|---|---|
| Chemical designation | CuSn12Ni2 build-up welded on 42CrMo4 |
| State | L-PBF (Laser Powder Bed Fusion) |
| Etching | Klemm III |
By means of a L-PBF, the bronze CuSn12Ni2 was welded as a powder onto the quenched and tempered steel. The sliding bearing layer still contains some micropores that can act as lubricant deposits.
The microstructure was developed by colour etching according to Klemm III and shows a very fine-grained, 2-phase microstructure.
