Comparative Characteristics of Coatings Produced from Sn-Sb-Cu Babbitt by Arc Spraying, Gas Surfacing and Pouring


 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.
