Estimating the term…
A method for producing an abradable ceramic composite coating on a substrate, the method including: obtaining a pulverulent composition including a matrix powder and a ceramic filler hydrated precursor powder having a lamellar crystallographic structure, wherein the ceramic filler powder represents from 5 to 40% of the combined volume of the matrix powder and the ceramic filler powder, compressing the prepared pulverulent composition at a pressure greater than 150 MPa, and a step of reactive sintering the obtained pulverulent composition, during which the compression is maintained, at a temperature of less than 550° C., and the particles of the matrix powder in the sintered pulverulent composition have an aspect ratio of 2 or greater.
