thermal barrier coatings
Thermal barrier coatings protect engine components from extreme heat, but they can be damaged by the dust that gets sucked in and turned into molten glass. Previous studies found yttria-stabilized zirconia coatings doped with alumina and titania demonstrated improved corrosion resistance against this molten glass. Now, researchers in Turkey explored whether these additives could improve the resistance of ceria-stabilized coatings as well.
Read MoreRepairing localized damage in thermal barrier coatings on aircraft turbine blades can require full coat removal and reapplication to avoid blocking cooling holes in the blade. Forschungszentrum Jülich researchers proposed a new laser-cladding-based additive manufacturing technique that shows promise repairing localized damage without the need for full coat removal.
Read MoreThermal and environmental barrier coatings are often used to protect turbine blades made from ceramic matrix composites—but these coatings are prone to damage caused by environmental silicate contamination. In three papers published in JACerS, researchers provide extensive insights into the many aspects of damage.
Read MoreThermal barrier coatings protect equipment against high temperatures in steel production. Researchers from Bartin University in Turkey found ferrochromium slag, a waste product from stainless steel production, could be used to create such coatings.
