Title: Taisuke Irie: Innovator in Zn-Ni-Alloy Electroplating
Introduction
Taisuke Irie is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of electroplating, particularly in the development of Zn-Ni-alloy electroplated steel. With a total of 3 patents, his work has enhanced the corrosion resistance of steel products, making them more durable and reliable.
Latest Patents
Irie's latest patents include a product and process for preparing Zn-Ni-alloy-electroplated steel. The first patent describes a method where Zn-Ni-alloy electroplating of steel sheets is conducted using a specific plating bath. This bath contains 10-40 g/l zinc, 15-160 g/l nickel, 0.1-5 g/l cobalt, and 0.2-10 g/l titanium, along with aluminum or magnesium salts. The pH of the solution is maintained between 1.5-2.5. The resulting plated product exhibits excellent corrosion resistance and peeling resistance. Additionally, the product can be subjected to heating at temperatures ranging from 60 to 200 degrees Celsius, preferably using hot water, steam, or atomized water mist, which further enhances its corrosion resistance.
The second patent focuses on an improved process for preparing Zn-Ni-alloy electroplated steel sheets. This process involves electroplating a steel sheet with an acid electroplating bath containing Zn ions, Ni ions, and a small amount of titanium ions. It is recommended to pre-electroplate with a bath containing a larger amount of Ni ions before heating the plating sheet in the presence of water.
