Electrochemical testing - part 3- What does an ammeter do?

 Electrochemical testing - 3 - Ammeter

Poll Question WITH Answers:


Description:


Tafel polarization is a potentiodynamic test, where the potential is changed at a certain mV/time rate.


The changes in the current flow occurring due to the potential change are measured using the ammeter.

The ammeter is connected between the working electrode and the counter electrode.

It is NOT connected to the reference electrode in any way.

Important terms in API certifications - CRV & IOW - I

CRV stands for critical reliability variables. It notes the variables, i.e. parameters which are the most important in damaging the reliability of the equipment. In simple terms, it is that parameter which if changed will damage your equipment. This parameter is important in risk-based inspection. It helps to note the exact parameters, may be temperature, pressure, pH, which will increase the risk of corrosion and damage.

Outer walls/roof Atmospheric corrosion coating degradation due to moisture + UV radiation + temperature Erosion and wear due to wind and dust particles biological growth at the bottom areas near soil soil corrosion near the bottom 3. Pipes Atmospheric corrosion Coating degradation mechanical failure internal corrosion due to water/dissolved oxygen crevice corrosion in areas facing away from atmosphere corrosion at welds and joints microbial corrosion at 6 o' clock positions erosion corrosion at bends 4.
