dc.description.abstractAdvances in Laser Metal Deposition (LMD) provide technical opportunities such as the geometric restoration of worn components and custom surface coatings to enhance wear and corrosion resistance. Commercial applications include high Cr white cast iron (HCWCI) alloys for mining applications. In this study, a Fe-2.2C-30Cr-10Ni-6Mo alloy was deposited on mild steel substrates to characterise the effect of the LMD process, and a subsequent 1030 °C/4 h s heat treatment, on the microstructure, corrosion behaviour, and abrasive wear behaviour. The LMD microstructure consisted of fine eutectic Cr enriched M7C3 and Mo enriched M2C carbides in a γ-Fe matrix. This led to good abrasive wear and corrosion properties. The post heat treatment had an adverse effect on both the abrasion and corrosion resistance of this alloy, primarily due to the transformation of M7C3 to softer M23C6 carbides, and Cr depletion in the matrix. © 2019 Elsevier B.V.en_AU
