Method of producing porous metal surface |
摘要 |
A porous surface is selectively formed on a workpiece such as a medical implant by pulsing a laser device in a controlled manner to produce a plurality of small, spaced-apart cavities of uniform or variable depth. The porous surface provides a mechanical grip with bone cement as well as a medium for bone and tissue ingrowth. |
