| Abstract | The tribological behaviors of tungsten carbide (WC) based cermet/Ti3SiC2 tribo-pair at elevatedtemperatures were investigated. Lead oxide (PbO) was added as a solid lubricant. The tribo-physical andtribo-chemical changes on sliding surfaces were studied in detail. The results indicated that adhesiveand abrasive wear due to removal of metallic binder and pullout of grains were the dominant wearmechanisms at room temperature. At high temperature, tribo-physical changes (i.e. mechanical mixtureor sintering) and tribo-chemical reactions including complex reaction and oxidations were induced byfrictional heat combined with high environmental temperature. As a result PbWO4 was formed as areaction product and acted as a solid lubricant. PbWO4 and tribo-oxides along with the physicallychanged layer on the sliding surfaces were favorable to reduce wear of both materials. At hightemperature, the wear mechanism varied from adhesive and abrasive wear at room temperature tolubrication by tribo-layer containing PbWO4, tribo-oxides, and sinters at high temperatures. |
