| Summary: | 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.
