Coatings

Corrosion-resistant coatings can significantly increase the lifetime of materials while reducing maintenance and replacement costs. SRI uses a variety of coatings and coating techniques to address client needs in specific applications such as corrosion protection of incinerators, heat exchangers, chemical heat pumps, and rebars in concrete. We focus on developing new coatings and coating techniques that allow deposition at lower temperatures and lower cost. Most of our recent developments have been in corrosion protection of metals in highly aggressive environments.

A process for making diffusion coatings at lower temperatures and shorter timeframes than typical pack cementation is being used in numerous applications. Our research has helped reduce the thermal budget for the coating process, making it competitive with other coating technologies. We have also obtained deep diffusion depths of protective elements in low-cost substrate materials that provide excellent corrosion and erosion resistance for the substrate material in highly aggressive environments.

SRI's research in coatings is funded by NCHRP, GRI, and commercial clients. Potential application areas for the research include:

• Chemical heat pumps
• Petrochemical industry
• Incinerators
• Boilers
• Steam turbines
• Residential and commercial heaters
• Condensing heat exchangers
• Waste treatment plants
