Abstract

A sealing material for high temperature, liable to frictional wear comprises a sintered mass of fibres and/or of fine metal powders. These fibres or powders consist essentially of I, Al, Cr, II or I, Al, Cr, III, I, II or III having the meaning given in Claim 1. The exposed surfaces of the fibres and powders are protected against oxidation at elevated temperature by an Al2O3 coating formed on the substrate, this substrate having an Al content of at least 4 %. The material can be used between the rotating and adjacent stationary components of turbine machines such as compressors and turbines operating at elevated temperatures.
