Abradable coating having variable densities

Abstract

A method of fabricating an abradable coating of varying density, and such an abradable coating of varying density. According to the invention, the method comprises the following steps: providing a substrate (32) having a first portion with its surface situated at a first level (A), and a second portion with its surface situated at a second level (B) different from the first level; depositing a precursor material on the first and second portions of the substrate (32); compressing the precursor material between the substrate and a bearing surface; and sintering the precursor material as compressed in this way in order to obtain an abradable coating (36) having a first portion (36a) on the first portion of the substrate, and possessing a first density, and a second portion (36b) on the second portion of the substrate, and possessing a second density distinct from the first.
