Introduction

Xiao-Ming He is a prominent inventor based in Los Alamos, NM (US). He has made significant contributions to the field of materials science, particularly in the development of advanced coatings. With a total of 2 patents, his work focuses on enhancing the properties of diamond-like carbon coatings.

Latest Patents

One of his latest patents is for optically transparent, scratch-resistant, diamond-like carbon coatings. This plasma-based method for deposition utilizes a radio-frequency inductively coupled discharge to generate plasma at relatively low gas pressures. The environmentally friendly process is scalable to large areas and can accommodate components with geometrically complicated surfaces. The resulting coatings, which are between three and four times harder than steel, are scratch-resistant and transparent to visible light. Additionally, boron and silicon doping of the coatings have improved optical properties and reduced coating stress levels, albeit with slightly lower hardness.

Another notable patent involves the method for producing fluorinated diamond-like carbon films. These films are created through a pulsed, glow-discharge plasma immersion ion processing procedure. The process uses a gas mixture of acetylene and hexafluoroethane to generate the plasma at a pressure of 1 Pa. The hardness and wear resistance of the fluorinated diamond-like carbon films are significantly influenced by the fluorine content. It was observed that the hardness decreases considerably 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.
