Diamond is the hardest material on the Earth, and lab-grown diamond is usually even harder. Strong covalent bonding and dense structure makes them perfect for mechanical and engineering applications. Overwhelming toughness and strengths of lab-grown diamonds allow for their use in road planning and restoration tools. Lab-grown nanodiamonds are applied in auto engineering, since their unique wear and chemical resistance are a key to better and longer vehicle performances.
And that’s only a small fraction of mechanical applications. The pure crystal structure of a lab-grown diamond influences the level of wear resistance and increases a lifetime of any tool, even if a diamond layer is very thin.
