Preparation of TiC Reinforced Iron Based Composite Powder by Electrochemical Reduction from High Titanium Slag with Carbon

Titanium carbide（TiC） reinforced iron（Fe） based composite powder with a multi-core structure was electrochemically prepared directly from high titanium slag and carbon powder.The electrochemical reaction pathways for the sintered piece of the slag and carbon were investigated by examination of the partially and fully reduced samples using XRD and SEM-EDS analyses.The reduction process of the sintered piece of high titanium slag and carbon can be divided into two main stages.The first stage is the electrochemical reduction of the high titanium slag,leading to the formation of Fe,titanium monoxide（TiO） and calcium titanate（CaTiO₃）.The second stage is a transformation process of TiO→TiC_xO_1-x→TiC.The ratio of high titanium slag to carbon powder affects the final composition of the products,and the increase in carbon powder addition can increase the TiC content of the final products.
