PNNL

Abstract

Corrosion is a problem is estimated to cost US industries $300 billion per year. Researchers at Pacific Northwest National Laboratory have developed a new ceramic-based composite? coating for steel and superalloys that prevents corrosion, oxidation, carburization and sulfidation that commonly occur in gas, liquid, steam and other hostile environments. Although corrosion resistant coatings are currently in use, better coating materials and methods are essential to achieve enhanced performance and improved energy efficiency. The PNNL-developed aluminide coating has significant advantages over those currently available: lower temperature processing, compatibility with both ceramics and metals, higher upper use temperatures and the ability to have properties tailored to match a wide number of useful substrates.
