Abstract
A method to apply nano-crystalline diamond onto a selected substrate, including preparing Nanodiamond slurry of nanodiamond particles dispersed in a medium. The medium may include a liquid or a sol-gel. The selected substrate is immersed in the Nanodiamond slurry for a predetermined period of time. Then the substrate is removed from the slurry. The substrate is then dried with a flow of inert gas. The substrate is left coated with a coating of the nanodiamond particles that are highly adherently held by van der Waals forces.
