Apparatus and method for friction testing. |
| 摘要 |
<p>Apparatus for testing friction has a pressing punch (10) a press (5) for pressing the punch (10) against a test piece held by a holder (18) and a drive (14,15) for causing relative rotation of the punch (10) and the holder (18) about an axis perpendicular to the tested surface. For testing surfaces of metal pieces, especially coated surfaces, the punch (10) carries at least one projecting test tool (22) and the relative rotation is for less than one complete revolution. <IMAGE></p> |
