Materials, heretofore unknown for use in bearing assemblies, which produce equal or better wear resistance at reduced materials cost have been identified. These alternatives fall into three general categories: (1) solid materials from which bushings and washers can be fabricated, (2) coatings bonded to metallic bushings and/or vanes to minimize total system wear, and (3) solid lubricant coatings placed on any bushing or vane stem to reduce friction.
