Latest Patents

Yoshio Hayashi holds a patent for a "Method for hot-dip coating chromium-bearing steel." This patent describes a process for pretreating and hot-dip coating aluminum or aluminum alloys on a chromium-containing steel strip. The method involves annealing the final gauge steel strip in an oxygen excess atmosphere to create a chromium-rich oxide on the surface. Following this, the strip undergoes electrolytic descaling in an aqueous salt solution to remove the oxide and expose a chromium-depleted surface. The strip is then transported to a coating line, heated to a temperature at or above that of a bath of aluminum or aluminum alloy, and drawn through the bath to achieve the coating.
