Latest Patents
One of her notable patents is for a hot dip coated steel sheet and the process for producing it. This innovation involves hot dipping a steel sheet in a metal bath comprising zinc-based or zinc/aluminum based alloy. The resulting hot dip coated steel sheet features a film of oxides, which are compounds of cobalt or iron, or both, with oxygen. This film effectively prevents color change to grayish black, particularly when spangles are minimized or when corrosion resistance-improving elements like magnesium and aluminum are included. The formation of the oxide film is achieved by spraying an aqueous solution of cobalt or iron salts onto the steel sheet's surface at temperatures of 170°C or higher.
Another significant patent involves the surface treatment of high-nickel/iron alloy steel plates designed for LNG or LPG tanks. These plates, containing 35-37% nickel, are plated with nickel and then chromated to create a protective film with a chromium content of 5 to 100 mg/m².
