Abstract
A machine abradable layer (10), comprises a particle composite material, and a composite (1) that contains ceramic particles (2) with functional layers on the surface (20). The layers form stable intermediary phases at high operating temperatures. The intermediary phases are partly formed by a chemical reaction between a precursor and the ceramic particles.
The material is used as an abradable layer for a machine, eg a gas turbine, turbo compressor etc.
The layer can operate at high temperatures.
