In order to improve the wear resistance of ductile iron, different contents TiC particles are added into iron used lost-foam casting and tribological behavior is studied through a ball-on-disk sliding test. It found that with increase content, pearlite content gradually increases, which attributed promoting heterogeneous nucleation cementite increasing cooling rate melt. The second-phase streng...

FeCrNi medium entropy alloy (MEA) is a promising structural material due to its outstanding mechanical properties and corrosion resistance. However, study on the high-temperature tribological behaviors of MEA still scarce. This work investigates performances against Si3N4 balls over typical operating temperatures from 25 800 °C. The exhibits excellent wear resistance at an intermediate temperat...
