Abstract. Nanocomposite coatings combining hard phases (TiB2, TiC) with amorphous carbon (a-C) were developed to provide a good compromise between mechanical and tribological properties for M2 steels used in a wide variety of applications such as cutting tools, bearings and gear mechanisms. Comparative Study of Physical, Mechanical and Tribological Jul 10, 2020 · Enhanced mechanical and tribological properties were observed for both the prepared composites compared to Al2024 alloy; this increment was higher for Al2024-TiB2 composite than Al2024-SiC composite. Al2024-TiB2 composite exhibits superior wear resistance with non-existence of plastic deformation and adhesion on the wear tracks.
Apr 03, 2018 · (Ti,Mo)C, TiB 2, and Mo 2 B particles reinforced Fe-based composite coatings were fabricated by laser cladding process. The effects of Molybdenum (Mo) on the microstructure and wear properties of the coatings were investigated. The results show that block-like or cuboidal TiB 2, Mo 2 B and flower-like (Ti, Mo)C ceramics reinforcements were formed in the coatings. Effect of TiB2 on the Phase Composition, Microstructure Mar 11, 2021 · Besides SiC, TiB 2 is also considered as potential reinforcing agent due to its excellent mechanical properties (hardness:~30 GPa, elastic modulus:~550 GPa, and flexural strength:over 500 MPa), high temperature stability (melting point 3225°C), high oxidation and corrosion resistance, and good thermal and electrical conductivity (60120 W · m 1 · K 1 and 10 6 S · cm 1, respectively)
Jan 27, 2021 · In this study, three different amounts of HTCs (0.25, 0.50, and 1.00 wt.%) produced from cellulose were used as a reinforcement material in Al 7075 by powder metallurgy for the first time. According to the mechanical, tribological, and corrosion test results, all of the mentioned properties of Al 7075 alloy were improved by reinforcing with HTCs. Mechanical and Tribological Properties of Spark Plasma Aug 22, 2017 · The effects of sintering temperature on densification and mechanical properties of composites have been investigated in detail. SiCTiB 2 and SiCTiB 2 TaC composites sintered at 2100°C showed high Vickers hardness value, i.e., 27.20±1.23GPa and 26.40±0.80GPa, respectively, under 1 kgf (9.81N) load.
Aug 23, 2020 · particles and the matrix, thereby improving the tribological properties. However, the WC particles are prone to settle at the bottom of the composite coating under a too low cooling rate, and the tribological properties deteriorate instead. TiB2 particles have high hardness, and excellent resistance to wear, oxidation and corrosion, Processing and characterization of the microstructure and Jun 05, 2021 · In the present research, aluminum metal matrix composites were processed by the stir casting technique. The effects of TiB2 reinforcement particles, severe plastic deformation through accumulative roll bonding (ARB), and aging treatment on the microstructural characteristics and mechanical properties were also evaluated. Uniaxial tensile tests and microhardness measurements
