Correlation between the abrasive ability of ceramic reinforced amorphous metal matrix composites and the adhesion energy between the amorphous matrix and the ceramic particles

Wear and friction behavior of nanosized TiB2 and TiO2 particle-reinforced casting A356 aluminum nanocomposites: A comparative study focusing on particle capture in matrix

“…Various interactions, such as van der Waals force, interfacial force, the integrated disjoining pressure, and the intermolecular interaction have been considered as the repulsive force, while the viscous drag force that acts on the moving particles to resist the pushing by the solidification front is considered as the attractive force. 25,26 The aim of the present study is to investigate the effects of ceramic nanoparticle type and content on particle capture in aluminum matrix and consequently on wear properties of aluminum matrix nanocomposites (AMNCs). Different volume fractions of TiB 2 and TiO 2 nanopowders were incorporated into molten A356 aluminum alloy via stir casting method.…”

Performance of a cutting tool made of steel matrix surface nano-composite produced by in situ laser melt injection technology

“…While TiC has superiority in both hardness (Kalpakjian, 1995) and thermodynamic stability (Barin, 1993) over WC, both of these particles are metallic in nature, and thus are well wettable by the steel matrix ensuring strong adhesion between the matrix and the reinforcing particles. This is essential to prevent reinforcing particles to turn out of the matrix without being worn, what is known to be one of the wear mechanisms of MMCs (Kaptay et al, 1997). In this respect WC is superior to TiC, as WC is perfectly wetted, while TiC is only moderately wetted by liquid steel as reviewed by Eustathopoulos et al (1999) and shown theoretically by Kaptay (2005).…”
