Latest Patents
One of Nakatani's latest patents is a method for producing a black plated resin part. This method involves electroplating a resin substrate that has an underlying plating layer in a trivalent chromium plating bath containing thiocyanic acid. The process results in a black chromium plating layer composed of trivalent chromium, which has a thickness of 0.15 μm or more. Additionally, the resin substrate is immersed in warm water at 30°C or higher for a predetermined time. The parameters of thiocyanic acid concentration, warm water temperature, and immersion time are carefully adjusted to achieve a black chromium plating layer with a b* value of -1.7 or less based on the L*a*b* color system.
Another patent by Nakatani describes a black plated resin part that includes a resin substrate, an underlying plating layer, and a black chromium plating layer formed of trivalent chromium. This layer also has a thickness of 0.15 μm or more and exhibits a b* value of 3.0 or less based on the L*a*b* color system. The chromium in this layer is present in various forms, including metallic chromium, chromium oxide, and chromium hydroxide.
