AbstractAs PM steel reach ever higher static and dynamic properties, their use in high performance applications is increasingly acknowledged by end-users. PM steels are now being pushed in applications where high wear resistance is required while maintaining good overall properties. Indeed, gears and cams can be subject to both rolling and sliding wear, leading to premature failure. This paper explores the effect of different alloys and process conditions on material loss in dry wear conditions. The impact of the rolling/sliding ratio is also studied. The PM component results are then compared those obtained for a wrought steel generally used in gear applications. The comparison shows that similar or even higher wear resistance can be reached by high density, high hardness PM steels.
