A self-lubricated oxide-containing tribo-layer was induced to form by continuously adding particles of MoS{sub 2}, Fe{sub 2}O{sub 3} or their mixtures onto sliding interfaces of AISI H13 and 52100 steels. The artificial tribo-layer was always noticed to form continuously and cover the worn surface (termed as cover-type), whereas the original tribo-layer spontaneously formed with no additive was usually discontinuous and inserted into the substrate (termed as insert-type). Clearly, the cover-type and insert-type tribo-layers exactly corresponded to low and high wear rates, respectively. For the mixed additives of Fe{sub 2}O{sub 3} + MoS{sub 2}, the protective tribo-layers presented a load-carrying capability and lubricative function, which are attributed to the existence of Fe{sub 2}O{sub 3} and MoS{sub 2}. Hence, the wear rates and friction coefficients of H13 steel were markedly reduced.
