Title: The Innovative Contributions of Daniel Viviani
Introduction
Daniel Viviani is a notable inventor based in Meyzieu, France. He has made significant contributions to the field of materials science, particularly in the development of protective coatings for ferrous metals. His innovative approach has led to the creation of a unique salt bath composition that enhances the corrosion resistance of metal parts.
Latest Patents
Viviani holds a patent for a "Salt bath composition based on alkali nitrates for oxidizing ferrous." This composition is specifically designed to form a layer of magnetite (Fe₃O₄) on the surface of ferrous metal parts, including those that have been nitrided. The resulting layer is impermeable and exhibits a good crystalline order, characterized by a deep black color and a corrosion potential greater than 1,000 mV. The composition includes nitrate anions and sodium and lithium cations, with the latter present in a weight proportion relative to the bath between 0.1% and 5%, preferably between 0.5% and 1.75%. Preferred formulations also incorporate sodium, potassium, and lithium cations along with nitrate, carbonate, and hydroxyl anions.
Career Highlights
Viviani is associated with the Centre Stephanois de Recherches Mecaniques Hydromecanique et Frottement, where he has been instrumental in advancing research in mechanical engineering and materials science.
