METHOD FOR PRODUCING A LIGHT-ALLOY BEARING BUSH WITH A ROUGH EXTERNAL SURFACE |
| 摘要 |
The aim of the invention is to produce a light-alloy bearing bush with a rough external surface. To achieve this, particles, which are subsequently surrounded in part by the molten metal, are applied to the surface of the casting mould. When the bearing bush is released from the mould, the particles remain in said bush and are subsequently removed from the bearing bush preform either mechanically or by being dissolved in liquid. |
