Quality has become one of the most crucial criteria in an institution’s success and survival as there is nothing more than what an era of globalization and intensity demands. Successful businesses recognize that consumer reliability may have a severe influence on their bottom lines. As a result, several competitive companies are constantly raising their quality requirements. Competitive companies think that improving quality is the best way to recover, and most authors have specified various procedures relevant to their processes. The majority of automobile assembly sectors are looking for high-quality requirements in their manufacturing techniques and are executing a quality system known as total productive maintenance (TPM). The study’s goal is to deploy the TPM program inside the metal forming industry to improve metal industry workstations. The overall equipment effectiveness (OEE) for various workstations such as rolling, bending, cutting, and die punching for the fiscal year 2018–2019 has been evaluated. In addition to the other reasons, inefficient resource utilization is a significant component that diminishes the factory’s OEE. In the financial year 2019–2020, the TPM approach was adopted in the enterprise. As a result, there has been an improvement in overall performance.
In this investigation, microwave radiation was used alongside a combination of Ni powder, Si powder, and La2O3 (Lanthanum oxide) powder to create surface cladding on SS-304 steel. To complete the microwave cladding process, 900 W at 2.45 GHz was used for 120 s. “Response surface methodology (RSM)” was utilized to attain the optimal combination of microwave cladding process parameters. The surface hardness of the cladding samples was taken as a response. The optimal combination of microwave cladding process parameters was found to be Si (wt.%) of 19.28, a skin depth of 4.57 µm, irradiation time of 118 s, and La2O3 (wt.%) of 11 to achieve a surface hardness of 287.25 HV. Experimental surface hardness at the corresponding microwave-cladding-process parameters was found to be 279 HV. The hardness of SS-304 was improved by about 32.85% at the optimum combination of microwave cladding process parameters. The SEM and optical microscopic images showed the presence of Si, Ni, and La2O3 particles. SEM images of the “cladding layer and surface” showed the “uniform cladding layer” with “fewer dark pixels” (yielding higher homogeneity). Higher homogeneity reduced the dimensional deviation in the developed cladding surface. XRD of the cladded surface showed the presence of FeNi, Ni2Si, FeNi3, NiSi2, Ni3C, NiC, and La2O3 phases. The “wear rate and coefficient of friction” of the developed cladded surface with 69.72% Ni, 19.28% Si, and 11% La2O3 particles were found to be 0.00367 mm3/m and 0.312, respectively. “Few dark spots” were observed on the “corroded surface”. These “dark spots” displayed “some corrosion (corrosion weight loss 0.49 mg)” in a “3.5 wt.% NaCl environment”.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
