Title: Innovations of Deok-Hyung Lee in Diamond-Like Carbon Coatings
Introduction
Deok-Hyung Lee is an accomplished inventor based in Garland, TX (US). He has made significant contributions to the field of materials science, particularly in the development of diamond-like carbon coatings. With a total of 2 patents, his work focuses on enhancing the properties of coatings for various applications.
Latest Patents
One of his latest patents is for "Optically transparent, scratch-resistant, diamond-like carbon coatings." This patent describes a plasma-based method for the deposition of diamond-like carbon (DLC) coatings. The process utilizes a radio-frequency inductively coupled discharge to generate plasma at relatively low gas pressures. This environmentally friendly deposition method is scalable to large areas and can process components with geometrically complicated surfaces. The resulting DLC coatings, which are between 100-400 nm thick, are three to four times harder than steel, making them scratch-resistant and transparent to visible light. Additionally, boron and silicon doping of the DLC coatings has led to improved optical properties and lower coating stress levels, albeit with slightly reduced hardness.
Another significant patent by Deok-Hyung Lee is for a "Method for producing fluorinated diamond-like carbon films." This innovation involves producing fluorinated diamond-like carbon (F-DLC) films through a pulsed, glow-discharge plasma immersion ion processing procedure. The pulsed plasma is generated at a pressure of 1 Pa from a gas mixture of acetylene and hexafluoroethane. The hardness and wear resistance of the F-DLC films are strongly influenced by the fluorine content in the coatings. Notably, the hardness decreases significantly when the fluorine content reaches about 20%. Furthermore, the contact angle of water on the F-DLC coatings increases with higher fluorine content, eventually saturating at a level characteristic of polytetrafluoroethylene.
