Ti3SiC2/Al2O3 multilayered composites were prepared by the combination of tape casting and hot pressing sintering. The slurry was produced by adjusting the amounts of each organic material, including triethyl phosphate (TEP) as a dispersion, polyvinyl butyrate (PVB) as a binder, dioctyl phthalate (DOP) as a plasticizer, and anhydrous ethanol as an organic solvent. When TEP content was 3 wt.%, PVB content was 4.5 wt.%, R‐value (DOP/PVB) was 1.4, and solid content was 38 wt.%; the cast film with a smooth surface, good flexibility, and uniform thickness was obtained after defoaming, tape casting, and drying. Three samples were prepared, namely, S1–S3. The S1 was monolithic Ti3SiC2/Al2O3 (mass ratio is 1:1) composites. S2 and S3 were Ti3SiC2/Al2O3 multilayered composites, which matrix layers were Ti3SiC2/Al2O3 composites (mass ratio is 1:1) and Al2O3, respectively, and their interface layer was Ti3SiC2. S1–S3 were also sintered at 1550°C. The bending strength of multilayered materials were lower than that of monolithic material, but the fracture toughness of multilayered materials significantly increased. Due to the introduction of Ti3SiC2 interface layer, the friction coefficient and wear rate of Ti3SiC2/Al2O3 multilayered composites were reduced by 30.7% and 33.8%, respectively, compared with monolithic material.

“…In this work, the situation was different because the sample was Ti3SiC2 based-composite with 70 vol% of Ti3SiC2. At RT, comparatively, Ti3SiC2 and composites of Ti3SiC2 with 15vol% Ag, with 15vol% PbO, and with 15vol% PbO-15vol% Ag showed wear rates of 2 × 10 −3 mm 3 /(N•m), 3 × 10 −5 mm 3 /(N•m), 2 × 10 −4 mm 3 /(N•m), and 2 × 10 −4 mm 3 /(N•m), respectively, during sliding against Inconel 718 at 5N and 0.1 m/s [20,22]. These results showed that the incorporation of 15vol% Ag or 15vol% PbO or 15vol% PbO-15vol% Ag can decrease the wear rate of Ti3SiC2 by at least an order of magnitude at RT.…”

“…Pb is lubricous due to its low shear strength. In our previous work [21,22], we found that the incorporation of PbO (melting point: 888 • C) instead of Pb (melting point: 327 • C) in Ti 3 SiC 2 can successfully prepare Ti 3 SiC 2 /Pb composites and avoid the loss of Pb during the sintering process. The as-prepared composite showed better friction and wear behaviors than Ti 3 SiC 2 at elevated temperatures.…”

Ti3SiC2-PbO-Ag composites (TSC-PA) were successfully prepared using the spark plasma sintering (SPS) technique. The ingredient and morphology of the as-synthesized composites were elaborately investigated. The tribological properties of the TSC-PA pin sliding against Inconel 718 alloys disk at room temperature (RT) to 800 °C were examined in air. The wear mechanisms were argued elaborately. The results showed that the TSC-PA was mainly composed of Ti3SiC2, Pb, and Ag. The average friction coefficient of TSC-PA gradually decreased from 0.72 (RT) to 0.3 (800 °C), with the temperature increasing from RT to 800 °C. The wear rate of TSC-PA showed a decreasing trend, with the temperature rising from RT to 800 °C. The wear rate of Inconel 718 exhibited positive wear at RT and negative wear at elevated temperatures. The tribological property of TSC-PA was related to the tribo-chemistry, and the abrasive and adhesive wear.

“…The ternary carbide Ti 3 SiC 2 , one of the MAX phases, is of significant interest for its potential in tribological applications due to its remarkable combination of properties in damage tolerance, machinability, electric and thermal conductivity, self-healing capability, and lubrication [1][2][3][4][5][6][7]. However, the conditions allowing excellent tribological properties are limited to either high sliding speed or high temperature, which cause the formation of tribo-induced oxides on the contact interfaces [8][9][10][11][12][13][14][15]. The synthesized Ti 3 SiC 2 bulks restrict the potential for tribological applications in engineering components, whereas plasma spraying with a high spray temperature and a prominent deposition rate provides an efficient way to achieve these wear-resistant coatings of the MAX phase.…”

Torsional Fretting Wear Properties of Thermal Oxidation-Treated Ti3SiC2 Coatings

2018

In this study, efforts were made to oxidize the Ti3SiC2 coating surface to improve its wear resistance by producing oxide layers and healing microcracks that initiated from the thermal sprayed process. Tribological behaviors of the thermal oxidation-treated Ti3SiC2 coatings subjected to various temperatures (200, 300, and 400 °C) and durations (1, 3, and 5 h) were investigated comparatively by fretting wear. The results showed that the thickness of the oxide layer and the average content of element O on the surface were gradually increased with increasing temperature. Lower friction coefficients were observed in coatings at 200–400 °C for 1 h. Better performance of crack-healing features was demonstrated at 400 °C, whereas fresh microcracks were formed under the fretting condition due to the fragility of oxides at the same time. The tribological behavior of thermal oxidation-treated Ti3SiC2 coatings was mainly controlled by delamination and abrasive wear. The volume losses induced by wear scars decreased with the increase in oxidation time under the oxidation treatment at 200 °C and increased with increasing oxidation time under the oxidation temperatures of 300 and 400 °C.
