英文摘要 | Nature armors, such as abalone nacre and crustacean exoskeleton are hierarchically-structured multilayer composites of inorganic minerals and organic proteins which possess excellent mechanical properties and superior toughness. The organic and inorganic interfaces resist or deflect crack propagation and prevent the composites from catastrophic failure. Ceramic-based protective coatings with high hardness, wear and corrosion resistance have been extensively investigated. However, their brittle mechanical behavior and poor toughness limit the commercial applications. By combining a hybrid coating system of reactive RF sputtering and pulsed laser deposition, multilayer coatings with various thickness, organic/inorganic ratio were synthesized. Microstructural features were characterized by scanning electron microscope (SEM). Nano-indentation tests were conducted to evaluate the mechanical performance of multilayer films. The fracture toughness was determined by an energy-based method to eliminate the influence of substrates. Toughening mechanisms at the organic/inorganic interfaces were elucidated, which may lead to optimal designs for multifunctional protective coatings. |
