“…The addition of GO reduces defects and prevents corrosive media from entering the composite coating, then the composite coating has excellent anti-corrosion performance [39]. Research has shown that nano-TiC is highly stable, and when combined with a pure nickel coating, the grains are refined, coating defects are reduced, and no obvious microcracks appear [8]. Then nano-TiC protects the Ni-TiC composite coating from corrosive solutions.…”

“…The common nanoparticles involved in nickelbased composite coatings mainly include nano-SiC [6], Al 2 O 3 [7], TiC [8], ZrO 2 [9], La 2 O 3 [10] and diamond [11], carbon nanotubes [12], graphene [4] and graphene oxide [13]. Research has shown that adding a small amount of graphene oxide (GO) can significantly improve many properties of the nickel composite coating, such as elastic modulus, electrical conductivity, yield strength, friction reduction, wear resistance, and corrosion resistance [13][14][15][16].…”

The Ni-GO-TiC nano-composite coating was prepared by scanning jet electrodeposition. The morphologies and microstructures of the composite coating were analyzed by FESEM and XRD, and the wear and corrosion resistance of the composite coating were studied. Studies have shown that the Ni-GO-TiC composite coating has a micro-nano ridge shape structure. The addition of nano TiC and GO does not change the structure but refines the grain growth of the Ni matrix metal. Nano TiC can effectively prevent GO from agglomerating, improve the dispersion, and further enhance the wear resistance of the Ni-GO-TiC composite coating. In addition, the corrosion resistance of the Ni-GO-TiC composite coating has also been greatly improved. Compared with pure Ni coating, the corrosion current density is reduced from 51.30 μA·cm-2 to that of the Ni-GO-TiC composite coating to 1.712 μA·cm-2. Nano-TiC and GO are used as reinforcing phases to refine the grains of the composite coating and effectively inhibit the penetration of corrosive media.

This study focuses on enhancing surface hardness and wear resistance through microwave-assisted cladding of a Ni-TiC mixture onto SS-304 substrates. Meticulous preparation steps were employed, including substrate cleaning and preheating of the coating material, to ensure optimal adhesion and prevent defects. Microwave hybrid heating (MHH) was utilized to facilitate rapid and uniform heating, enhancing the efficiency of the coating process. A scanning electron microscope (SEM) image revealed a uniform cladding layer devoid of cracks, indicating successful deposition and consolidation. Surface hardness was improved by 46.87%, demonstrating a significant enhancement in mechanical properties. The measured wear rate and coefficient of friction provided critical insights into the surface’s wear resistance and frictional behavior. Overall, this study highlights the efficacy of microwave-assisted cladding in improving the performance and durability of SS-304 substrates, with implications for various engineering applications requiring enhanced surface protection and mechanical properties.

“…For this reason, one of the main objectives of the study is to develop a theoretical and practical basis for the development of technology for obtaining metals that meet the specific requirements of the existing industry, and at the same time having a relatively low cost. The solution to this problem is the rational design of steels by providing the necessary properties only to those amounts of metal that are subjected to specific effects, which is achieved by using a small amount of properly selected ultradisperse powders (Brown, 2014;Camagu, 2020;Parashivamurthy, 2014;Sobula, 2017;Zhang, 2015), and their location in specified volumes -on the working surface or in other volumes of the product that need specific properties. In other words, this can be characterised as the creation of materials with a controlled gradient of properties (Fernandes, 2017;El-Hadad, 2011;Kiviö, 2016;Watanabe, 2009Watanabe, , 2017.…”

Metallurgy and engineering endeavours to develop and implement advanced technologies to save metal and create new metallic materials with improved characteristics. These scientific and technological activities include improvements to existing materials as well as the development of new materials by various methods. One such method is the creation of iron-based materials with a gradient of properties along the cross-section, obtained by locally modifying a given volume of the formed billet by filling the structure with heat-resistant, high-strength, dispersed phases. This paper describes the course and results of a number of experiments on the formation of a gradient of properties in steel castings of various compositions, and analyses the results of experiments on the creation of such materials.
