Purpose: The Coatings and Corrosion Laboratory improves coating and corrosion test methods while gauging the durability and performance of innovative coating systems designed to prevent corrosion of steel bridges.
The mission of the Coatings and Corrosion Laboratory is to: evaluate the durability and corrosion performance of structural materials; research and develop methods of preventing or delaying corrosion; analyze the effectiveness of innovative coatings systems in preventing corrosion; perform metallic material property determinations; and provide forensic, failure analysis and lot testing for metallic structural components.
Description: The Coatings and Corrosion Laboratory can perform both long- and short-term corrosion rate research and tests on structural and reinforcing metals. Protective coating systems are evaluated with accelerated laboratory techniques and outdoor natural exposure conditions. Innovative testing procedures are developed for assessing corrosion and premature coating failures on steel bridges. Other highway construction materials such as grout, concrete, and soil are analyzed and evaluated for long-term durability regarding corrosion of reinforcement. In addition, the lab assists State Departments of Transportation (DOTs) to solve a variety of infrastructure-related corrosion and coating problems and provides technical assistance and input where needed.
Special Capabilities: The Coatings and Corrosion Laboratory performs the following activities.
Services: The Coatings and Corrosion Laboratory performs the following services.
|Ion Chromatography - To determine the concentration of ions in samples with high accuracy. Performs multiple anion analysis with automated sampler.|
|Automated Titration System - To determine chloride content in a variety of samples, including concrete, grout, soil, and cement.|
|Drop Shape Analysis - To measure contact angle using optical method and determine surface free energy of non-porous and porous solids based on contact angle measurements. Determines polar and disperse fractions of the surface free energy.|
