Abstract
In this paper, the tribological properties and the film-forming properties of the friction-promoting grease (FPG) A under point-contact conditions were investigated by conducting respectively four-ball experiments and FPG A-lubricated ball-and-disc contact experiments. The experimental results indicate that the coefficient of friction (COF) decreases with an increase in the rotating speed at a constant load; FPG A has a good film-forming ability and a good adhesion property; the application of FPG A under hoist’s normal operation conditions could greatly protect the contact surfaces from wear and supply a sufficient COF.
