The carbides in high-chromium iron are very hard and wear resistant but are also brittle. In general, wear resistance is improved by increasing the amount of carbide (increasing the carbon content), white toughness is improved by increasing the proportion of metallic matrix (reducing the carbon content).

Grinding balls or crushing mills are elements used in cement industry. They require a high wear resistance under the action of abrasive products in the transformation of rock into fine particles smaller than a millimeter. To satisfy the mechanical and technological requirements, these balls are made of high chromium cast irons (10 to 13% chromium).

(1) Carbon: C has a significant effect on the matrix structure and carbide of high chromium cast iron. C is the main element for the formation of eutectic carbide (C R, F e)7 c 3, which plays a vital role in wear resistance. (2) CR: Cr is a basic alloy element which ensures excellent wear resistance and toughness of high chromium white cast iron.

In the dry machining of HCWCI materials, Tang et al. (2011) studied the machining of white chromium cast iron and found that the flank wear can be explained by the asperity contact model to describe the sliding and chipping wear. The volume of the removed debris by wear is proportional to the work done by friction force.

Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before …

High chromium white cast iron (HCWCI) is considered a hard machinable material because of its high carbide content, which when associated with a matrix, forms a rigid and very hard microstructure. This work evaluates the effect of the addition of 0.5% niobium (Nb) on the machinability of a HCWCI alloy with 25.6% chromium and 3.2% carbon.
