Abstract
In this study, the tribological behavior of Ti3AlC2 in both deionized water and artificial seawater was investigated. The tribological mechanisms of different tribopairs in the two aqueous environments were discussed in detail. When sliding against AISI 316L stainless steel, Al2O3 and Si3N4 in the two environments, Ti3AlC2 displayed poor tribological properties, and the mainly wear mechanisms were mechanical wear by counterparts. The tribo-chemical products mainly consisted of TiO2 and Al2O3 in both the liquids. However, the Ti3AlC2/SiC tribopair could provide excellent lubrication in both deionized water and artificial seawater. A smooth tribofilm was formed on the Ti3AlC2 worn surface, where the tribofilm was the mixture of TiO2, Al2O3 and SiOx. The tribofilm was believed to be responsible for the excellent lubricating effect. In light of these results, the Ti3AlC2/SiC tribopair held promise to serve in marine tribological applications.
