Title: The Innovations of Jean-Michel Lemaire
Introduction
Jean-Michel Lemaire is a notable inventor based in Villers Saint Paul, France. He has made significant contributions to the field of materials science, particularly in the development of advanced metal coatings. With a total of 3 patents to his name, Lemaire's work focuses on enhancing the properties of metal sheets for various applications.
Latest Patents
One of Lemaire's latest patents involves a metal sheet having oiled Zn-Al-Mg coatings. This innovative metal sheet includes a substrate with two faces, each coated with a metal layer composed of zinc, aluminum, and magnesium. The coatings contain between 0.1 and 20 wt % of aluminum and 0.1 and 10 wt % of magnesium. Additionally, layers of magnesium oxide or magnesium hydroxide are formed on the outer surfaces of the coatings. These layers can be altered through the application of an acid solution or mechanical forces, such as those from a roller leveler or a brushing device. The metal sheet is further enhanced by a layer of oil deposited directly on the outer surfaces of the coatings.
Another significant patent by Lemaire describes methods for producing a pre-lacquered metal sheet with Zn-Al-Mg coatings. This method involves providing a steel substrate coated by dipping it in a bath, altering the layers of magnesium oxide or magnesium hydroxide, rinsing and drying the surfaces, applying a conversion solution, and finally painting the outer surfaces of the metal coatings.
