RIBBON FOR COATING BY TORCH SPRAYING AND ITS USE FOR DEPOSITING A QUASI-CRYSTALLINE PHASE ON A SUBSTRATE

摘要

The invention relates to a ribbon or bead for coating by torch spraying and its use for depositing a quasi- crystalline phase on a substrate. The bead or ribbon (1) comprises a core having an organic binder and a powder or a mixture of powders able to form a quasi-crystalline alloy, said core being surrounded by an organic material sheath. It makes it possible to deposit a quasi-crystalline alloy on a substrate whilst preparing said alloy in the flame (3) of a spraying apparatus and using commercial powders of the constituents of the quasi-crystalline alloy.
