CORD FOR PROJECTION COATING AT THE TORCH AND ITS USE FOR DEPOSITING A QUASI CRYSTALLINE PHASE OVER A SUBSTRATE.

摘要

The invention relates to a bead for spraying with a torch and its use for depositing a quasi-crystalline phase on a substrate. BR/ This cord (1) comprises a core comprising an organic binder and a powder or a mixture of powders capable of forming an almost crystalline alloy, this core being surrounded by a sheath of organic material. BR/ It thus makes it possible to deposit a quasi-crystalline alloy on a substrate by developing this alloy in the flame (3) of a projection device, from commercial powders of the constituents of the quasi-crystalline alloy.
