METHOD FOR THE CONTROLLED MECHANICAL WORKING OF SINTERED POROUS POWDER METAL SHAPES TO EFFECT SURFACE AND SUBSURFACE DENSIFICATION |
| 摘要 |
<p>A method is provided for partially densifying a selected surface portion of a sintered porous powder metal element while applying restraining pressure to other selected portions of said element in order to inhibit growth and cracking of said element during the partial cold deformation thereof. The method is particularly applicable to the production of annular bearing rings.</p> |
