| description | The flow machine is furnished with an abradable ( 10 ) made of a particle composite material. This so-called composite ( 1 ) contains granular core particles ( 2 ) of a ceramic material. The surfaces ( 20 ) of the granular core particles carry functional layers ( 22 ) 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 ( 22 ') and material ( 21 ) of the granular core particles on the particle surfaces ( 20 ). Bonds ( 23 ) are formed between the granular core particles arranged in a porous composite by the intermediate phase. These bonds have a breaking characteristic for abradables. |
