Title: Junko Ozawa: Innovator in Corrosion-Resistant Alloys
Introduction
Junko Ozawa is a prominent inventor based in Chiba, Japan. She has made significant contributions to the field of materials science, particularly in the development of corrosion-resistant alloys. With a total of 2 patents to her name, her work has garnered attention for its innovative approaches to plating solutions and methods.
Latest Patents
One of her latest patents is for a highly corrosion-resistant zincate type zinc-iron-phosphorus alloy. This invention involves a plating bath with a pH of not less than 13, containing iron, phosphorus, and zinc sources. The alloy film produced has an iron content ranging from 0.1 to 30% by weight and a phosphorus content from 0.001 to 1.5% by weight, with the balance being zinc. This alkaline plating bath allows for the formation of a zinc-iron-phosphorus alloy film that exhibits excellent lustre, throwing power, and corrosion resistance. It also reduces corrosion of the plating equipment and provides excellent adhesion as an undercoat for painting.
Another notable patent is for an electroless plating solution and its associated method. This solution comprises nickel ions, a chelating agent for nickel ions, dimethylamine borane, and other components. The method involves immersing a substrate in the electroless plating solution for a sufficient time to form a nickel or nickel alloy layer. This solution is characterized by high bath stability and the ability to create a thick deposit that is free from pits and cracks.
