“…Figure 1 shows the flow chart for the preparation process of NST via LMD. Referring to relevant studies [21][22][23], the optimum process parameters for LMD obtained after multiple parameter tests are listed in Table 3. According to the lubricant addition ratios and LMD process parameters, the NBA, NST, NT and NS samples were prepared using 3D printing equipment (RC-LDM-8060, Nanjing Yuchen Laser Technology Co. Ltd., Nanjing, China).…”

As a high-temperature structural material, Ni3Al matrix composites are often used to manufacture basic mechanical components that need to be used in high-temperature conditions. To meet the increasing demand for metal matrix composites with an excellent tribological performance over a wide temperature range, Ni3Al matrix self-lubricating composites containing Sn-Ag-Cu and Ti3SiC2 (NST) were synthesized via laser-melting deposition. Dry sliding friction tests of NST against Si3N4 ball were undertaken from 20 to 800 °C to investigate the tribological behavior and wear-triggered self-healing properties. The results show that the tribological behaviors of NST are strongly dependent on the testing temperature and self-healing properties. At low and moderate temperatures from 20 to 400 °C, as the Sn-Ag-Cu flows into the cracks and is oxidized during sliding friction, while the cracks on the worn surface are filled with oxides consisting mainly of Al2O3, SnO2 and CuO. At higher temperatures of 600 and 800 °C, the cracks are filled by the principal oxides of Al2O3, TiO2 and SiO2 due to the partial decomposition and oxidation of Ti3SiC2. Compared with other testing temperatures, the recovery ratio relative to the Ni3Al base alloy of the cracks on the worn surface of NST is the highest at 400 °C, which is about 76.4%. The synergistic action mechanisms of Sn-Ag-Cu and Ti3SiC2 on the crack self-healing from 20 to 800 °C play a significant role in forming a stable solid lubricating film, improving the anti-friction and wear resistance of NST. The results provide a solution allowing for metal matrix composites to achieve excellent lubrication stability over a wide temperature range by virtue of the crack self-healing properties.

“…Therefore, powder‐based additive manufacturing of Ni 3 Al superalloys was the first to conduct research. Huang et al [ 13 ] deposited a Ni 3 Al superalloy wear‐resistant layer on the 316 L stainless steel using laser melting Ni 3 Al powder. By direct laser deposition, Liu et al [ 14 ] deposited a single‐crystal (SX) Ni 3 Al‐based IC221W superalloy on an SX Ni‐based superalloy substrate but found solidification cracks at the interface of the deposited alloy and substrate.…”

In‐situ synthesis of Ni3Al by simultaneously feeding both Ni and Al wires into the molten pool is a common wire‐based additive manufacturing technology for Ni3Al superalloys. However, Ni3Al superalloys within a composition gap still have not yet been synthesized. The optimal composition range has also not been investigated yet. Herein, Ni3Al superalloys with Al equivalents between 17‐25 at.% were fabricated by twin wire‐based direct arc energy deposition by adjusting the relative feeding speed. Microstructural analysis showed that the solidification products generated no γ' precipitation when Al content was 17 at.%. Al is a strong γ'‐forming element, as the Al content increased, the deposited Ni3Al superalloys with 20‐25 at.% Al consisted of dendritic γ + γ' dual‐phase and interdendritic γ' single‐phase. The proportion of γ + γ' dual‐phase gradually increased with decreasing Al contents. Whereas the tensile strength and elongation gradually increased. The Ni3Al superalloys (20 at.% Al) with the most γ + γ' dual‐phase exhibited the highest tensile strength and elongation (939 MPa and 25.7%, respectively). Fracture analysis showed that the dislocation decomposition and stacking fault shearing mechanisms allowed dislocations to continuously cut through γ' precipitations to maintain deformation, which was responsible for high tensile strength and ductility.This article is protected by copyright.

“…The Ti 3 SiC 2 contents in the lubrication layer, middle layer and substrate layer of Ni 3 Al-GCS were designed to be 12.0, 9.0 and 6.0 wt.%, respectively [29]. In addition, the laser power, laser scanning rate and other LMD parameters have important effects on the mechanical property and tribological performance of Ni 3 Al matrix self-lubricating composites [30]. Based on relevant studies [26,31], after multiple LMD tests, the optimum technological parameters were as follows: laser power, 2000 W; scanning velocity, 7.2 mm s −1 ; spot diameter, 6 mm; scanning distance, 3 mm; layer thickness, 0.1 mm.…”

As the contact part of metal-matrix self-lubricating composites during sliding friction, the friction interface layer directly affects the tribological performance of the material. However, the formation of the friction interface layer with outstanding tribological performance is limited by the friction conditions during sliding friction. To address this problem, based on the antifriction and wear resistance mechanisms of the in-situ formed friction interface layer of Ni3Al matrix self-lubricating composites (NMSCs) with homogeneous solid lubricant, Ni3Al matrix self-lubricating composites with a gradient composite structure (Ni3Al-GCS) were prepared via laser melt deposition, in which each component layer contained different contents of Sn-Ag-Cu and Ti3SiC2. Dry sliding friction tests of Ni3Al-GCS against GCr15 steel balls were performed under different loading conditions. The results showed that the tribological performances of Ni3Al-GCS in the range of 4–16 N were less affected by the variation of the loading conditions than those of NMSCs. The gradient composite structure of Ni3Al-GCS could reduce the dependence of the tribological behavior on the friction conditions, resulting in excellent antifriction and wear resistance of Ni3Al-GCS in a wide load range. In addition, the gradient composite structure could reduce the sliding contact damage of the friction contact surface of Ni3Al-GCS, and contribute to the formation of friction interface layer rich in the lubrication phase and oxides, thus improving the tribological performance of Ni3Al-GCS during sliding friction. This study provides new approaches for the tribological design of metal-matrix self-lubricating composites in a wide load range.
