| Abstract Scope |
Vitreous enamel coatings offer excellent wear, thermal, and corrosion resistance but suffer from brittleness under mechanical stress. This study explores the reinforcement of enamel with ductile 316L stainless steel flakes to improve mechanical reliability. 316L is selected for its ductility,thermal compatibility, and corrosion resistance with enamel. Composite formulations containing 1 wt.% and 5 wt.% flakes demonstrated enhanced fracture toughness and energy dissipation. Mechanical behavior was evaluated through indentation fracture tests and finite element analysis (FEA), simulating real-world tank applications. FEA assessed thermal stresses, residual stress during cooling, and crack propagation. Coating thickness optimization was also performed to balance strength and flexibility. Microstructural analysis confirmed improved bonding and reduced brittleness. The findings support the development of mechanically robust enamel coatings suitable for domestic appliances, offering improved durability and fatigue resistance compared to conventional systems. |
