Microstructure and Tribological Performance of TiB2-NiCr Composite Coating Deposited by APS
Nickel chromium (NiCr) powders with different titanium diboride (TiB2) additions (20, 40 and 60 wt %) were prepared with a mechanical alloying method and then sprayed using an air plasma spraying technology. The microstructure and phase composite of the powders and the cross-sections of deposited coatings were analyzed with a scanning electronic microscope and X-ray diffraction. The tribologica...
متن کاملMicrostructure of spark plasma sintered TiB2 and TiB2–AlN ceramics
In this research study, the effects of aluminum nitride (AlN) additive on the densification behavior and microstructure development of titanium diboride (TiB2) based ceramic matrix composite were investigated. In this way, a monolithic TiB2 ceramic and a TiB2–5 wt% AlN ultrahigh temperature ceramic composite were fabricated by spark plasma sintering (SPS) proces...
متن کاملMicrostructure Evolution and Mechanical Properties of Al-TiB2/TiC In Situ Aluminum-Based Composites during Accumulative Roll Bonding (ARB) Process
In this study, a kind of Al-TiB₂/TiC in situ composite was successfully prepared using the melt reaction method and the accumulative roll-bonding (ARB) technique. The microstructure evolution of the composites with different deformation treatments was characterized using field emission scanning electron microscopy (FESEM) and a transmission electron microscope (TEM). The mechanical properties o...
متن کاملEffect of Ni content on the reaction behaviors and microstructure of TiB2-TiC/Ni cermets synthesized by MASHS
In this paper TiB2-TiC/Ni cermet with various Ni (20, 40 and 60 wt %) content were synthesized by mechanically activated self-propagating synthesis (MASHS) and effect of the addition of Ni on synthesis parameters and microstructure of synthesized samples were investigated. First raw materials (B4C, Ti and Ni) milled in Ar atmosphere. Then milling powders analyzed by XRD. In next step powders sy...
متن کاملStudy on the Impact Resistance of Bionic Layered Composite of TiC-TiB2/Al from Al-Ti-B4C System
Mechanical property and impact resistance mechanism of bionic layered composite was investigated. Due to light weight and high strength property, white clam shell was chosen as bionic model for design of bionic layered composite. The intercoupling model between hard layer and soft layer was identical to the layered microstructure and hardness tendency of the white clam shell, which connected th...
