Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from such properties. DLC exists in seven different forms. All seven contain significant amounts of sp hybridized carbon … See more In 2006, the market for outsourced DLC coatings was estimated as about €30,000,000 in the European Union. In 2011, researchers at Stanford University announced a super-hard amorphous diamond under … See more There are several methods for producing DLC, which rely on the lower density of sp than sp carbon. So the application of pressure, impact, catalysis, or some combination of these at the atomic scale can force sp bonded carbon atoms closer together into sp … See more The increase in lifetime of articles coated with DLC that wear out because of abrasion can be described by the formula f = (g) , where g is a number that characterizes the type of DLC, the type of abrasion, the substrate material and μ is the thickness of the … See more Naturally occurring diamond is almost always found in the crystalline form with a purely cubic orientation of sp bonded carbon atoms. Sometimes there are lattice defects or inclusions of atoms of other elements that give color to the stone, but the lattice … See more As implied by the name, diamond-like carbon (DLC), the value of such coatings accrues from their ability to provide some of the properties of diamond to surfaces of almost any … See more Applications of DLC typically utilize the ability of the material to reduce abrasive wear.
