Praxair has introduced of a new line of chromium (VI)-free ceramic aluminium coatings for the aerospace and power generation industries. Praxair Surface Technologies’ new line of slurries sustainably produces coatings with the same high performance of legacy chrome-containing coatings.
The company’s SermeTel™ CF and SermaLoy® J CF systems meet the stringent requirements of gas turbine OEM specifications and preserve the surface finish of engine components to extend the useful life of critical parts in gas turbines and industrial equipment. The coatings are also REACH-compliant (Europe’s regulation for the Registration, Evaluation, Authorisation and Restriction of Chemicals).
SermeTel™ CF Coatings are chrome-free replacements of legacy SermeTel™ 5380, SermeTel™ 2F-1 and SermeTel™ 6F-1 coatings. They provide protection from corrosion, heat degradation and fouling of components.
The SermaLoy® J CF Coating is a chrome-free diffusion slurry that offers equivalent performance to traditional Sermaloy® J coatings. SermaLoy® J CF coatings provide protection against hot corrosion and oxidation in gas turbine engines and other severe environments.
