High-chromium white cast iron is virtually a composite material with a metallic matrix reinforced with carbide particles. As shown by Kosasu et al. (Ref 7), matrix phase composition can be suitably modified to achieve a proper balance between resistance to abrasion and the toughness needed to withstand repeated impact.. Table 1 shows the High-chromium white cast irons are commonly used in applications requiring excellent abrasion resistance, as in the mining and mineral ore processing industry. Their excellent abrasion resistance is mainly due to their solidification microstructures. During their solidification, high levels of chromium (16–32%) lead to the formation of a Effect of molybdenum and chromium contents in sliding wear of high

A high-chromium-containing wastewater sample was collected from the tank used in the current treatment carried out in the electroplating industry. Nowadays, this small industry produces bolts, clamps, metal clips, and other materials used in agricultural machines and generates around 300 L/week of chromium effluent. After proper Whit cast irons, and specifically high chromium white cast irons, have been developed and deployed worldwide for making mechanical components of crushing and grinding machines due to the combination of high wear resistance and good mechanical strength.

High chromium cast iron (HCCI) has been widely used as wear-resistant material in the industry. Alloying is an effective way to improve the microstructure and mechanical properties of HCCI. This paper added multi-component V-Fe-Ti-Nb-C-Zr-B alloy (VFC) to HCCI, showing a significant synergistic solution-strengthening effect. The High wear resistance of chromium Fe-Cr-C alloys is provided by the presence in their structure of a large amount of a carbide phase with high hardness (M 7 C 3,M 3 C and M 23 C 6 ) [9][10][11].Microstructural and wear investigation of high chromium
