Steels reinforced with ceramic phases such as WC, TiC, ZrO 2, and Al 2O 3 were tested for cavitation- and slurry-erosion resistance. These composite materials were produced using in-situ (reactive infiltration, the syntheses of primary carbides during the metallurgical process) and ex-situ (non-pressure infiltration) techniques. The microstructure and hardness of the composite materials were investigated. The ceramic phases increased the hardness by 200 to 350 HV1-10s. Erosion tests showed that the manufactured composite materials had higher wear resistance as compared to cast steel. In contrast, each of the composite materials showed lower resistance to cavitation-slurry erosion when compared to the cast steel.
