As a newly developed conductive ceramic with wide application prospects, the electrochemical corrosion behavior of Ti3SiC2 in 3.5% NaCl solution was investigated by potentiodynamic polarization, potentiostatic polarization and electrochemical impedance spectroscopy. Commercially pure titanium (CP Ti) was selected for comparative, and cooperated with XRD, XPS, SEM, the passivation behavior, corr...

This article is devoted to fabrication of gradient Ti3SiC2-based composites using preceramic papers as a feedstock. The initial raw material stack paper with Ti3SiC2 powder filler, the content which varies from 60 90% every three layers. were obtained by spark plasma sintering (SPS) method at 10 MPa pressure for min holding time. temperature was 1250 °C. microstructure and phase composition ana...

This study aims to investigate the microstructure and mechanical properties of Ti3SiC2-carbon nanofiber (CNF) composite materials by powder metallurgy (PM). Ti, SiC, graphite CNF powders were used produce Ti3SiC2-CNF materials. After formulated ground in a ball mill, milled pressed at 500 MPa pressure then sintered 1150 °C, 1300 °C 1450 °C. SEM-EDS XRD analysis examine phase formation. Hardness...

Incorporation of layers of noble metals in non-van der Waals layered materials may be used to form novel layered compounds. Recently, we demonstrated a high-temperature-induced exchange process of Au with Si in the layered phase Ti3SiC2, resulting in the formation of Ti3AuC2 and Ti3Au2C2. Here, we generalize this technique showing that Au/Ti2AlC and Au/Ti3AlC2 undergo an exchange reaction at 65...

In order to clarify plastic deformation behavior and mechanism of fracture energy absorption Ti3SiC2, Vickers indentation tests were conducted for Ti3SiC2 sintered bodies with various textured orientations. Textured fabricated by slip casting in a strong magnetic field spark plasma sintering (SPS), their orientation distribution analyzed SEM/EBSD. It was found that the around indents such as an...
