A process of electrically embedding carbon onto a steel surface in order to increase its roughness. Sometimes used on the cavities of clamp dies and clamp inserts to improve their grip on the tube without leaving the marks serrations or knurling do. The drawback is that this surface treatment degrades faster than serrations and is expensive to apply. “Surfalloy” and “Rocklinizing” are trade names for this process.
