Corrosion coupon analysis is a fundamental technique in the field of corrosion science and engineering. It involves the use of specially designed metal coupons that are exposed to a corrosive environment for a predetermined period. These coupons serve as sacrificial specimens, allowing researchers and engineers to assess the rate and extent of corrosion within a system. By carefully measuring the weight loss, corrosion products, or changes in the coupon's physical properties, analysts can gain valuable insights into the corrosive processes at play, helping to inform corrosion control and mitigation strategies. Corrosion coupon analysis plays a crucial role in industries such as oil and gas, manufacturing, and infrastructure, where protecting assets from corrosion-related damage is essential for safety, longevity, and cost-effectiveness.
