Abstract

Abstract : Silicon nitride (Si3 N4 ) materials with preferentially aligned β‐Si3 N4 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 Si3 N4 counterbodies. Performance in terms of wear of the aligned materials surpassed that of nonaligned reference Si3 N4, 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.
