“…A good amount of interfacial bonding is found between the Cu and ceramic reinforcements which thus accounts for an increased hardness of sample with a modest concentration of Gr.-TiC. [24][25][26] Figure 14 displays the compressive strengths of different specimens (Pure Copper and Composites) as a function of the concentration of Gr.-TiC. Specimen having 5 wt.% of Gr.-TiC shows the highest value of compressive strength, and it gradually reduces with an increase in Gr.-TiC reinforcement, as shown by the experimental data.…”

In the present paper, powder metallurgy (P/M) was employed to create copper matrix composites reinforced with Graphite (Gr.)-Titanium Carbide (TiC) [at 5, 10, and 15 wt. %]. Both Gr. and TiC was used in equal concentration as reinforcements. For this experiment, cylindrical specimens with approximate dimension of 30 mm in length and 10 mm in dia. were created by compacting milled powders under pressure of 540 MPa for 2 minutes. Green shaped cylindrical specimens were held at 900, 950, and 1000 degrees Celsius for 2 hours at the maximum temperature. Composite samples were tested for hardness and compressive strength. Specimens' microscopic structures were studied with the help of a variety of analytical tools, including an optical microscope, SEM, and EDS. In composites having copper matrix, reinforcement phase was found to be uniformly dispersed throughout the material. Compression strength in composites was increased by about 108% at 5 wt.% of Gr.-TiC reinforcement and by about 34% at 10 wt.% of reinforcements (Gr.-TiC). When Gr.-TiC reinforcement was added to a copper matrix at a weight percentage of 15 wt.%, the compression strength significantly decreased. The wear property of the produced composites was enhanced by including Gr.-TiC reinforcement into the copper matrix.

In recent years, there has been notable exploration and investigation of graphene nanocomposites (GNCs) through experimental, numerical, and computational methods. GNCs have gained attention due to their remarkable mechanical and thermal properties, particularly when Gr has been utilized as the reinforcing material. Gr, a two-dimensional material, possesses exceptional properties, including greater elastic modulus, thermal conductivity, and electrical conductivity. As a result, GNCs have emerged as promising materials for various applications in aerospace and automobiles. Computational techniques, including finite element method (FEM), molecular dynamics, and Monte Carlo analysis have been utilized to analyse different aspects of GNC. Among these, FEM stands out for designing and evaluating the mechanical properties of GNC, enabling researchers to simulate and analyse the characteristics of GNC structures under diverse loading conditions, optimizing their design and predicting mechanical performance. This review emphasizes the significance of Gr in various matrices, discusses the present cutting-edge status of FEM methodologies for Gr reinforcement, and highlights its advantages and purposes. Furthermore, it explores the governing parameters affecting the mechanical properties of GNC and briefly presents the different mechanical properties of NC. We also outline future research directions and potential applications of GNC for advancing future generations of materials.

In coal based thermal power plant, the boiler components (superheater, combustion chamber, superheater tubes, boiler walls, reheater etc.) are subjected to harsh environment characterized by high temperatures, aggressive combustion products, and abrasive particles. Corrosion, erosion, and oxidation relentlessly reduce their lifespan and efficiency, posing significant economic and safety concerns. This review explores the potential of surface modification techniques to act as a valiant shield against these destructive forces, extending the life, enhancing the performance, and ensuring the safe operation of boiler components. In this articles various surface modifications techniques including their merits and demerits are discussed with emphasis on thermal spray techniques. From established methods like thermal spraying and laser cladding to innovative approaches like nanocoatings and electrochemical treatments, each technique is meticulously examined for its effectiveness in boosting corrosion resistance, mitigating erosion wear, and minimizing oxidation at crucial boiler locations. This review culminates in a compelling vision of the future, where sophisticated surface modification techniques become an integral part of boiler design and maintenance strategies. By harnessing the power of these technologies, we can usher in an era of more efficient, reliable, and sustainable boiler operation, safeguarding investments and protecting the environment.
