Silicon nitride (Si 3 N 4 ) materials with preferentially aligned β‐Si 3 N 4 grains were tribologically characterized with respect to their possible application in a high‐pressure gasoline pump. Tribological tests were performed under oscillating sliding conditions lubricated with isooctane as a substitute for gasoline using Si 3 N 4 counterbodies. Performance in terms of wear of the aligned materials surpassed that of nonaligned reference Si 3 N 4 , as well as that of self‐mated silicon carbide, zirconia, alumina, and a steel sliding pair. The plane perpendicular to the extruding direction and parallel to the hot‐pressing axis was the most wear resistant.
