Abstract: A seal assembly for rotary machines having a wear protection assembly with an abradable covering. The wear protection assembly has one or more wear protection features that enable in-operation opening of the seal assembly by increasing a clearance between a seal rotor and a seal slider of the seal assembly. In particular, the wear protection assembly is configured to open the seal assembly and increase the clearance of the seal rotor and the seal slider during slider air-bearing wear conditions, slider counterbore wear conditions, rotor air-bearing wear conditions, or extreme vibration wear conditions. Under such or similar wear conditions (or under conditions preceding or leading up to a wear condition), the wear protection assembly yields a pressure gradient and/or a fluid flow that oppose the forces acting to decrease the clearance between the seal rotor and the seal slider.
