Babbitt surfacing is used in tribological applications because of its low friction coefficient. Thermal spray surfacing and pouring are two widely used production processes for Babbitted parts. This paper presents a comparative analysis of structures and friction properties of Sn-Sb-Cu Babbitt layers produced by these techniques. The sprayed Babbitt coatings were produced by arc spraying of 1.6 and 3 mm diameter wire.

Babbitt is used at tribology applications according to its low friction coefficient. Thermal spraying and pouring are widely used production processes of Babbitted parts. Comparative analysis of structure and wear properties of Babbitt layers produced by these technologies was done. Examples of typical arc sprayed Babbitted part's applications which were done at Mashprom are represented.
