“…Because of the difference in the thermal expansion coefficient between the newly formed phase and the original coating, stress concentration would be introduced on the coating surface, causing a change in the stress distribution, leading to locally high stress, which would easily induce thermal fatigue cracks [36]. At the same time, owing to the different structures and properties of the brittle oxide from the original coatings, it is prone to cracking or peeling under high temperatures and stresses, forming surface defects or small cracks [37]. These surface defects or cracks become the starting point for the generation of thermal fatigue cracks in the coating.…”

Three Ni-based alloys (Ni60, Ni65, Ni60W) were selected to be coated on the surface of 40Cr and 20 steel. The microstructure, phase composition and elemental distribution of the coatings were characterised respectively to discuss the effects of different substrates, cladding materials, and preparing processes. The corrosion and thermal fatigue behaviour of the coatings were investigated. The results show that the coatings prepared by plasma cladding have a dense microstructure with few defects and a white bright band of a certain thickness was formed between the coating and the substrate. The white bright band between the coating prepared by flame spraying and the substrate was not obvious. The main phase compositions of the coatings are Cr23C6, Cr7C3, Ni2.9Cr0.7Fe0.36 and FeNi3 phases, with the W2C phase also present in the Ni60W coating. The heat-affected zone (HAZ) of the coating is influenced by the coating preparing processes, substrate material and process state of substrates: the size of the HAZ of the plasma cladded coating is smaller than that of the flame sprayed coating, the HAZ of the 40Cr substrate is smaller than that of the 20 steel, and the HAZ of the tempered 40Cr substrate is smaller than that of the annealed 40Cr substrate. The Ni-based alloy coating can effectively improve the surface hardness of the substrate. The Ni65 alloy powder is the most effective (HV0.5992), followed by the Ni60W alloy powder (HV0.5798) and finally the Ni60 alloy powder (HV0.5712). The Ni65 alloy coating has the relatively best thermal fatigue properties, followed by the Ni60W alloy coating and the Ni60 alloy coating is the relatively worst. At the same time, the corrosion resistance of different Ni-based alloy coatings is consistent with the thermal fatigue properties of the coatings.

“…Research found that the hardness of the whole material can be increased by 8% with the addition of WC, which can be caused by a variety of reasons. Firstly, the small thermal conductivity (25 W/(m•k)) of TiC leads to a large temperature gradient [74], the addition of tungsten carbide (100 W/(m•K)) can promote the uniform distribution of temperature [75]. As a secondary carbide, tungsten carbide can also improve the wettability and sintering property of titanium (carbon, nitrogen)-based cermet, and inhibit the grain growth [76].…”

TiC ceramics have become one of the most potential ultra-high temperature structural materials, because of its high melting point, low density, and low price. However, the poor mechanical properties seriously limit its development and application. In this work, this review follows PRISMA standards, the mechanism of the second phase (particles, whiskers, and carbon nanotubes) reinforced TiC ceramics was reviewed. In addition, the effects of the second phase on the microstructure, phase composition and mechanical properties of TiC ceramics were systematically studied. The addition of carbon black effectively eliminates the residual TiO2 in the matrix, and the bending strength of the matrix is effectively improved by the strengthening bond formed between TiC; SiC particles effectively inhibit the grain growth through pinning, the obvious crack deflection phenomenon is found in the micrograph; The smaller grain size of WC plays a dispersion strengthening role in the matrix and makes the matrix uniformly refined, and the addition of WC forms (Ti, W) C solid solution, WC has a solid solution strengthening effect on the matrix; SiC whiskers effectively improve the fracture toughness of the matrix through bridging and pulling out, the microscopic diagram and mechanism diagram of SiC whisker action process are shown in this paper. The effect of new material carbon nanotubes on the matrix is also discussed; the bridging effect of CNTs can effectively improve the strength of the matrix, during sintering, some CNTs were partially expanded into GNR, in the process of crack bridging and propagation, more fracture energy is consumed by flake GNR. Finally, the existing problems of TiC-based composites are pointed out, and the future development direction is prospected.

“…Although laser cladding technology can achieve high deposition rates, it is hampered by expensive equipment, challenging operations, low production efficiency, and higher cladding costs [26][27][28]. In comparison, HIC offers advantages such as precise control, environmental friendliness, high heating efficiency, lower operational complexity, lower repair costs, and strong bonding between the cladding and the substrate [29][30][31][32].…”

To quickly repair the inner-surface damage to the hydraulic support cylinder caused by frequent scratches, corrosion, and wear in the process of fully mechanized coal mining, this paper proposes a method of high-frequency induction cladding (HIC) copper alloy on inner-wall of cylinder (IWC) to improve the corrosion, sealing and pressure retention performance of hydraulic cylinders combined with numerical simulation and experimental study. Firstly, a numerical temperature field model for HIC of copper alloy on the IWC is established to investigate various distribution patterns and influencing factors including frequency of induction heating, gap between coil and cladding, power supply rating, cladding thickness and side length of square section of induction coil, etc. Subsequently, an HIC test experiment is conducted to rigorously validate the numerical temperature field model and the experiment employs a meticulously collected dataset of temperature measurements, confirming the model’s accuracy and consistent alignment with anticipated changing trends. In addition, the experiment results were verified through microstructure observation, microhardness testing, friction-wear testing, and electrochemical corrosion parameters, which shows that the factors of induction heating frequency and others have obvious effects on the temperature field distribution of HIC copper alloy on the IWC. Under these working conditions (cladding thickness 1.5 mm, power supply rating 120 kW, heating frequency 120 kHz, gap between the cylindrical workpiece and the induction coil 3 mm, induction coil cross-sectional side length of 10 mm), the thermal impact on the cylinder barrel matrix is minimal, the metallurgical bonding between the cladding layer and the matrix is good, and there are no over burning and porosity defects.
