Wear Behavior and Self Tribofilm Formation of Infiltration-Type TiC/FeCrWMoV Metal Ceramics Under Dry Sliding Conditions

A new type high temperature self-lubrication TiC/FeCrWMoV metal ceramic was fabricated successfully by applying an innovating technology which molten solid lubricant (60Pb40Sn-15Ag-0.5RE) was infiltrated into metal ceramic preforms with an interpenetrating network using a vacuum high pressure infilt...
