Producing Cu-TiB2 Nano Composite Using Powder Metallurgy Route and Study on its Mechanical and Physical Behavior, M.Sc. Thesis Sharif University of Technology ; Pourazrang, Kazem (Supervisor) ; Abachi, Parvin (Supervisor)
Abstract
In applications such as high duty sliding contacts and other electrical components requiring good electrical- and thermal-conductivity, proper mechanical wear resistance in combination with arc erosion resistance are required.The Cu/TiB2 nano-composite seems to be a good candidate for such cases. At present work TiB2 nano-particles has been selected as reinforcement, due to its valuable properties, i.e., high melting point (2850 - 2900 °C), low linear CTE (8.10 µmm-1 °C-1), thermal conductivity (60.0 - 120 W/m-K) as well as low specific electrical resistivity (10 - 30 μΩ.cm) and high hardness (25-35 GPa HV). Additionally, there are limited articles which have focused on evaluation of...
