| description | A seal system, for an apparatus that includes a rotatable portion with airfoils coupled thereto and a stationary portion with an inner surface, includes an abradable portion including at least one abradable layer of an abradable material formed over the inner surface. The seal system also includes an abrading portion disposed over at least a portion of a substrate of the airfoil. The abrading portion includes at least one abrading layer formed on at least a portion of the substrate and a plurality of abrasive particles embedded within the abrading layer. The plurality of abrasive particles includes at least one of substantially all of one of tantalum carbide (TaC), aluminum oxide (Al2O3), and ziconia (ZrO2), cubic boron nitride (cBN) and Al2O3 in predetermined ratios, cBN, Al2O3 and ZrO2 in predetermined ratios, Al2O3 and ZrO2 fused together in predetermined ratios, and TaC and Al2O3 in predetermined ratios. |
