FIELD: chemistry.
SUBSTANCE: invention relates to slurries for aluminising superalloy components and may be used for the manufacture of components exposed to hot corrosive gases, like, for example, gas turbine components. The slurry comprises an organic binder and a solid content including aluminium, yttrium and hafnium; it also comprises a sulphur content which is not more than 5 ppm by weight of the composition. A superalloy component (1) comprising an aluminide coating, where the coating comprises at least one layer (3), comprising hafnium and yttrium in addition to aluminium.
EFFECT: improved oxidation and corrosion resistance of the superalloy components with the aluminide coating.
