发明名称 A component having an abrasive layer and a method of applying an abrasive layer on a component
摘要 <p>The tips (44) of gas turbine engine turbine rotor blades (26) are provided with an abrasive layer (60) and the abrasive layer (60) comprises chromised (64) silicon carbide grit (62) protruding from a layer of material (66). In particular the abrasive layer (60) comprises a mixture of cubic boron nitride grit (68) and chromised (64) silicon carbide grit (62) and the cubic boron nitride grit (68) and the chromised (64) silicon carbide grit (62) protruding from the layer of material (66). The cubic boron nitride grit (68) has a greater dimension than the chromised (64) silicon carbide grit (62). The cubic boron nitride grit (68) cuts the majority of a track in an abradable structure (59) and then the chromised (64) silicon carbide grit (62) provides any additional cutting of the abradable structure (59). </p>
