cycle of the potentiostat. A computer is coupled to the potentiostat and the sequencer, and a program controls synchronized operations between the potentiostat and the sequencer. The program also permits automatic data collection for each of the specimens.

主权项

1. A sequencer system for corrosion data collection of specimens, comprising:
a container adapted to hold a plurality of specimens and a solution bath therein; a reference electrode disposed near one inner side of the container; a counter electrode disposed near another inner side of the container, the plurality of specimens being placed between the reference electrode and the counter electrode during a testing session; a potentiostat coupled to the reference electrode and the counter electrode, the potentiostat facilitating a plurality of polarization cycles during the testing session; a sequencer coupled to each of the specimens, the sequencer selectively switching connection to specimens between each polarization cycle of the potentiostat; and a computer coupled to the potentiostat and the sequencer, the computer having a program for controlling synchronized operations of the potentiostat and the sequencer to thereby obtain data from each specimen during a single testing session.
