Abstract:
Advances in Gear Technology: A Symposium on Gear Manufacturing Through Powder Metallurgy
Shot peening is a very well recognized and documented process in the realm of wroght metals and alloys but the same cannot be said for Powder Metals (P/M). Yes shot
peening is being used very effectively to combat metal failures by a few companies who use it on millions of P/M parts but there is a great reluctance to talk about it so
that published data from test results or real life applications is almost non-existant. The intent of this paper is, then, to bring to light some of what little
documentation there is to show that the use of controlled shot peening can have a very positive effect on the fatigue life, for instance, of P/M parts. Also reviewed will
be the benefits of some recent innovations that enhance the use of shot peening. It is hoped that other P/M users and producers will see in shot peening a way to extend the
useful range of P/M parts and even save weight by considering the use of shot peening from the design stage.
