“…Two methods were employed to obtain composites with different distribution states of TiB 2 : (1) conventional extrusion (CE) and (2) powder metallurgy (PM). More details of the fabrication processes can be found in our previous studies [38][39][40]. The composites obtained by the CE method had a lot of TiB 2 stripes distributed along the extrusion direction, while those from the PM method exhibited uniform TiB 2 particle distribution.…”

“…The entire process was carried out in constant voltage mode with 20 V. The anodization time range was from 15 to 60 min and a sulfuric acid electrolyte with a concentration of 197 g/L was used for the anodic oxidation treatment. The sealing treatment was performed for 5-15 min using potassium dichromate with a concentration of 100 g/L at a temperature range of 95-100 • C. studies [38][39][40]. The composites obtained by the CE method had a lot of TiB2 stripes distributed along the extrusion direction, while those from the PM method exhibited uniform TiB2 particle distribution.…”

In this study, the effects of particle distribution and anodizing time on the microstructure and corrosion resistance of the TiB2 particle-reinforced Al-Zn-Mg-Cu composite were investigated. Relationships between TiB2 particle distribution, anodizing time, coating growth rule, and corrosion resistance were characterized and discussed using an optical microscope, a scanning electron microscope, an electrochemical test, and a salt spray test. Dispersion of TiB2 particles by powder metallurgy improved the corrosion resistance of the anodized coating on composites. Compared with the matrix, the corrosion potential (Ecorr) of the anodized coating shifted to the positive direction, and the corrosion current density (icorr) decreased. Meanwhile, the icorr of the coating decreased initially and then increased with the extension of the anodization time. The corrosion resistance of the coating was optimal at an anodization time of 20 min. The corrosion resistance of the composite was determined by both the porosity and thickness of the coating. Additionally, all samples treated by potassium dichromate sealing had no corrosion points after a 336-h salt spray test, demonstrating an excellent corrosion resistance suitable for harsh environmental applications in industry.

Brazing of carbon–carbon (C/C) composites with metallic materials currently faces a series of difficulties, such as the poor wettability of metallic materials on the surface, the nanoscale interface bonding of C/C composites and metallic materials, thermal stress problems for these different materials, etc. Especially, the practical problems, including the low joint strength and insufficient reliability, still limit the large-scale practical application of brazing technology for C/C composites and metal materials. Herein, in order to guide the fabrication of high-quality joints, we present a brief discussion on the latest research progress in the joints of C/C composites and metallic materials, including current challenges, solution methods, mechanisms, and future prospects. More importantly, the nanoscale interface in the carbon–carbon composites and metallic alloys is paid very little attention, which has been critically discussed for the first time. Then, we further outline the possible solutions in joint problems of C/C composites and metallic materials, proposing feasible strategies to control the reaction in the brazing process, such as surface treatments, the addition of reinforcing phases, a transition layer sandwiched between the base material and the intermediate layer, etc. These strategies are being envisioned for the first time and further contribute to promoting the converged applications of C/C composites and metallic materials.
