What is corrosion?
Corrosion is degradation of metals through chemical or electrochemical reaction between metals and its environment. Typical example is oxidation of iron and steels, resulting in rust or corrosion products.
Corrosion occurs in all industries from automotive and aerospace to infrastructure, construction, marine, petroleum, oil & gas, power, paper making, food processing, bioengineering, and pharmaceuticals. Corrosion is costly, dangerous, wasteful, and unsightly in some cases.
What is corrosion engineering?
The core of corrosion engineering is corrosion control and prevention, which includes conducting failure analysis and investigation on corroded parts to understand corrosion mechanisms and corrosion causes, and studying corrosion preventive methods to minimize or control corrosion.
Corrosion failure analysis
Corrosion failure analysis (or corrosion failure investigation)is to adopts systematic analysis approach to determine root cause(s) and mechansim(s) of corrosion failure and provide counter measures to prevent similar corrosion failure recurrence.
Corrosion expert witness
Corrosion expert witness is a person with specialised and extensive knowledge in corrosion based on training, study or experience. Engaging corrosion expert witness services can be from the legal, insurance and industrial sectors as well as government agencies for assistance in settling lawsuits, litigations, arbitrations, safety related prosecution, construction disputes and insurance claims related to corrosion issues.
Corrosion expert witness may be required in litigation proceedings including Courts and tribunals to assist them in reaching a decision and justifications when the Courts require expert evidence. Corrosion expert witness provides expert opinions and evidences in their testimony mostly based on forensic investigation or analysis on the subject corrosion issues as well as scientific knowledge.
More details about expert witness, please refer to Expert Witness Services.
As corrosion is chemical or electrochemical reaction between metals and environment, electrochemical cell(s) are formed in corrosion process. Four elements must be present for corrosion to occur.
- Anode: The site of metal where oxidation (corrosion) occurs
- Cathode: The site of metal where corrosion does not form
- Metallic pathway: Provides the flow of electrons from anode to cathode
- Electrolyte: A liquid that contains charged particles and allows ions to flow from cathode to anode
The interaction between these four elements is known as the corrosion cell. Three elements of corrosion are already present in most metals: anode, cathode and metallic pathway. Only missing element is the electrolyte that comes from the atmosphere or chemicals.
