“…Considering the varying interaction of microwaves with materials, maintaining the material-specific skin depth at approximately 4.7 µm at 2.45 GHz was necessary to prevent direct particle-microwave interaction at room temperature. Microwave hybrid heating (MHH) using charcoal as a susceptor material overcame microwave reflection by rapidly heating the powder mixture [48]. To prevent contamination, a pure graphite sheet served as a separator between the susceptor and the powder mixture during MHH.…”

This study presents a revolutionary approach to surface enhancement through microwave-assisted cladding of a Ni and 15% BN particle mixture onto SS-304 substrates. Meticulous preparation steps were undertaken, including substrate cleaning and powder preheating, to ensure optimal adhesion and coating quality. Microwave hybrid heating using charcoal as a susceptor material facilitated rapid and uniform heating of the powder mixture, while a pure graphite sheet prevented contamination during the process. The experiment was conducted using a multimode microwave applicator at specific power and frequency settings, resulting in controlled heating for optimal coating formation. The precision of the microwave-assisted cladding process was illustrated through SEM images, revealing a uniform distribution of cladding particles across the substrate. Moreover, significant improvements in surface hardness and wear resistance were observed, with a 44.67% increase in surface hardness and a low wear rate of 0.0020 mm3/m. These findings highlight the effectiveness of the developed cladding technique in enhancing the mechanical properties and wear resistance of SS-304 substrates, paving the way for its potential application in various industries requiring reliable surface protection and durability under sliding contact conditions.

The present study focuses on achieving precise deposition of a Ni and 15% BaTiO3 particle mixture onto SS-304 substrates through meticulous preparation steps. Thorough cleaning of the SS-304 substrate eliminated contaminants, ensuring optimal adhesion. Simultaneously, the Ni-BaTiO3 mixture underwent preheating at 1200°C for 20 hours in a muffle furnace to eliminate moisture content, crucial for preventing coating defects. A uniform and crack-free cladding layer enhances the substrate’s resistance to wear, corrosion, and mechanical stresses, thereby extending its service life and improving overall functionality. The surface hardness of SS-304 experienced a substantial improvement of 39.90% following the cladding process with Ni and 15% BaTiO3. A sliding speed of 2 m/s was meticulously selected to replicate typical velocities encountered in practical applications, ensuring a realistic assessment of frictional behavior and wear resistance. Similarly, the sliding distance of 1000 m and an axial load of 5 N were precisely calibrated to simulate the mechanical stresses experienced during sliding contact, facilitating a thorough examination under relevant conditions. These carefully chosen parameters enabled the determination of key tribological properties essential for evaluating the performance of the cladded surface of SS 304 with Ni + 15% BaTiO3. The wear rate, measured at 0.0016 mm3/m, serves as a critical indicator, revealing the volume of material lost per unit distance of sliding. This parameter provides invaluable insights into the surface’s wear resistance and durability, crucial for assessing the longevity and performance of the cladded surface under abrasive conditions. Additionally, the coefficient of friction, determined to be 0.255, offers a quantitative measure of the surface’s frictional behavior during sliding contact.

Deposition of high entropy alloy FeCoNiMnCu on SS-304 was carried out by microwave energy for application in “solid oxide fuel-cell (SOFC) interconnects”. The ball-milling has been performed by taking “Fe, Co, Ni, Mn, and Cu” in equal 20 wt. % of before deposited on SS-304 substrate. The deposited steel with 20% Fe 20% Co 20% Ni 20% Mn 20% Cu high entropy alloy (HEA) was exposed to thermal-exposure in the air for up to 10 weeks at 800 °C. The uniform cladding distribution of 20% Fe 20% Co 20% Ni 20% Mn 20% Cu HEA particles can be apparently observed on SS-304 substrate by utilizing Scanning Electron Microscope (SEM), and Optical microscopy analysis. Homogeneity in the interfacial layer was evident by employing Scanning Electron Microscope (SEM) characterization. Results have indicated that after the thermal exposure of deposited steel with 20% Fe 20% Co 20% Ni 20% Mn 20% Cu in the air for up to ten weeks at 800 °C, a “protective Cr2O3 layer”, and “high-entropy spinel coating” of (Fe, Co, Ni, Mn, Cu)3O4 have been formed. During microwave cladding, the emergence of harder-phases has contributed to the raised hardness. The wear behavior after coating of 20% Fe 20% Co 20% Ni 20% Mn 20% Cu HEA on SS-304 substrate has significantly enhanced due to the strengthened wear resistance and hardness of the coatings. Findings have exhibited that the formation of (Fe, Co, Ni, Mn, Cu)3O4 phase is a potential coating material for “SOFC interconnects” applications. Moreover, the cladding of SS304 with a composition of 20% Fe, 20% Co, 20% Ni, 20% Mn, and 20% Cu has demonstrated remarkable stability under thermal expansion studies. As the findings have revealed that the composite cladding has efficiently withstand significant variations in volume when subjected to elevated temperatures for a prolonged period of time, thus, exhibiting its superior thermal stability for SOFC-interconnect applications. Furthermore, the SEM images of the cladding surface, surface hardness, and tribocorrosion behavior of the coated material have been observed to identify the 20% Fe 20% Co 20% Ni 20% Mn 20% Cu HEA coating effect on SS-304 steel-substrate.
