1. A surgical instrument comprising:
an end effector comprising:
a first jaw comprising a first channel formed therein, and
a second jaw pivotably coupled to the first jaw, the second jaw comprising
a second channel formed therein; and
a firing member longitudinally slidably engaged with the end effector to pivotably move the second jaw with respect to the first jaw and actuate the end effector, the firing member having an I-beam profile defined by an upper flange connected to a lower flange by a vertical blade member, the upper flange being slidable within the first channel and the lower flange being slidable within the second channel;
wherein at least a portion of each of the first jaw, the second jaw, and the firing member that are in sliding engagement comprises a sliding surface configured to resist galling, the sliding surfaces each comprising a metallic substrate layer, a metallic surface layer, a first surface coating layer overlying the metallic surface layer, and a second surface coating layer overlying the first surface coating layer.
