Tribological properties of Babbitt alloy coatings modified with carbon nanotubes

The tribological properties of composite coatings produced via the plasma-powder surfacing on a steel substrate are investigated. SnSb 8 Cu 4 Babbitt alloy powder and composite pellets on its basis containing carbon nanotubes are used as fillers. The changes in the coefficient of friction, dispersio...

Description
Summary:The tribological properties of composite coatings produced via the plasma-powder surfacing on a steel substrate are investigated. SnSb 8 Cu 4 Babbitt alloy powder and composite pellets on its basis containing carbon nanotubes are used as fillers. The changes in the coefficient of friction, dispersion parameter, and wear rate are studied for deposited Babbitt coatings modified with carbon nanotubes produced by the catalytic pyrolysis of a propane–butane mixture on a NiO/MgO catalyst and via the synthesis of carbon nanostructures on the copper powder surface. The coefficient of friction and wear rate are compared for coatings modified and not modified with carbon nanotubes.
