Electrochemical Studies for Material Selection & Corrosion Behaviour

Electrochemical Studies are specialized investigations used to evaluate corrosion behaviour, degradation mechanisms, and material performance in aggressive service environments. These studies provide quantitative and qualitative insights into corrosion rates, electrochemical reactions, and the effectiveness of corrosion mitigation measures.

This service supports informed decisions related to material selection, corrosion control, life prediction, and failure prevention in metallic systems exposed to corrosive environments.

Why Electrochemical Studies Are Required

Corrosion-related failures account for a significant portion of industrial asset degradation. Electrochemical studies help address challenges such as:

• Uncertainty in corrosion rates under actual service conditions

• Selection of suitable materials for corrosive environments

• Evaluation of corrosion inhibitors and protective measures

• Investigation of corrosion-related failures

• Prediction of long-term material performance

• Optimization of corrosion management strategies

Electrochemical testing provides a scientific basis for corrosion control decisions.

Scope of Electrochemical Studies

Electrochemical studies are applicable to:

• Carbon and alloy steels

• Stainless steels and non-ferrous alloys

• Coated and uncoated materials

• Weldments and heat-affected zones

• Process fluids and corrosive media

The scope is defined based on material type and service environment.

Study Methodology

Electrochemical studies follow a structured laboratory-based approach.

Selection of representative material samples and test environments.

Preparation of test specimens in accordance with standard procedures.

Electrochemical testing to evaluate corrosion potential, polarization behaviour, and corrosion kinetics.

Assessment of localized corrosion susceptibility such as pitting or crevice corrosion.

Evaluation of inhibitor performance and corrosion mitigation measures.

Interpretation of results to support material selection, design, and operational decisions.

Tools, Techniques and Standards

Electrochemical studies are supported by:

• Potentiodynamic and potentiostatic testing
