Abstract
The flow machine is furnished with an abradable () made of a particle composite material. This so-called composite () contains granular core particles () of a ceramic material. The surfaces () of the granular core particles carry functional layers () which form an intermediate phase of the composite which is stable at a high operating temperature. The intermediate phase in this process has been produced in situ at least in part by a chemical reaction of a precursor material (') and material () of the granular core particles on the particle surfaces (). Bonds () are formed between the granular core particles arranged in a porous composite by the intermediate phase. These bonds have a breaking characteristic for abradables.
