The tribological properties of Cl-containing antiwear (AW) and extreme
pressure (EP) additives in the sliding of steel against aluminum allo
y were investigated by an Optimol SRV tester. It was found that Cl-con
taining additives were effective at reducing the wear of aluminum. The
acting mechanism of Cl-containing additives in the lubricated aluminu
m-on-steel system was proposed. (C) 1997 Elsevier Science S.A.
