摘要： Disclosed are a method for manufacturing an abradable coating having variable densities and an abradable coating of said type having variable densities. According to the invention, the method involves the following steps: providing a substrate (32) that has a first portion, the surface of which is at a first level (A), and a second portion, the surface of which is at a second level (B) that is different from the first level; applying a precursor material to the first and second portions of the substrate (32); compressing the precursor material between the substrate and a support surface; and sintering the compressed precursor material so as to obtain an abradable coating (36) comprising a first area (36a) which faces the first portion of the substrate and has a first density, and a second area (36b) which faces the second portion of the substrate and has a second density that differs from the first density.
