Latest Patents
Nishimura's latest patents focus on methods for producing Zn-Ni alloys that are essential for various industrial applications. One of his notable inventions is a method for producing a Zn-Ni alloy by melting in the presence of a flux. This alloy, characterized by a high nickel content, is utilized for supplying Ni²⁺ and Zn²⁺ ions into acidic plating baths and for hot dip galvanizing. The innovative aspect of this alloy lies in its production using a flux that consists of a fused-salt former, which forms a salt with a melting temperature of 700°C or less, along with Na₂B₄O₇ and occasionally Na₂CO₃. This method allows for quick preparation of the bath, ensuring that Zn and Ni can be supplied without leaving undissolved residue.
Another significant patent by Nishimura is the method for preparation of a Zn-Ni electroplating or hot-dip galvanizing process. Similar to his previous invention, this method also employs a high Ni content Zn-Ni alloy to enhance the efficiency of the plating and galvanizing processes.
