Corrosion Inhibitor Screening Test

Corrosion inhibitor screen testing

Purpose

1) Effectiveness of corrosion inhibitor in particular environment

2) Film persistency

Designed corrosion testing

1) General or uniform corrosion

2) Localised pitting /crevice corrosion

3) Stress corrosion cracking

laboratory corrosion measurement techniques

1) Direct metal loss measurement e.g. corrosion coupon method, iron count method

2) Indirect corrosion measurement, e.g. hydrogen evolution method, polarisation V-I curve method, film thickness measurement

3) Stress related failure

Key aspects of Corrosion inhibitor testing

1) Chemical compatibility

2) Chemical stability

3) Thermal stability

4) Physical stability

5) Transport phenomena
