Advances in Surface Finishing Technology
Microstructure and elemental characterization indicate that the finish of the coating with the LBL film resulted in a closely multilayered coating with a smoother surface. The principles of assembly are discussed together with the proprieties of nanoparticles and layer by layer polymeric assembly essential in building hybrid coatings. They represent the key components to enhance mechanical properties, enable activation by laser light or ultrasound, construct anisotropic and multi-compartmental structures and facilitate the development of novel sensors and movable particles. Here, we discuss an increasingly important role of inorganic nanoparticles in the layer-by-layer assembly-effectively leading to the construction of the so-called hybrid coatings.
The microstructure and elemental characterization indicated that the finish of the coating with the LBL- film resulted in a closely connected multilayered coating with a smoother surface. The anticorrosion performance was systematically evaluated in the simulated corrosive medium and neutral salt spray environment. The integrated coating with the LBL-film, presents an excellent anticorrosion ability with system impedance over 10-6 micro-ohms/cm2 and a self-corrosion current density two orders of magnitude lower than that of other coatings. After the acceleration test in a salt spray environment, the multilayered coatings could still show a good protective performance with almost no cracks and no penetration of chloride ions. It is believed that the as constructed multilayered coating with high corrosive properties and a fine surface state will have promising applications in the field of anticorrosion engineering.
The principles of assembly are discussed together with the properties of nanoparticles and layer-by-layer polymeric assembly essential in building hybrid coatings. Applications and emerging trends in development of such novel materials are also identified.
