Abstract
High performance P/M prototype gears made by high velocity compaction (HVC) and sinter-hardening has been experimentally investigated with respect to mechanical properties. Experiments were conducted on high density sinter-hardened planetary gears made of Astaloy CrM and D. DH-1. The high velocity compacted prototype gears, compacted to a density of 7.5 g/cm3, were compared to reference gears representative for conventional processing routes that leads to densities up to 7.1 g/cm3.
As a result of increased density, the high velocity compacted and sinter-hardened planetary gears showed significantly improved hardness and static tooth strength compared with conventionally compacted and hardened planetary gears.
