摘要

As the P/M industry strives to capture a portion of the high performance gear market designers must understand the capability limits of P/M steels, especially as compared to wrought steel alloys. Gears and sprockets are driven to failure through three failure modes: (1) single tooth bending fatigue, (2) surface pitting, also known as contact fatigue and (3) wear. While bending fatigue limits for P/M steels can be approximated using either axial fatigue or rotating bending fatigue test data, very little empirical data for contact fatigue exists for P/M steels. The Center for Powder Metallurgy Technology (CPMT) undertook a multi-year program to evaluate the RCF response of P/M steels using the Caterpillar style test rig at the Drivetrain Center of Penn State University. The results of this test program are described with an emphasis on the material-process parameters that directly influence the RCF results.
