Abstract:
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 to be
used in applications where moderate impact conditions are encountered. Analysis of the alloy composite interfaces has
provided an enhanced understanding 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 quantitative x-ray mapping (QXRM) and electron beam backscattered diffraction (EBSD) mapping.
Examples of successful field trials include mineral sands dredging and wear parts for heavy earthmoving equipment.
