Latest Patents

One of Dong Li's latest patents involves the creation of superhard composite materials that include compounds of carbon and nitrogen. This innovative composite material features a carbon nitrogen compound, such as CN.sub.x, where x ranges from greater than 0.1 to 1.33. The compound is deposited on a metal or metal compound that promotes the deposition of substantially crystalline CN.sub.x. The carbon nitrogen compound is carefully deposited on a crystal plane of the metal or metal compound, ensuring that it is sufficiently lattice-matched with the crystal plane of the carbon nitrogen compound. This process results in a substantially crystalline structure. Furthermore, multiple layers of these compounds can be formed in an alternating sequence, creating a multi-layered, superlattice coating. This coating achieves a hardness in the range of 45-55 GPa, which is comparable to that of a boron nitride (BN) coating and approaches the hardness of diamond coatings.
