High-temperature oxidation and corrosion play an important role in the selection of materials for geological and aerospace applications. Southwest Research Institute (SwRI) provides technical assistance for:
- Molten salt corrosion
- Protective coatings
Corrosion Process Facilities and Equipment
State-of-the-art laboratory facilities and extensive computer modeling capabilities, as well as plant-site investigations and monitoring, are used to meet client needs.
High-temperature oxidation and corrosion kinetics can be monitored using a state-of-the-art continuous-recording microbalance. Our thermogravimetric analysis (TGA) system has a heating furnace with 1,700°C temperature capability, and is supported by an associated data acquisition and analysis system. Staff have extensive experience in evaluating high-temperature oxidation and corrosion mechanisms, as well as in the development of protective coatings to mitigate materials degradation.
