Title: Shiyun Ruan: Innovator in Nanostructured Aluminum Alloys
Introduction
Shiyun Ruan is a notable inventor based in Arlington, MA (US), recognized for his contributions to the field of materials science, particularly in the development of nanostructured aluminum alloys. With a total of 5 patents, Ruan has made significant advancements that enhance the properties of aluminum alloys, making them more durable and resistant to various forms of damage.
Latest Patents
Ruan's latest patents include innovative techniques for creating nanostructured aluminum zirconium alloys aimed at improving anodization processes. One of his patents discloses methods for forming an enclosure comprised of aluminum zirconium alloy layers. This involves dissolving aluminum and zirconium ions in a non-aqueous ionic liquid within an electrolytic plating bath. A reverse pulsed electric current facilitates the co-deposition of these ions onto a metal substrate, resulting in an alloy layer with nanocrystalline grain structures. This advancement imparts increased hardness and enhanced resistance to scratching, denting, and abrasion. Additionally, the anodized aluminum zirconium alloy layer retains a neutral color post-anodization.
Another significant patent focuses on nanostructured aluminum alloys that improve hardness. This technique also involves dissolving aluminum ions and metal element ions in a non-aqueous ionic liquid. The resulting aluminum alloy layer, which may include chromium or hafnium ions, exhibits nanocrystalline structures that enhance its hardness and resistance to scratching, corrosion, and abrasion. Notably, the formation of a chromium oxide passivation layer does not alter the color of the aluminum alloy layer.
