Babbitt coatings (White metal) on a tin basis are often applied for producing high-grade Babbitt coatings in bearing cups, guide tracks and other slide bearing applications.
Compared with conventional pouring of Babbitt, spraying those layers has a number of advantages:
- The piece does not have to be galvanised, an optimum bond can be obtained on cast iron, steel and bronze.
- Dovetail joints or special sectioning to obtain the right bond are not required.
- The layer thickness can generally be limited to a minimum.
- If thick layers are required, a buffer coating of aluminium bronze can be applied, which also serves as an emergency bearing surface.
- Sprayed Babbitt layers have an extremely even structure, there is no chance of inclusions or shrinkage cavities, which produces a consistent high wear and pressure resistance.
- Low friction coefficient
- High wear and pressure resistance
- Aluminium bronze coating as buffer coating for emergency bearing surface is possible
- Bearing cups (slide bearings)
- Guide tracks
