“…The deposition of diamond particles was followed by drying at room temperature for 24 hours. After drying, the samples were placed inside a vertical graphite crucible reaction chamber for subsequent SiC coating by CVD process using Methyltrichlorosilane (CH 3 SiCl 3 , MTS), hydrogen (H 2 ), and argon (Ar) at 1100°C for 5 hours, as described in our previous articles …”

The thickness of the SiC/diamond composite coating was directly measured by SEM.…”

“…The SiC film is usually prepared by chemical vapor deposition (CVD) that not only largely contributes to the overall wear resistance of the structure but also offers great affinity to substrate . Alternatively, an even layer of diamond particles (average size >30 μm) is fixed on the graphite surface through PVA glue . However, electrophoretic deposition (EPD) is considered to be an effective technique for the deposition of finer diamond particles on the graphite substrate …”

In this research, SiC/diamond composite coatings were fabricated by a novel procedure that consisted of the electrophoretic deposition (EPD) of diamond particles onto graphite substrates followed by chemical vapor deposition (CVD) of SiC. Various concentrations of MgCl2 were employed to increase the deposition rate and uniformity of the deposits during the EPD process by giving a positive charge to diamond particles. The CVD of SiC was found to have a tightly connected diamond‐graphite interface and spherical texture. With higher weight fraction of diamond particles deposits, the wear of steel ball increased, while the wear of SiC coating decreased.

In air and railway transportation, corrosion and wear lead to the rapid failure of equipment. Epoxy (EP)-based coatings are widely used in research on the anti-corrosion of organic coatings, but their application as materials for wear resistance is limited due to their non-abrasive properties. In this study, a novel high-performance epoxy-based composite coating was developed through the self-assembly of silicon carbide (SiC) and graphene oxide (GO) and the tuning of the interfacial structure with epoxy resin. The coatings were comprehensively characterized, including their electrochemical behavior, a salt spray test, and friction and wear experiments, and the optimal addition ratio of SiC-G@GO (SiC-G@GO was prepared by the self-assembly of γ-(2,3-epoxypropoxy) propytrimethoxysilane (KH560)-modified SiC (SiC-G) on the surface of GO sheets) in the epoxy coatings was explored. Benefiting from the labyrinth effect and their rolling-friction-like microstructure, the 1 wt% SiC-G@GO/EP coating exhibits excellent wear and corrosion resistance. Compared with pure epoxy resin, the 1 wt% SiC-G@GO/EP coating increased by 4 orders of magnitude after 10 days of immersion. The average friction coefficient was 41.5% lower than that of the pure EP coating, and the wear rate was 56.6% lower. This research has positive implications for the development and application of anti-corrosion and wear-resistant organic coatings.

This study fabricates certain Ni/diamond composite coatings using a coelectrodeposition method and then evaluates the effect of diamond content on the morphology, phase structure, microhardness, wear, and corrosion resistance of such coatings, while exploring their tribological and anticorrosion mechanisms. It is demonstrated that the addition of diamond can change the preferred orientation of Ni from (200) to (111), and its texture coefficient value can be boosted from 23.3% to 64.4% with the increase of diamond content. In the experiment, at a diamond content of 3 g L−1, the deposited diamond particles are more and evenly dispersed across the composite, with the microhardness of nickel‐based coatings reaching an optimum value of 613 HV. In addition, the coefficient of friction is reduced to a minimum value of 0.627, while the wear rate is kept at only 1.79 × 10−5 mm3 Nm−1, indicating a high wear resistance. Electrochemical test results demonstrate that the Ni/diamond composite coatings produced at 3 g L−1 create the maximum charge transfer resistance (5429.3 Ω cm2) and the minimum corrosion current density (2.19 μA cm−2), features that can deliver the best corrosion resistance.
