The ability of the antifriction materials to withstand with no lubrication for a while\ncan be a solution for the catastrophic failure of automotive journal bearings from the internal\ncombustion engines in accidental breakdown of the oil pump. A thick layer of antifriction\nmaterial (babbit) was deposited by gravitational casting on a steel disk substrate. Four\ntribological disk samples coated with babbit are tested against a steel shoe on Amsler\ntribometer at different speeds and loads in dry friction. The values of the friction coefficient\nversus speed and load are presented, the obtained results indicating a mild wear regime,\nrecommending the new babbit as a possible coating for the bushes of the journal bearings in\nautomotive internal combustion engines. Further tests must be dedicated to the establishment\nof the wear intensity of the steel shoe - babbit disk tribological pair, both for motor oil\nlubricated and dry friction conditions.
