Presentation Title L-185: Nanocomposites Ti/B/TiO2 by Mechanical Alloy Synthesis
Author(s) Diana Maqueda Jaramillo
On-Site Speaker (Planned) Diana Maqueda Jaramillo
Abstract Scope The TiB2 cermet material, composed of a ceramic element (Boron) and a metallic (Titanium) it has properties as: hard wear resistant, relatively high fracture toughness, good electrical conductivity and excellent chemical resistance. These properties and characteristics depend of reagents nature, powders purity, and synthesis technique. Being the mechanical alloying an efficient technique for composites synthesis, this because is a simple and inexpensive processing method. Is a recently solid-state powder processing techniques involving repeated welding, fracturing and rewelding of power particles in high-energy ball milling, with few variables, as: powders/ball ratio, rate and time grinding, process control agent, mill. In this work we focus the TiB2 synthesis and its formation and evolution of TiB2 phase. This evolution could be by the effect of oxidation-reduction reaction occurred among TiO2, TiB2, Ti, and B by high-energy milling; opposed to the Ti/B mix, where the formation of TiB2 is slow and inefficient
