New methods for manufacturing alloy composites have been used to produce a number of wear parts for the mining industry. The use of composites incorporating white cast iron and steel permit brittle and wear resistant materials tobe used in applications where moderate impact conditions are encountered. Analysis of the alloy composite interfaces has provided an enhanced undertsnading of the bonding mechanisms between the white cast iron and the steel and has also permitted further improvements in the manufacturing techniques. Analysis methods used to examine the interfacial features include quantative x-ray mapping (QXRM) and electron beam backscattered diffraction (EMSD) mapping. Examples of successful field trials include mineral sands and wear parts for heavy earthmoving equipment.
