“…The design expert software was employed to construct the regression analysis model and statistical correlation [25,32,35,44], and formulations of each attribute were generated, as illustrated in equations (10)(11)(12)(13)(14)(15)(16). The error percentage was determined to assess how closely the obtained results matched those predicted by the developed models.…”

This study investigated the thermophysical, physicochemical, and electrical characteristics of electrode coatings developed for application in the weld joint of nuclear power plants (NPPs).The extreme vertices design technique has been used in this work to develop the Al2O3-SiO2-CaO-Na3AlF6-based SMAW electrodes. Twenty-six electrode coating compositions were formulated, and flux coatings were milled into a fine powder for further characterization. XRD technique was utilized to investigate the structure and phases of the coating composition, and the FTIR analysis technique was employed to determine the nature of bonds. The coating's thermal characteristics, including conductivity, diffusivity, and specific heat, were evaluated using hot disk equipment. Enthalpy change and thermal stability of flux coating were determined using the TGA technique. The precision LCR instrument was used further to examine the electrical characteristics of the flux coatings. In addition, a regression model has been developed for each coating property using statistical analysis and investigated a correlation between the properties and mineral interactions. Results reveal that the individual elements and their binary and tertiary interaction significantly influence the physicochemical, thermophysical, and electrical properties of the flux coatings.
