Latest Patents

Yamaki's latest patents focus on hot-dip Zn-Al-Mg plated steel sheets that exhibit excellent corrosion resistance and surface appearance. The first patent describes a method of producing a hot-dip Zn-Al-Mg plated steel sheet, which involves forming a plating layer composed of Al (4.0-10 wt. %), Mg (1.0-4.0 wt. %), and the balance of Zn and unavoidable impurities. This plating layer possesses a unique metallic structure that includes a primary crystal Al phase or a combination of Al and Zn phases. The cooling rate and plating bath temperature are carefully controlled to achieve the desired properties. The second patent further elaborates on the same technology, emphasizing the importance of morphology control of a Mg-containing oxide film to prevent stripe patterns on the plated steel sheet.
