Cr(VI)-FREE COATINGS

By Gerald Ondrey |

Praxair Surface Technologies, a division of Praxair, Inc. (Danbury, Conn.; www.praxair.com), has recently introduced a new line of ceramic aluminum coatings that are said to have the same performance as legacy chromium (VI)-containing coatings. The company’s SermeTel CF and SermaLoy J CF systems are suitable for applications in the aerospace and power-generation industries, where they can be used to extend the useful lifetime of critical components, such as gas turbines and other industrial equipment, by providing protection from corrosion, heat degradation and fouling.
