| 81 | Method for Imparting Residual Compressive Stress in Metal Parts | US11556679 | 2006-11-03 | US20070140887A1 | 2007-06-21 | Gerard Perkins |
| A method of hardening metal parts, such as a rotor or drive link, and parts thus produced. Preferably the method includes imparting residual compressive stresses into the metal parts and uses various small ball type structures to create small compressions in the surfaces of the metal parts. The compressions apply residual stresses to the parts, which strengthen the metal. The substantial uniform ball type structures are pressed into the metal part to control the application of stress into the part and maintain substantial uniform properties within the metal part, which resists future stresses as the part is used in its desired machinery and/or processes. | ||||||
