“…2,3,6,8 The size of the ceramic particle has a key impact on the electrodeposition process. 10,11 For instance, nanocomposites often exhibit superior mechanical and tribological properties compared to microcomposites. 2,9 However, nanoparticles tend to agglomerate in the electrolyte leading to lower ceramic particle fractions in the deposit.…”

The effect of a cationic dispersant, polyethyleneimine (PEI) on electrodeposition of nickel/titanium carbide (Ni/TiC) nanocomposites is characterized. Enhancing the dispersion of TiC nanoparticles in the electrolyte and increasing TiC amount and uniformity in the deposit are crucial to get superior mechanical and tribological nanocomposite properties. Therefore, a key challenge in reaching enhanced composites is the optimization of the dispersant concentration that improves the nanoparticle dispersion in the electrolyte and achieves high and uniform TiC incorporation into the deposit without suppressing electrodeposition. It is determined that PEI at a concentration of 125 ppm increases the stability of TiC nanoparticles in the electrolyte and TiC vol% in the deposit significantly without any substantial inhibition on the electrodeposition kinetics. Ni/TiC electrodeposition is also characterized as a function of key parameters such as TiC electrolyte concentration, current density, and rotation speed in the presence of PEI. Higher and more uniform TiC nanoparticle incorporation is attained for the electrolyte containing PEI than the electrolyte with no dispersant for all cases. Uniform nanocomposites with improved hardness is obtained as a result of Ni/TiC electrodeposition in the presence of the cationic dispersant.

A number of processes are used for the preparation of composite materials depending on the required properties and choice of material system. Some of these are mentioned here such as Al-SiC, Al-Al 2 O 3 , Mg-SiC, Mg-Al 2 O 3 of high specific strength , stiffness, temperature resistance, low thermal expansion coefficient, wear resistance and thermal conductivity are prepared by fusion infiltration, extrusion, forging, gravity and die casting while PbC and Pb-Al 2 O 3 for high stiffness and creep resistance are prepared by fusion infiltration only [13]. Cu-W for burn up resistance and Pb-C and Brass-Teflon for load carrying capacity and wear resistance are prepared by powder metallurgy and infiltration. Similarly Equal Channel Angular Pressing (ECAP) for Al-Al 2 O 3 , High Pressure Torsion (HPT) for Cu-Fe composite, Hot pressing for Cu-Al 2 O 3 composite, hot extrusion for Mg-Al 2 O 3 , Sintering for Cu-MgO, Microwave sintering for Co-WC, Plasma spraying for Al-CNT, High velocity oxyfuel spraying (HVOS) for Ni-Al 2 O 3 , Cold spraying for Co-WC. Some other techniques such as spark plasma sintering, sol-gel and electrodeposition are also available for the preparation of metal matrix nanocomposites.

“…Therefore, TiC composites are used in various applications, such as multiple types of engine shaft parts [1][2][3]. TiC composites can be synthesized by different methods, including mechanical alloying [4], electrochemical production [5], thermal plasma technique [6], active-sintering [7] and carbonization [8][9]. However, these methods require complicated procedures and high amounts of thermal energy during the synthesis process.…”

Titanium carbide (TiC) composite powder was synthesized via the self-propagating high-temperature synthesis (SHS) method using leucoxene as a source of titanium oxide (TiO2) and magnesium (Mg) as an initiator. The effect of Mg content on synthesized TiC composite powder was characterized in terms of chemical composition and morphology by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Results showed that adding 1.5 moles Mg into the reactant system leached with 0.1 M hydrochloric acid solution was the optimal condition, and TiC was apparent in the XRD analysis at a particle size of less than 150 μm.
