摘要：

The wear characteristics and the mechanism of sliding wear of boronized steel under unlubricated conditions were studied. Characteristic wear curves of FeB and Fe2B boride layers formed on SAE 1045 steel were similar in form. The maximum wear rates were obtained under a sliding velocity of 0.30 m s-1 for FeB specimens and 0.50 m s-1 for Fe2B specimens. Under such conditions both mechanical wear caused by scratching and oxidative wear occurred. Under conditions of mild wear the wear loss was caused mainly by oxidative wear. Under conditions of heavy wear destruction of the sliding surface was caused by thermal stress. The wear debris was composed principally of iron oxides (α Fe2O3, Fe3O4) formed by oxidative wear, α iron and borides (FeB, Fe2B) produced by mechanical wear and B2O3 produced by the preferential oxidation of boron in the boride layer. © 1979.
