In fact, Scandian et al. 11 analyzed the relationship between the microstructure and the wear behavior of high chromium white cast iron using a pin-on-disc tribometer at room temperature under V = 0.31 m/s and F = 20 N. The analysis of the results reveals that the microstructure has a strong effect on the wear resistance of the …
White Cast Iron: Microstructure: White cast iron has a microstructure consisting of cementite (iron carbide) and pearlite. The absence of graphite makes it appear white when fractured. Carbon Content: White cast iron has a higher carbon content, typically above 2%, resulting in the absence of free graphite. Properties:
