“…Titanium as matrix material not only had long service life, good chemical stability, but also had relatively low price [28]. Iridium was one of the coating material mixtures, and iridium metal had good ductility [29]. Ru was also widely applied in overlay materials, and its metal had excellent the surface area of the coated electrode and enhanced the reaction efficiency and electrode utilization [26].…”

In this study, the preparation characteristics of coated electrodes were used to remove organic matter from wastewater. The effects of low concentration range in different current densities and pH on the removal of organic substances, chemical oxygen demand (COD) and ammonia nitrogen (NH 3 -N) by the coated electrode were explored. The experimental results indicated that the removal efficiency of NH 3 -N and COD achieved the optimum value when the electric current density was 8-10 mA/cm 2 , the pH value was mild alkaline or neutral, and the electrolysis time was about 30 min. The preparation process of coated electrode and the mechanism of degradation of organic matter in wastewater were investigated. The coated electrode was analyzed by blending Energy Dispersive X-Ray (EDX) and Scanning Electron Microscope (SEM). The results indicated that the titanium-based ruthenium coated electrode was more suitable for practical application.

“…[4][5][6][7][8] Carbon nanotube can be a potential reinforcement of high-performance metal matrix composites (MMCs) due to their variety of excellent properties. [9][10][11][12] However, it has been reported that there is difficulty in dispersing CNT uniformly in the matrix. CNT agglomerates in a state where tubes are entangled with each other due to strong π-π interaction and van der Waals force.…”

This study aims to strengthen carbon nanotube (CNT)/Al composites, which were fabricated by a combination of spark plasma sintering (SPS) and repeated hot rolling techniques. Dry ball milling was conducted to uniformly disperse CNT in Al powders. The microstructures of the CNT/Al composites including dispersibility of CNT were observed using a scanning electron microscope (SEM) and transmission electron microscope (TEM). Ball milling treatments promoted to reduce the number of CNT aggregations and increase C concentrations in the CNT aggregations in the composites. Anisotropic tensile behavior was also investigated, which demonstrated that the post-SPS repeated hot rolling can highly enhance the tensile strength as well as deformability of the composites.

“…The formation of nickel–phosphorus coating on graphene by electroless plating is a common and effective method. [ 21 ] Mu et al [ 22 ] found that graphene in the composite material had good dispersion and interface bonding due to the dense nickel coating on the surface of the graphene. The interfacial TiC X –Ti 2 Ni formed between Ni‐GNFs and matrix greatly improves the interface load transfer capability of composites ( σ b = 793 MPa).…”

Herein, the nickel–phosphorus‐coated graphene nanoflakes/Ti6Al4V composites (Ni‐P@GNFs/Ti6Al4V composites) are fabricated by spark plasma sintering (SPS) and hot isostatic pressing (HIP), respectively. The results show that the Ni‐P@GNFs/Ti6Al4V composites prepared by SPS, in which the agglomeration of Ni‐P@GNFs is weak and the size of α phase is small, possess improved mechanical properties relative to those of the Ni‐P@GNFs/Ti6Al4V composites prepared by HIP. The compressive yield strengths of Ni‐P@GNFs/Ti6Al4V composites prepared by SPS enhance from 1116.29 MPa (0 wt% GNFs) to 1367.33 MPa (1 wt% GNFs), and microhardness increases from 302.83 to 479.43 HV. The Ni‐P@GNFs/Ti6Al4V composites prepared by HIP reach a yield strength of 1299.59 MPa and microhardness of 410.10 HV. In addition, serious agglomeration of GNFs leads to a significant drop in ductility (from 47.47% to 25.76%) in the Ni‐P@GNFs/Ti6Al4V composites prepared by HIP.
